A Living Tradition of the Americas
In the early months of 1937, a man named Daniel Pereira de Mattos was transported by ox cart, semi-conscious, to the settlement of a fellow Maranhense at the edge of Rio Branco. He had come from the northeast of Brazil like thousands of others, drawn by the rubber economy, but the decades in Acre had undone him. He had been a sailor, a barber, a musician, a craftsman of twelve trades — skilled at everything, sustained at nothing. Alcohol had destroyed his liver and driven away his wife and children. He was dying.
The man he was brought to was Raimundo Irineu Serra — Mestre Irineu — who had recently received a new religion from the spirit of the Queen of the Forest. Irineu began giving the ailing Daniel small amounts of the sacramental brew — a spoonful, then more — until his body could receive a full cup. During one ceremony, two luminous angels descended to Daniel carrying a blue book. The book contained the organization of a mission and the teaching of a new doctrine. Daniel had seen these same two angels in visions since childhood, and he recognized the moment. He reported the vision to Mestre Irineu, who authorized him to proceed.
What Daniel founded from that healing — around 1945, on the margins of a rubber plantation road, in a rustic chapel with a straw roof — was a religion he called the House of Jesus, Fountain of Light. Those outside called it simply the Barquinha: the Little Boat. It is the smallest of Brazil's three ayahuasca religions and the most eccentric: a syncretic maritime Christianity in which Catholic saints occupy the celestial heights, Afro-Brazilian spirits work the earthly level, and enchanted mermaids and swordfish patrol the sea. It is the one where the spirits do not merely appear in visions — they arrive, take up residence in the bodies of prepared mediums, and speak.
I. Origins in the Rubber Country
Daniel Pereira de Mattos was born on July 13, 1888, in São Luís, Maranhão — the same city that had given birth to Raimundo Irineu Serra. The shared origin was no coincidence. The rubber boom of the late nineteenth and early twentieth centuries had created a vast labor migration from Brazil's impoverished northeast to the new Amazonian frontier territory of Acre, which the Brazilian government had annexed from Bolivia in 1903. Thousands of Maranhense men — many of them Afro-Brazilian, many of them descended from enslaved people — moved west to become seringueiros, rubber tappers, working the wild Hevea trees of the forest interior.
Daniel did not stop at rubber tapping. At age seven he had enrolled in the Brazilian Navy as a cabin boy. He rose to the rank of Second Sergeant. He arrived in Rio Branco during the Acreano Revolution — the armed conflict of 1899–1903 in which local settlers, backed by Brazil, drove out Bolivian administration. After the conflict he requested discharge and settled in the city, where he established himself as a barber on Rua 6 de Agosto and became known throughout the community as an accomplished musician who built his own instruments and was said to have mastered twelve distinct trades: shipbuilding, cooking, barbering, tailoring, carpentry, woodworking, craftsmanship, poetry, masonry, shoemaking, baking, and music. He was respected. He was also, by the 1930s, collapsing.
Alcohol became the center of his life. His wife and children returned to Maranhão around 1937. His liver was failing. At some point in that same year, the ailing Daniel was transported to the settlement of Vila Ivonete on the outskirts of Rio Branco — to the home of Mestre Irineu, whose Santo Daime community was still small, a gathering of laborers and marginal people around the visionary doctrine the Master had received a few years earlier.
Mestre Irineu treated Daniel as one might treat a dangerously sick patient being reintroduced to food: with small amounts of the sacred brew, increased gradually until his body could receive it properly. Daniel's recovery was dramatic. The daime had done what medicine could not. And in the visionary space that the brew opened, something happened that he recognized as a calling older than his illness: the two luminous angels he had seen since childhood appeared carrying a blue book — the Livro Azul — that contained the structure of a doctrine and the mission of a new religious center. He told Mestre Irineu. He was authorized.
