Sun-dried mud brick, the primary building material of traditional New Mexican architecture. The warm earthen tones of adobe walls are part of the visual landscape that shaped the retablo color palette — ochres, terracottas, and dusty golds.

The main altar of a church, typically featuring an elaborate retablo mayor — a large painted or carved altarpiece — as its visual centerpiece. The altar mayor was the spiritual heart of a colonial New Mexican church.

A traditional warm corn-based drink common in New Mexican and Mexican homes. Mentioned here because the domestic rituals of daily life — including prayers before a home altar over atole in the morning — were the living context in which retablos functioned.

The second step in the Catholic process of declaring sainthood. A beatified person receives the title "Blessed" and may be publicly venerated in a specific diocese or religious order, but not yet universally. Beatification typically requires verification of one miracle through the candidate's intercession.

The liquid medium that holds pigment particles together and adheres them to the painting surface. Traditional New Mexican santeros used egg tempera (egg yolk diluted with water) as their primary binder. The egg proteins cross-link as they dry, creating a hard, matte, durable film.

A three-dimensional carved wooden figure of a saint, the Virgin Mary, or a sacred personage. Made from cottonwood root, then gessoed and painted with mineral pigments. The bulto is the sculptural counterpart to the flat retablo. Together, a painted retablo backdrop and a carved bulto figure made up the traditional New Mexican home altar.

El Camino Real de Tierra Adentro ("The Royal Road of the Interior") — the historic trade and supply route connecting Mexico City to Santa Fe, New Mexico, stretching over 1,500 miles. For two centuries, this road was the only formal supply line for New Mexican colonists. Its difficulty and infrequency directly caused the material isolation that shaped the distinctive local santero tradition.

The formal declaration by the Pope that a person is definitively in heaven and worthy of universal veneration by the entire Catholic Church. A canonized person is a Saint (with a capital S). The process typically requires two verified miracles after beatification.

Dr. Charlie Carrillo — perhaps the most important contemporary figure in the New Mexican santero tradition. A scholar-practitioner based in Santa Fe, Carrillo conducted pioneering research into pre-contact pigment sources used by historic santeros and has taught and mentored a new generation of artists. His work bridges rigorous historical scholarship and living devotional practice.

A paint binder made from milk protein (casein), sometimes used as an alternative to egg tempera. Casein paint dries quickly and produces a chalky, matte surface similar to egg tempera.

Populus deltoides — the large riparian tree native to river valleys throughout the American Southwest. Cottonwood root was the preferred material for carved bultos in New Mexico, valued for its workability, lightness, and the somewhat fibrous texture of root wood, which holds carving detail well.

A retablo in two hinged panels, designed to fold shut for protection and transport. Dípticos were favored by travelers and missionaries who needed portable devotional objects.

Art created specifically to support religious practice, prayer, and meditation — as distinct from art made for display, decoration, or secular purposes. Retablos are devotional art: their primary function is to be prayed before, not to be admired at a distance.

Colors derived from naturally occurring mineral deposits — iron oxides, ochres, siennas, and umbers — mined or gathered from the landscape. New Mexican santeros relied heavily on local earth pigments: the red cliffs of northern New Mexico yielded iron-rich ochres; copper deposits produced greens and blues; local gypsum provided white. Charlie Carrillo's research has identified specific historical pigment sources used by 18th-century masters.

A painting technique using egg yolk as the paint binder, mixed with water and dry pigments. Egg tempera dries rapidly, produces a luminous, matte finish, and is remarkably durable — examples from medieval Europe and colonial New Mexico have survived centuries without major color change. It is the primary medium of the historic New Mexican retablo tradition.

From the Latin "from a vow." A devotional offering made to a saint in fulfillment of a vow or in thanksgiving for a prayer answered. In Mexico, ex-votos often take the form of small painted tin panels depicting the moment of crisis, the miraculous intervention, and a text of gratitude. In New Mexico, ex-votos more commonly take the form of physical objects — milagros, photographs, flowers, or mementos — left at shrines.

The day in the Catholic liturgical calendar dedicated to a particular saint — traditionally the anniversary of their death, considered their "heavenly birthday." Feast days are occasions for prayer, celebration, and sometimes community festivals. Many retablo owners use feast days as occasions for special prayer before their saint's image.

One of the most important identified New Mexican santeros, active in northern New Mexico in the late 18th and early 19th centuries. Fresquís is known for his distinctive graphic style, his use of vivid local pigments, and a body of work that demonstrates a confident personal vision within the traditional vocabulary. His works are held in major museum collections.

The collection of images depicted on or around a retablo — the saints, symbols, and sacred scenes that populate the composition. Not to be confused with an art gallery; in retablo terminology, the "gallery" refers to the iconographic program of the work itself.

