The Ascent of Mount Sion (Subida del Monte Sión)
Después de haber considerado los misterios de Cristo, reposa el alma en silencio ante Dios.
Our renderingAfter having contemplated the mysteries of Christ, the soul rests in silence before God.
What it is
A foundational Spanish mystical treatise on recogimiento and the prayer of quiet by Franciscan friar and court physician Bernardino de Laredo, containing the first written description of the prayer of quiet in the Spanish tradition. Teresa of Avila, writing in her Life (chapter 23), credits the Ascent as the work that resolved her perplexity about her supernatural experiences and named it one of the books she consulted throughout her life. Laredo served as physician to King John III of Portugal and Queen Catherine of Austria, sister of Charles V, giving him documented access to the Habsburg devotional network. The revised third book of 1538 is the influential text that passed into the Carmelite and Franciscan mystical inheritance.
Why it still matters
The third book's description of the prayer of quiet — ceasing active meditation to rest in wordless attention before God — is the clearest early guide in Spanish to what is now called contemplative or centring prayer, and it remains a practical transition manual for anyone moving beyond discursive meditation.
Kept alongside
The Life (Libro de la Vida) of Teresa of Ávila
The spiritual autobiography of Teresa of Ávila, weaving a candid account of her inner conversion with a systematic treatise on the four degrees of prayer she famously described through the imagery of four ways of watering a garden. Philip II personally requested the autograph manuscript for the Escorial library in 1592; it was delivered by Diego de Yepes—Teresa's former confessor and later Philip's own—and is preserved at the Real Biblioteca del Monasterio de El Escorial (shelfmark Vitrina 26) to this day. Philip also used royal influence in 1579 to secure autonomous jurisdiction for Teresa's Discalced Carmelite reform and shielded her writings from sustained Inquisition proceedings.
Spiritual Exercises (Exercitia Spiritualia)
The foundational Jesuit method of prayer and discernment composed by the Spanish-Basque Ignatius of Loyola, structuring a four-week guided retreat through meditations on sin, the life of Christ, the Passion, and the Resurrection. Its Habsburg connection runs deep: Joanna of Austria (1535–1573), daughter of Charles V and sister of Philip II, was secretly admitted to the Society of Jesus under the alias 'Mateo Sánchez' after undertaking the Exercises under the direction of Francis Borgia, former Duke of Gandia and a close Habsburg courtier—making her the only woman ever enrolled in the Jesuit order. Philip II was unaware of his sister's membership, yet the Ignatian network shaped the spiritual climate of the court from within.
The Way of Perfection (Camino de Perfección)
Teresa of Ávila's practical guide to communal and personal prayer, written for the first nuns of her Discalced Carmelite reform and centred on mental prayer, recollection, detachment, and a celebrated extended commentary on the Our Father. Philip II acquired this autograph for the Escorial library, where it survives in the Real Biblioteca alongside her other manuscripts, giving the text royal sanction and ensuring its early preservation and wide circulation. The book's pedagogical clarity made it a formation text not only for nuns but for literate lay readers across the Spanish Empire.