Around 1945 — sources vary by a year or two in either direction, and the legal formalization of the center came only in 1966 — Daniel established a small chapel on the margins of a road belonging to the Empresa rubber plantation, on land owned by a Captain Manuel Julião de Souza. It was a rustic wooden structure with a straw roof. He called it the Capelinha de São Francisco (Little Chapel of Saint Francis) in honor of the Franciscan saint who was one of his principal spiritual intercessors, and later the Centro Espírita e Culto de Oração Casa de Jesus, Fonte de Luz — the Spiritist Center and Prayer Worship, House of Jesus, Fountain of Light.
Daniel lived there like a Franciscan hermit: in voluntary poverty, practicing charity. He received the sick — those with snakebites, curses, addictions, various illnesses — and gave them care and the healing mediation of his new doctrine. He composed and received hymns. He organized mediums. He built a religion of boats.
He died on September 8, 1958 — a date near the feast of Saint Francis — at the age of seventy. The tradition describes his death as desencarnação, disincarnation, and understands him to continue active work in the spiritual dimensions accessible through ceremony.
II. The Little Boat and Its Theology
The name Barquinha — diminutive of barca, boat — was given by the community, not by Daniel himself. But it fit. The man had been a sailor; his cosmology was maritime; his mission, as the community articulated it, was salvific in the most literal sense: the little boat floats on a cosmic sea, rescuing those who are lost.
The boat metaphor is not decorative. It structures the entire tradition. The community is a vessel; each member is a sailor. Hierarchy is naval: basic participants are marinheiros (sailors), advanced members are oficiais (officers). The ceremonies are trabalhos (works), but the work is conceived as collective rowing — "no troubled waters can tip a boat in which all row in synchronicity." The entire soteriological vision is maritime: the cosmos is a sacred sea navigated between Heaven, Earth, and Ocean; the saints are pilots; the enchanted beings of the deep sea are both destination and danger; and the daime, the sacred brew, is the medium that allows a sailor to perceive the currents beneath the surface.
The Livro Azul — the Blue Book — is the founding symbol of this navigation. It appeared to Daniel in his founding vision; it contained the structure of his mission and the hymnal of his doctrine. It is not a physical text that functions as scripture. Rather, it is a symbolic transmission — the shape of a mission rather than a codified law — and it is blue because blue is the color of the divine, the ocean, and Barquinha ceremonial dress. The Blue Book is the mission. The mission is the boat.
The maritime metaphor also carries a social history. Most early Barquinha members were northeastern Brazilians — many of them Afro-Brazilian, many descended from the enslaved — who had migrated to the rubber frontier. The marinheiro framework offered something the wider Brazilian society had largely denied them: order, dignity, rank, and purpose. You are not merely a rubber tapper or a barber's customer. You are a sailor in a sacred navy, with a rank, a duty, and a role in the rescue of lost souls.
III. The Three Realms
The cosmology of Barquinha is organized around three planes of existence, each with its own spiritual inhabitants and corresponding to one of the three religious streams woven into the tradition.
Céu (Heaven) is the domain of Catholic saints, angels, and the highest spiritual beings. Jesus Christ and the Virgin Mary — addressed as Virgem da Conceição, the Virgin of the Conception, and also as a Rainha, the Queen, in her aspect of Marian queenship — occupy the highest positions. Saint Francis of Assisi, Saint Sebastian, and Saint Joseph function as pilots of the sacred boat. The Catholic contribution to Barquinha cosmology is at its most pronounced in this celestial register: Stations of the Cross displayed in the main church hall, months of pilgrimage and penitential devotion to each major saint, prayer forms drawn directly from popular Catholic practice. The entities of this realm do not possess human mediums — their power and spiritual density is understood to be too great for a human body to contain without damage. They irradiate, inspire, and instruct, but they do not take up residence in flesh.
Terra (Earth) is the domain of the intermediate spirits: the pretos velhos (spirits of enslaved African ancestors, addressed as grandfather and grandmother), the caboclos (spirits of indigenous peoples, described as fiercely independent), and the exus (liminal beings of crossroads and transitions from the Afro-Brazilian tradition). These are the working spirits — healers, counselors, counter-sorcery practitioners. They occupy the level of the ordinary world because that is where their work is: addressing illnesses, curses, addictions, grief, disrupted relationships, the accumulated damage of ordinary human life. They can and do incorporate into prepared mediums, particularly during healing ceremonies.
