What it is
A devotional Advent treatise written in 1476 by Hernando de Talavera at Queen Isabella I's explicit request, adapting a sermon he had delivered as prior of the Hieronymite convent of Santa María de Prado in Valladolid. Presented to the queen in January 1476 during the crisis of the Portuguese invasion, it called all loyal Christians to 'renew themselves in spirit' through examination of life, interior repentance, and active charity. The sole surviving manuscript is held in the Lázaro Galdiano Library, Madrid. Scholars regard this as the foundational moral and spiritual programme that shaped Isabella's entire model of queenship and inaugurated the series of conscience-formation texts Talavera produced exclusively for her use.
Why it still matters
Talavera's three-part Advent arc of self-examination, repentance, and charity maps cleanly onto a modern personal retreat or Advent devotional; the treatise can be used to structure four weeks of guided spiritual renewal.

Breve forma de confesarse
Breve forma de confesar, reduciendo todos los pecados mortales y veniales a los diez mandamientos
A vernacular confession manual by Isabella's confessor Hernando de Talavera, organising all mortal and venial sins under the Ten Commandments for the use of lay Christians. It was printed in Granada by Meinardo Ungut around 1496 as part of Talavera's pastoral programme for the reform of Castilian Christian life, making it among the earliest vernacular aids to sacramental confession produced in Spain. The Decalogue-based structure shaped the catechetical approach of the Isabelline court and its chaplains, and the text was apparently used in the instruction of court members and newly converted populations alike. Its practical, exhaustive schema of sins represents a democratisation of the confessor's art that had previously been reserved for the clergy.
Tratado que significa las ceremonias de la misa
Tractado llamado breue forma de confesar y lo que significa las cerimonias de la missa
A vernacular treatise by Isabella's confessor Hernando de Talavera explaining the meaning of every ceremony and gesture of the Mass in accessible Castilian, composed for the formation of lay nobility, court members, and the queen's household. Talavera used this work to shape affective devotional practice by ensuring that members of Isabella's court understood not merely how to attend Mass but how to participate interiorly in each rite—an approach documented in scholarship on his strategy of vernacular catechesis. The work is a pivotal example of Isabelline popular theology: making the Latin liturgy intelligible and devotionally productive for lay royalty and their households. Its pastoral method anticipates by eighty years the liturgical catechesis that the Council of Trent would mandate for the universal Church.
Imitatio Christi (early Castilian translation)
De Imitatione Christi / Menosprecio del mundo
The Imitation of Christ, composed by Thomas à Kempis c. 1418–1427, was among the most transcribed books of the later Middle Ages after the Bible; a Castilian translation circulated by c. 1490, the height of Isabella's reforming programme, reaching Hieronymite and Franciscan houses she actively patronised. Its four books—on interior conversion, the spiritual life, interior consolation, and the Eucharist—formed the core of lay and religious formation in exactly the devotional idiom promoted by Talavera at Isabella's court. Though no personal copy is confirmed in Isabella's inventory, the Castilian translation circulated throughout the Hieronymite communities she endowed and embodied the Devotio Moderna spirituality that Cardinal Cisneros championed. It subsequently became one of the most printed books in the history of Christianity.