The white primer ground applied to a wooden support before painting. Traditional gesso (also called "true gesso") is made from gypsum or chalk ground with animal hide glue — a recipe unchanged from medieval Europe. Applied in multiple thin layers, sanded smooth between coats, gesso creates the luminous white foundation that makes painted colors appear bright and jewel-like. The characteristic cracking of aged gesso across old retablos is one of their most distinctive visual signatures.

The prepared surface on which a painting is made — in the case of retablos, the gesso layer applied to the wooden panel. The character of the ground profoundly affects the final painting: a smooth, bright gesso ground produces luminous, jewel-like color; a rough or poorly prepared ground results in dull, uneven paint.

The biography of a saint — from the Greek hagios (holy) + graphos (writing). Hagiographies range from rigorously historical accounts to highly legendary narratives. They are the primary source of information about saints' lives, patronages, and miraculous deeds, and formed the iconographic "source material" that santeros drew from when depicting specific saints.

A term used in art history to describe a formal, frontal, rigidly posed figure that communicates authority or sacred status through symbolic rather than naturalistic means. The figures in New Mexican retablos are often described as hieratic — they face the viewer directly, their proportions are intentionally skewed to emphasize spiritual importance, and they communicate through symbol and convention rather than gesture or expression.

An adhesive made by boiling animal hides (typically rabbit or deer), skimming the resulting gelatin, and drying it into sheets or granules. Hide glue was the primary adhesive and binder in traditional New Mexican gesso. It is hygroscopic (absorbs moisture from the air), which is one reason old retablos sometimes show gesso cracking — seasonal changes in humidity cause the hide glue to expand and contract slightly over time.

The system of visual symbols, attributes, and conventions used to identify and communicate the identity and meaning of a sacred figure. Each saint in the Catholic tradition has a specific iconographic "program" — characteristic garments, symbols, and attributes that tell the knowledgeable viewer who they are without requiring a label. St. Francis: brown habit, birds, stigmata. St. Anthony: Christ Child, lily. St. Lawrence: gridiron. St. Lucy: eyes on a plate.

The act of praying on behalf of another — or, in Catholic theology, asking a saint to bring one's prayers before God. The belief that saints in heaven can intercede effectively for those still living is central to Catholic devotional practice. Retablos serve as focal points for this intercessory prayer, directing the supplicant's attention and intention toward a specific heavenly advocate.

To call upon a saint in prayer — to address them directly, naming them and asking for their assistance or intercession. "St. Joseph, patron of workers, intercede for us." Invoking a saint is not worship (which is reserved for God alone in Catholic theology) but a form of veneration and petition — asking a holy person to pray for you.

An unidentified but highly significant santero active in New Mexico around 1795–1810, named for the major altarpiece they created at the Laguna Pueblo mission church — one of the finest surviving examples of New Mexican colonial sacred art. The Laguna Santero's identity remains unknown, making them one of the most intriguing mysteries of the tradition.

A retablo painted on thin sheet metal — typically tin or copper — rather than wood. More common in Mexico than in New Mexico, láminas were practical for ex-votos and portable devotional objects. The reflective quality of the metal ground gives lámina paintings a distinctive luminosity.

Small peeled poles or branches (often cedar or aspen) used in traditional New Mexican construction as ceiling material, layered across the vigas (main ceiling beams). Not directly related to retablos, but part of the architectural context in which retablos were originally displayed.

Someone who died for their faith — who chose death rather than renounce their religious beliefs. In Catholic tradition, martyrdom is understood as the highest form of witness and immediate entry into heaven. Many of the earliest saints were martyrs; their deaths are commemorated on their feast days. In retablo iconography, martyrs are typically depicted holding the palm of martyrdom and often the instrument of their death.

Spanish for "miracle." A small metal charm — often depicting a body part, animal, or person — offered at a shrine or placed on a retablo or nicho as an ex-voto offering or petition. Milagros are typically pressed or stamped from inexpensive tin, silver, or gold. A collection of milagros pinned to a retablo is itself a visual record of community devotion and petition.

An identified New Mexican santero active in the early 19th century, known for his bold, somewhat austere style and distinctive handling of facial features. Molleno's works show strong individualism within the traditional form and are considered among the most powerful examples of the New Mexican school.

A small enclosed shrine, typically made of wood, tin, or found materials, designed to house a retablo, bulto, or devotional image. A nicho functions as a miniature home altar — an enclosed sacred space that frames, protects, and consecrates the object within. Nichos are often decorated with milagros, dried flowers, fabric, and personal mementos.

A form of Catholic prayer consisting of the same prayers repeated over nine consecutive days (from the Latin novem, "nine"). Many saints have specific novenas — sets of prayers addressed to them, traditionally prayed before their feast day. Praying a novena before a saint's retablo is a form of intensified devotion.