Mar (Sea) is the most distinctive register of Barquinha cosmology, and the one that marks it most clearly as an Amazonian religion rather than a transplanted African or European one. This is the domain of the encantados — the enchanted beings of the aquatic imagination: mermaids (sereias), boto dolphins, wood spirits (curupiras), dragons, swordfish, and a range of other mythological figures drawn from Amazonian cosmology and Afro-Brazilian Candomblé de Caboclo. The most important figure in this register is Príncipe Espadarte — the Swordfish Prince — the entity who first incorporated into the primary medium of Daniel's community, Madrinha Francisca Campos do Nascimento, and who gave her center its name. The sea realm is the most syncretic in character: it weaves together indigenous Amazonian aquatic mythology, Afro-Brazilian encantado traditions, and the founder's own maritime biography into a third cosmological register that neither of the other Brazilian ayahuasca religions has developed.
The cosmology also includes an Astral — an intermediate plane populated by beings still in spiritual preparation, a kind of purgatory within which moral development continues. Barquinha, following the Kardecist Spiritism widely influential in Brazilian popular religion, understands the cosmos as a moral education across successive incarnations. The spirits who arrive in ceremony are beings at various stages of that education: some offering advanced guidance from their accomplished state, others still confused or troubled, arriving at the healing ceremonies to receive care alongside the human participants.
The scholar Wladimyr Sena Araújo, who produced the foundational academic study of Barquinha, characterizes this cosmology as a "cosmologia em construção" — a cosmology in construction. It is not a fixed system derived from a single source but an ongoing synthesis, absorbing new entities and new relationships as the community encounters them. Afro-Brazilian entities that carry ambivalent or threatening qualities in their originating contexts are, in the Barquinha framing, understood as beings on a path toward salvation — capable of moral development, convertible to Christian doctrine, capable of becoming, over time, "pacified" and aligned with the divine order.
IV. Ceremony and the Life of the Spirits
Barquinha ceremony is more ritually elaborate than either Santo Daime or União do Vegetal. Where UDV's sessões are seated and pedagogical — tea consumed, chamadas sung, doctrine discussed — and Santo Daime's main trabalhos are collective dances with maracas, Barquinha holds multiple distinct ceremony types with substantially different characters.
Instrução Ritual (Ritual Instruction) is the main ceremony. Participants gather in the church hall, which is hung with Catholic iconography: Stations of the Cross on the walls, painted saints and angels in niches, flowers and candles in arranged shrines. The spatial layout encodes cosmological hierarchy — Catholic representations occupy higher positions; objects from Afro-Brazilian or indigenous traditions are placed below. Ceremony opens with specific hymns designed to invite spiritual reinforcements, then alternates between Catholic prayers and salmos — the sacred hymns specific to Barquinha — sung for hours. During this time, spirits descend to irradiar (irradiate) mediums with their presence, delivering teachings, instructions, and moral guidance through the mediums or independently sensed by practitioners in their individual visionary states.
Obras de Caridade (Works of Charity) are Saturday healing ceremonies — the expression, in ritual time, of Daniel's original ministry. Healers work with specific spirit-guides who diagnose and treat illness, curses, emotional disturbance, and the effects of harmful sorcery. The paraphernalia of the working spirits occupies center stage during these ceremonies: pontos riscados (magical chalk drawings with lit candles, from Umbanda practice), the Pedra de Xangô (a stone associated with the Yoruba deity Xangô, used in Candomblé), and various therapeutic objects from the Afro-Brazilian traditions. The spatial hierarchy of the main hall is effectively inverted for the duration of healing work: the saints remain on their shelves, but the tools of the working spirits are at the center.
Terreiro Rituals are outdoor ceremonies with a distinctly different character. Drumming occurs here — drums do not enter the main church hall. Spirit possession is more pronounced. The bailado danced in the outdoor space is less constrained than the interior ceremony: spirits who have incorporated into mediums may break from the collective pattern to move according to their own character, including pretos velhos who manifest with the restricted, stooped movements of the elderly ancestors whose personalities they carry.
