What it is
Now in the Royal Collection at Windsor Castle (RCIN 1142248), the Sobieski Hours was made in Paris c. 1420–1430, possibly for Margaret of Burgundy, oldest sister of Philip the Good and daughter of John the Fearless, and possibly as a wedding gift for her 1423 marriage to Arthur III, Duke of Brittany. It passed to the Polish King John III Sobieski and through his granddaughter Maria Clementina Sobieska to James Stuart (the Old Pretender); his descendant Henry Benedict Stuart, Cardinal York, bequeathed it to the future King George IV, through whom it entered the British Royal Collection. Its extraordinary dynastic journey across Catholic royal houses — Burgundian, Polish, and Stuart — over two centuries is fully documented in Eleanor P. Spencer's scholarly monograph (Academic Press, 1977). The manuscript stands as a remarkable witness to the role of the personal prayer book in sustaining Catholic identity across political exile and dynastic upheaval.
Why it still matters
The Sobieski Hours illustrates how a single Book of Hours could anchor a family's faith and identity across generations of exile and dynastic displacement; a Christian today can take from it the practice of treating one prayer book as a lifelong, family-linked companion to daily prayer.

Psalter (for the Education of Giovanni de' Medici)
The documented use of the Latin Psalter as the basis of young Giovanni de' Medici's religious instruction by his mother Clarice Orsini is one of the most precisely attested Medici devotional education episodes. When Poliziano attempted to teach the Medici boys using Homer and classical authors, Clarice expelled him from the villa at Cafaggiolo (c. 1479) and substituted the Latin Psalter, insisting on traditional Catholic instruction. Giovanni later became Pope Leo X, giving the episode retrospective significance; it is documented through Poliziano's own letters and subsequent Renaissance scholarship. The underlying text — the Psalter itself — was the universal prayer book of medieval and Renaissance Christendom and carries the highest possible devotional relevance independent of this particular episode.
English Primer (The Prymer)
Prymer or Lay Folks' Prayer Book
The English Primer ('Prymer') was the standard lay devotional book in England from the 14th to 16th centuries, used by children and adults alike to learn both literacy and prayer. Beginning as a first reading book combining the alphabet, Pater Noster, Ave Maria, and Creed, it grew to include the Little Office of the Blessed Virgin Mary, the Seven Penitential Psalms, the Fifteen Gradual Psalms, the Litany of the Saints, and the Office of the Dead. Chaucer's reference in the Prioress's Tale (c. 1386) to a seven-year-old boy learning his 'primer' confirms its role in children's formation, and Eleanor of Castile purchased 'seven primers' in Cambridge in 1289 for royal household use. The royal culmination was Henry VIII's King's Primer (1545), principally compiled by Archbishop Cranmer and prescribed by royal proclamation as the only permitted primer in England.
Très Riches Heures du Duc de Berry
Commissioned c. 1412 by Jean de France, Duc de Berry — son of King John II and brother of Charles V — this is the supreme surviving example of Valois private devotion in manuscript form. It contains the canonical hours structured around the Hours of the Virgin, Hours of the Cross, Hours of the Holy Ghost, Penitential Psalms, Office of the Dead, and additional offices and masses, all framed by the famous calendar illuminations depicting the labours of the months. The duke used it for daily private prayer in his châteaux, and it was left unfinished at his death in 1416, completed only in 1485–1489 by Jean Colombe for Charles I of Savoy. Its unmatched luxury simultaneously signals sincere personal piety and the Valois use of devotional objects as instruments of dynastic prestige.
