John of Cremona
FlourishedToledo, Spain, second half of the thirteenth century
John of Cremona was one of the scholars who worked under Alfonso X’s patronage in Toledo, where he aided John of Messina in the revision of the Los IIII Libros de la Ochava Espera in 1276. E. S. Procter identified him with the chancery clerk “Magister Johannes de Cremona” who on 23 March 1284 signed the letter of Alfonso X, in which the dying king informed Pope Martin IV of his reconciliation to his rebel son. After Alfonso’s death, Johannes de Cremona remained in the royal service, and his name occurs in the household accounts of Sancho IV for 1293–1294.