The Bailado within the church hall follows a different pattern: participants dance counter-clockwise in a single-file ring, as in Santo Daime, but without the Santo Daime bailado's use of maracas as the primary rhythmic instrument.
Daime in Barquinha holds a distinctive status. The sacred brew — prepared from Banisteriopsis caapi vine and Psychotria viridis leaf — is called "Santo Daime" or "daime," following Santo Daime's terminology rather than the UDV's "vegetal." It is treated as a sacred being: candles are always burning during its service, and the objects of its preparation are reserved exclusively for that purpose. But Barquinha is the only one of the three Brazilian ayahuasca religions in which the daime is not present in every ceremony. Some works are conducted without it. The tradition's teaching is that spiritual development does not depend solely on the plant medicine. Regular participants who do not consume the brew are recognized and included in a way that neither Santo Daime nor UDV accommodates.
The Miração is the visionary experience induced by the brew — from the Portuguese mirar, to look or gaze upon. In Barquinha, the miração is understood as the spirits showing the practitioner something: a revelation of one's spiritual state, a diagnosis of illness, an image that provides critical insight into suffering. The anthropologist Marcelo Mercante, whose doctoral research at Saybrook Graduate School focused specifically on the miração in Barquinha's Príncipe Espadarte center, characterizes these experiences as "spontaneous mental imagery" and studied their role in healing processes extensively. The miração is distinct from spirit possession — it is an interior visionary state rather than the partial or full inhabitation of the body by another entity — but both may occur in the same ceremony, in the same person, and both are understood as spiritually real.
Mediumship in Barquinha occupies a spectrum. The tradition distinguishes between irradiação — in which a spirit partially occupies a medium, influencing thoughts, speech, and affect without full takeover — and incorporação, in which possession is more complete. The degree to which full incorporação occurs varies by center: the original lineage emphasizes controlled irradiation as safer and more appropriate for most spirits; Madrinha Francisca's Príncipe Espadarte center has developed a more fully possessory practice, understood as providing greater freedom for the spiritual beings to do their work. In all Barquinha contexts, the highest entities — the major saints and divine beings of the celestial register — do not incorporate. Only intermediate-level spirits (pretos velhos, caboclos, encantados) work through human bodies.
When a spirit descends to speak during ceremony, assistants place microphones near the medium. The congregation listens. The spirit may give a teaching, respond to a specific question, or work directly on a person in need of healing. When finished, the spirit withdraws, and the medium returns to their ordinary state, often without detailed memory of what was said.
V. The Three Brazilian Traditions
Barquinha shares its Amazon origin, its Catholic-syncretic character, and its sacramental use of ayahuasca with Santo Daime and União do Vegetal, but the three are not three versions of the same religion. They are three distinct answers to the same Aquarian question — how does the sacred reorganize itself in the wreckage of industrial modernity, in the Amazonian interior, among the forgotten poor? — and the answers are strikingly different.
Santo Daime was the mother tradition. Mestre Irineu founded it around 1930 in Rio Branco after his visionary encounter with the Queen of the Forest. The tradition is centered on a body of revealed hymns — Daniel's teacher received approximately 130 over his lifetime — and its primary form of worship is the bailado, a counter-clockwise communal dance with maracas that may continue for many hours. The hymnary contains the doctrine. Learning the hymns is learning the theology. Santo Daime's founding gesture was musical and feminine: a Black man told by a luminous woman inside the moon to open his mouth and sing.
Barquinha emerged directly from Santo Daime. Daniel Pereira de Mattos was Mestre Irineu's disciple; the Barquinha is, as Santo Daime's own institutional history acknowledges, "the first branch of Santo Daime." Daniel received the daime from Irineu's hands and was authorized by him to found his own center. The central texts of both traditions — the hymns and salmos — are received by the same mechanism: dropped into prepared individuals in visionary states, understood not as compositions but as transmissions. Both call the brew daime. But where Santo Daime's practice is primarily musical and communal, Barquinha's is medical and possessory: the center of gravity shifts from the healing that occurs in the collective ecstasy of the dance to the healing that occurs in the direct intervention of a spirit speaking through a medium's body. Barquinha is also far more explicitly Afro-Brazilian than the main lineages of Santo Daime — the pretos velhos, caboclos, and encantados are central to Barquinha ceremony in a way they are not in Santo Daime's primary liturgical forms.
