Taddeo Crivelli

Analysis of his personal account book between 1451 and 1457 alongside official court documents indicates that Crivelli was in charge of a busy workshop, sharing work out with assistants and colleagues.

[6] Other painters who assisted Crivelli and Russi on the illuminations include Guglielmo Giraldi, Giorgio D'Allemagna and a youthful Girolamo da Cremona.

[4] Production of the Bible cost exactly twice the amount paid to Domenico Ghirlandaio for the entire Tornabuoni Chapel in Santa Maria Novella in Florence.

A 1467 illuminated copy of Boccaccio’s Decameron, which was commissioned for Teofilo Calcagnini, a court advisor to Borso, is conserved in the Bodleian Library in Oxford.

A record of a pawnbroking transaction of 1472 suggests that he may have left Ferrara abruptly, presumably in the wake of Borso's death in 1471, and perhaps attracted by the patronage of the Bentivoglio family in Bologna.

[3][6] By 1473 Crivelli was working in Bologna with a fellow miniaturist, Domenico Pagliarolo (fl 1471–97), on a Gradual for the monastery of San Procolo.

He was engaged to work on manuscripts for the grand basilica of San Petronio, but ended up pawning parts of them (which his patrons later bought back).