The specific situations, groups, professions, or conditions with which a particular saint is associated as a spiritual advocate. Patronages develop over centuries through legend, miracle accounts, and popular devotion. Knowing a saint's patronages is key to understanding why a particular retablo might be chosen as a gift or devotional object.

The dry, powdered coloring material that gives paint its color. In the retablo tradition, pigments were originally obtained by grinding mineral, vegetable, or animal materials: red and yellow from iron oxide clays, blue from azurite or indigo, green from malachite or verdigris, black from charcoal or manganese oxide, white from gypsum or lead.

A stylized palm branch held by martyred saints in iconographic convention — a visual signal to the viewer that the depicted saint died for their faith. The palm has been a symbol of victory and triumph since ancient times; in Christian art it became the symbol of spiritual victory over death.

A container designed to hold a relic — a physical remnant of a saint's body or personal objects associated with them. Reliquaries range from tiny lockets to elaborate architectural structures. In New Mexican tradition, small relics were sometimes incorporated into the base of bultos.

A physical object associated with a saint — a fragment of bone, a piece of clothing, an object they touched. First-class relics are parts of the saint's body; second-class are items they owned or wore; third-class are objects that have touched a first-class relic. Veneration of relics has been central to Catholic devotional practice since the earliest centuries of Christianity.

From the Latin retro tabula, "behind the altar." In its broadest sense, any devotional painted panel — from the great altarpieces of European cathedrals to the small personal panels of New Mexican santeros. In North American popular usage, the term most commonly refers specifically to the small painted wooden panels of the New Mexican tradition. Not to be confused with the Peruvian retablo, which is a three-dimensional box shrine.

The great altarpiece at the front of a church — the original, largest, and most elaborate form of retablo. New Mexico's mission churches contain some of the finest surviving retablo mayores in North America, including the famous example at Laguna Pueblo and the reconstructed altar at the Museum of Spanish Colonial Art in Santa Fe.

The feminine form of santero — a woman who makes santos. While the historic santero tradition was predominantly male, women have always been important makers of devotional objects in the broader tradition, and many of today's most respected contemporary santeros are women.

The maker of santos — the sacred art objects of the New Mexican tradition, including retablos, bultos, and nichos. Historically, the santero was a revered community figure with both technical skill and spiritual vocation. The term carries connotations of craft, devotion, and cultural continuity that the simple word "artist" does not fully convey.

Spanish for "saint." Used broadly in New Mexico to refer to any sacred image or figure — a painted retablo, a carved bulto, a printed holy card. "Santos" (plural) is commonly used as a collective term for the sacred art objects of the New Mexican tradition.

Founded in Santa Fe in 1925, this organization was pivotal in the revival of New Mexican traditional arts, including the santero tradition. By collecting, exhibiting, and commissioning work from living artists, and by creating markets for traditional crafts at annual fairs, the Society helped keep the retablo tradition alive through the 20th century.

Spanish for "board" or "plank" — the wooden panel support on which a retablo is painted. The character of the tabla profoundly affects the final painting: the grain of the wood, the way it was cut, and the quality of the gesso applied to it all influence how the painting looks and ages.

A paint in which the pigment is bound with an emulsion — most classically egg yolk (egg tempera). Distinguished from oil paint, which uses linseed or walnut oil as the binder. Tempera dries more quickly than oil, produces a more matte finish, and tends to crack differently over time. The historic New Mexican retablo tradition used egg tempera almost exclusively.

A retablo in three hinged panels — a central panel flanked by two wings that fold shut for protection. Triptychs were common in European medieval and Renaissance art and were adapted for the portable retablo tradition in Spanish Colonial contexts.

Spanish for "candle." Candles are among the most common devotional offerings placed before a retablo or at a home altar, representing prayer, vigil, and the light of faith.

The honor and respect shown to a saint — distinct from worship (latria), which is reserved for God alone in Catholic theology. Veneration (dulia) is the proper term for the honor given to saints; the higher form of veneration given to the Virgin Mary is called hyperdulia. When Catholics pray before a retablo, they are venerating the saint depicted, not worshipping the object itself.

The large round roof beams of traditional New Mexican architecture — typically pine logs stripped of bark and left in their natural round form. Vigas span the ceiling of a room and support the latilla layers above. In a traditional New Mexican home, a retablo might hang on a whitewashed adobe wall directly below the vigas — its most natural setting.

Spanish for gypsum — the naturally occurring calcium sulfate mineral used as the primary ingredient in traditional New Mexican gesso. New Mexico has abundant gypsum deposits; historic santeros gathered and processed local yeso for their gesso grounds, contributing to the distinctive chalky, mineral quality of New Mexican retablo surfaces.