União do Vegetal has no lineage connection to Mestre Irineu or Daniel. Mestre Gabriel da Costa had his own independent encounter with ayahuasca in the rubber camps of Acre in 1959 and founded the UDV in Porto Velho, Rondônia in 1961. The UDV calls the brew vegetal or hoasca; it calls its practitioners sócios (associates); its ceremonies are seated and pedagogical, without dance, without elaborate music, without spirit possession of any kind. The UDV's founding myth is explicitly about restoration and recovery — Solomon's ancient mysteries, transmitted across millennia, finally recovered in the Amazon — where Mestre Irineu's and Daniel's myths are about revelation: the divine breaking through from outside into a prepared and suffering vessel. This different founding orientation shapes everything downstream. The UDV is the most hierarchical, the most institutionally controlled, the most doctrinally systematic of the three. It has won a US Supreme Court case establishing the right of its members to use ayahuasca under the Religious Freedom Restoration Act. It has twenty-four thousand members across more than two hundred congregations in eleven countries. It is, by every measure of institutional success, the most successful of the three.
Barquinha is not interested in institutional success. It is, by the same measures, the opposite of the UDV: small, scattered, non-expansionist, having made no effort to spread internationally, having chosen not to participate in Brazilian government regulatory negotiations for ayahuasca use, having remained largely within the state of Acre. This insularity is not failure. It is a theological position: the little boat does not try to become a fleet.
VI. Texts, Music, and Scholarship
Barquinha has no published canonical scripture. The Livro Azul of the founding vision is symbolic, not textual — a revelation of a mission's structure rather than a book to be read. The hymns and salmos that constitute the liturgical core of the tradition are received spiritually by individual practitioners, taught to the community, and understood as belonging to the divine rather than to their human vehicles: "they don't own the songs; they're just vehicles for the expression of them." An ever-expanding hymnary, transmitted orally and in handwritten collections within the communities, constitutes the closest thing to canonical text that Barquinha possesses.
No comprehensive freely accessible database of Barquinha salmos has been identified. Unlike Santo Daime's hymnal — extensively documented online at community archives such as NossaIrmandade.com — Barquinha's hymns remain largely within the tradition. The most accessible documentation of Barquinha sacred music is the two albums recorded by the filmmaker and musician Vincent Moon (Petites Planètes) at the Centro Espírita Daniel Pereira de Matos in Rio Branco in 2014, released in December 2017. These recordings are available on Bandcamp under a Creative Commons Attribution Non-Commercial Share Alike license — the only Barquinha sacred music confirmed to be freely available. A companion documentary film by Moon is available at hibridos.cc.
Academic scholarship on Barquinha is thin relative to the other ayahuasca religions but has been building since the 1990s. The foundational monograph is Wladimyr Sena Araújo's Navegando Sobre as Ondas do Daime: história, cosmologia e ritual da Barquinha (Editora da Unicamp, 1999), the only book-length academic treatment of the tradition in its own right. Araújo, based at UNINORTE in Rio Branco and an associate researcher at the NEIP (Núcleo de Estudos Interdisciplinares sobre Psicoativos) network, developed the concept of Barquinha as a "cosmologia em construção" — a cosmology in construction — that appears in subsequent scholarship. His article "The Barquinha: Symbolic Space of a Cosmology in the Making" (Fieldwork in Religion 2(3), 2006) is the primary English-language academic entry point.
The second major figure is Marcelo Mercante, whose 2006 doctoral thesis at Saybrook Graduate School — Images of Healing: Spontaneous Mental Imagery and Healing Process of the Barquinha — studied the miração as a healing modality specifically at the Príncipe Espadarte center. Published as Imagens de Cura: Ayahuasca, imaginação, saúde e doença na Barquinha (Editora Fiocruz, 2012). His 2015 article "Barquinha: Religião Ayahuasqueira, Afro-Brasileira ou Afro-Amazônica?" (PLURA, Revista de Estudos de Religião 6(2)) addresses the tradition's hybrid religious identity.
