Pere Joan was a beneficed priest at the church of Sta Maria del Mar who appears to have lived in the house owned by the church for its priests, 'la casa del longo'. Joan owned a good collection of books, may of them religious or devotional, such as the Bible, books of hours, breviaries, collections of sermons, but he also owned a number of titles by Ramón Llull and works by classical authors such as Aesop, Juvenal, Aristotle, Tully and Ovid (Metamorphoses). This collection was kept in the dining-room of the house. He also had a few books in the room in which he died, as well as a retable of the Descent from the Cross, and in an upstairs room overlooking the sea a few more books, including Ovid's Letters, Nebrija's grammar and a 'libre de cant' with vellum covers ('Item altre libre de cubertes de pregami de cant'). 

Another inventory was begun on Friday 21 April 1536, but it is clearly incomplete, and none of the books are listed. A later inventory, dated 9 August 1536, includes the books, and including the music book which, if a reference to the 'libre de cant' in the post-mortem inventory was in fact a book of chant ('Item dos libres nomenats hu de cant pla laltro scrit de ma'). It's not clear what the identity of this second book might be. They were worth little, and sold for 1s to an unidentified (because illegible) purchaser. A Roman breviary was sold to mossen Luch Scot for 6d, and  a Valencian psalter ('saltiri ab lo bisbe de valencia') to Jaume Fonolleda for 7s. The copy of Aesop's fables was sold for 6s 3d to one of the executors.
