Interesting hybrid miscellany of scientific and historical texts, combining two incunables and one manuscript together in a single codex. The two incunables are treatises on lunar and solar cycles, both quite rare, and the second one illustrated. The third part of the miscellany contains a near-complete copy—one of five known (the others in European collections)—of a Catalan translation of the Liber destructionis Ierusalem. This vernacular manuscript provides a crucial link to vernacular culture and crusade mythology in the later Middle Ages.

Bernat de Granollachs (d. 1487?) was born in the first half of the fifteenth-century to an important but minor noble family dedicated to medicine in Barcelona.  He studied medicine at Barcelona then received his master’s in Montpellier, where he travelled in 1440. Returning to Barcelona, he became noted for his astronomical studies among the local elite. His most famous work, the Lunarium ab anno 1491 ad annum 1550, consists of an important set of charts calculating the phases of the moon, including eclipses and movable feasts, from 1491 to 1550.  The difficulty in calculating the solar and lunar calendars led to the popularity of Granollachs’ work, especially given the importance of movable religious feast days like Easter and for novice astronomers. The first printed Lunari appeared in Catalan circa 1485 in Naples, followed by translations into Italian and Latin and Castilian. The utility of the charts quickly led the Lunarium to becomeone the most published texts (42 incunabula editions in five languages) at the end of the Middle Ages. Other authors seized on its popularity, and copied his tables verbatim into their own works, such as the almanac produced by Andrés de Li known as the Repertorio de los tiempos. Ironically, Granollachs’ work was not original, but copied the erudite Jewish astronomer Jacob ben David Bonjorn of Girona (b. 1333). Bonjorn, who served as one of the royal astronomers of King Pere el Ceremoniós of Aragón, created the set of tables for the city of Perpignan that calculated the true syzygies (conjunctions and oppositions of the sun and the moon) for 31 years starting in 1361. Bonjorn’s own work, later translated into Latin, Catalan, and Greek, was in turn based on the writings of Levin ben Gerson (d. 1344). 

The present edition printed by the Swiss printer Johannes Siber was one of three editions that he completed at Lyons in 1491 (ISTC ig00340500; GW 11312). This is one of only two known exemplars of the 1491 Siber edition that survive, the other being at St. Andrews University Library.    

Very little is known about Master Anianus. Scholars believe that he was a French Benedictine monk, likely living at the monastery of Aniane near Montpellier during the second half of the thirteenth century. Anianus’s Computus cum commento attempted to make the difficult calculations of the lunar and solar calendars more accessible for those who needed to understand them for church festivals and calendars by simplify the mathematics into mnemonic verse. He also designed a memory system using the digits on the hand to help make the mathematical calculations more accessible to novice scholars. His work therefore does not rely on complex algorithms, but instead on calculating devices using the joints of the hand and the different spaces on the palm.  Beginning in 1485, the large number of illustrated editions of Anianus’s book demonstrates its popularity and importance for calculating the calendar. Jean du Pré, the publisher of this edition, was a well-known and productive printer in Paris, who periodically moved his press to regional centers such as Lyons and Nantes to increase his profits and expand his business interests. 

This copy of du Pré’s 1490 edition (ISTC ia00736500; GW 1958) is the last of three editions published by the Lyonese printer, the first being in 1488.  It is one of six other known exemplars of this edition, all located in Europe. 

The Liber destructionis Ierusalem, also known by its French title La vengeance de nostre Seigneur, is an apocryphal history of the destruction of Jerusalem under the Flavians. The medieval version changes Roman history from one of political and military retribution for revolting against the Empire, to one of punishing the Jews for the crucifixion of Jesus Christ. For the transformation to take place, medieval writers concocted a story describing the miraculous cure of Vespasian by a relic of Christ. This miraculous cure led Vespasian to punish the Jews for their treatment of the founder of Christianity after the saint had visited Rome and preached to the people. Although earlier stories of the destruction of Jerusalem circulated in Latin in Europe as the Gesta Pilati or Vindicta Salvatoris, the Catalan variation derives primarily from the later fourteenth- and fifteenth-century French prose versions derived from the original twelfth-century poem. The prose version proved highly popular in Europe, being translated into Provencal, Catalan, Castilian, and Portuguese. The popularity of the text led it to be printed three times in the Iberian Peninsula during the 1490s, but not in Catalan. This manuscript is one of five known copies of the Liber destuctionis Ierusalem in Catalan, two being held in the Biblioteca de Catalunya (MS 710 and 991), one in the Arxiu de la Corona d’Aragó (MS Ripoll 155), and one in the Paris, BnF (MS esp. 509).