Christian Frenopoulo (University of Regina) produced the closest thing to a general synthetic account of Barquinha ceremony and cosmology in English: "Healing in the Barquinha Religion" (REVER 4(1), 2004; Fieldwork in Religion 2(3), 2006; also a chapter in Labate and MacRae, eds., Ayahuasca, Ritual and Religion in Brazil, Equinox/Routledge, 2010). Beatriz Caiuby Labate's extensive bibliography on Brazilian ayahuasca religions (see Ayahuasca Religions: A Comprehensive Bibliography and Critical Essays, MAPS Publishing, 2008, and her edited volume with MacRae) provides essential context for situating Barquinha within the broader field.
Sandra Goulart's comparative analysis of the three traditions (O Uso Ritual da Ayahuasca, 2002, co-edited with Labate) and the University of Hawaii dissertation by Luiz Ferreira on music and miração at Príncipe Espadarte represent the growing body of Brazilian academic work on this tradition. Ricardo Assarice dos Santos' recent A Híbrida Barquinha (Editora Dialética) offers a comprehensive recent synthetic treatment. The Encyclopedia of Latin American Religions (Springer, 2019) contains a paywalled entry on Barquinha.
No World Religions and Spirituality Project (WRSP) entry dedicated to Barquinha has been identified.
VII. Current Status
Barquinha remains centered in Rio Branco, Acre, with three primary lineages operating in that city, each descended from the original community Daniel Pereira de Mattos built.
The original center — Centro Espírita e Culto de Oração Casa de Jesus, Fonte de Luz — passed to Antônio Geraldo da Silva in 1959 and then to Manuel Hipólito de Araújo in 1979. Antônio Geraldo subsequently founded his own center, the Centro Espírita Daniel Pereira de Mattos — the center documented in Vincent Moon's 2014 recordings — which his son Antônio Geraldo Filho now leads. The third and most academically studied lineage is the Centro Espírita e Obras de Caridade Príncipe Espadarte, founded in 1991 by Francisca Campos do Nascimento (Madrinha Chica Gabriel) — who had served as Daniel's primary medium since 1957, the first person he authorized to incorporate — and dedicated to the sea-spirit Príncipe Espadarte. A formal memorial to Madrinha Francisca is registered in the national Museus Brasileiros registry. She remains the most prominent living figure in the Barquinha tradition.
Outside Acre, Barquinha has authorized a small number of centers: in Ji-Paraná (Rondônia), Rio de Janeiro, Niterói (the Barquinha RJ center, affiliated with the Príncipe Espadarte lineage, established around 2010), Fortaleza (Ceará), and the Templo Espírita Barca do Luar in southern Brazil, which emerged in 2013. No established centers have been identified outside Brazil. Barquinha has made no systematic effort toward international expansion — a theological position, not a failure of logistics. The little boat does not try to cross every ocean.
No major legal controversies have been documented. When Brazil's CONAD established a Multi-Disciplinary Working Group in 2010 to formally regulate ayahuasca use, Barquinha sent a letter declining to participate. This non-engagement has kept the tradition out of the academic and journalistic visibility that attaches to legally consequential religious freedom cases — but it has also meant that Barquinha remains, as scholars consistently note, "the least studied" of the three Brazilian ayahuasca religions, despite being, in some ways, the most theologically complex.
The Legislative Assembly of Acre recognized Daniel Pereira de Mattos, alongside Raimundo Irineu Serra and José Gabriel da Costa, with citizenship titles in 2010 — a formal acknowledgment of his foundational role in the Amazonian religious heritage that the state now partly defines itself by.
In 2010, IPHAN (Instituto do Patrimônio Histórico e Artístico Nacional) engaged with the ayahuasca religions of Acre in an ongoing process of recognizing the religious use of ayahuasca as Brazil's intangible cultural heritage. Barquinha is included in that process, though, as in the CONAD negotiations, it has remained characteristically quiet.
The little boat keeps sailing. It is not trying to become the largest vessel on the sea.
