Taddeo Crivelli is now conserved in the Biblioteca Estense in Modena.
Crivelli is known to have completed other major works in Ferrara, at least two of which survive. 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 sumptuous book of hours, known as the Gualenghi-d'Este Hours, produced some time after the marriage in 1469 of Orsina D'Este with Andrea Gualengo (another prominent advisor to Borso), is conserved in the Getty Museum.
Although he may have produced larger paintings while in Ferrara,[n 2] none has been found. 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.
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 also took on the unfamiliar task of engraving maps and nautical charts, and is usually accepted as the engraver of the 1477 Bolognese edition of Ptolemy's Cosmographia, the first book both to contain printed maps and to be illustrated by engravings rather than woodcuts. A slightly later map of the world on a single sheet has also been attributed to him, but is now not thought to be his. Receipts show that in this period payments for his illuminations declined. 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). His last recorded work dates from 1476; by 1479 he is referred to as being dead.
His wife Margherita bore him three sons and a daughter, Lodovica, who married the painter Lorenzo Costa.
The style of the art-work in the Borso Bible has been linked to the Ferrara school of painting which developed under the influence of Cosmè Tura (and especially to the frescoes that were subsequently painted to decorate the Salone dei mesi in Palazzo Schifanoia). Some of Crivelli's stylistic traits, such as his use of line in representations of clothing and clouds, also suggest Lombard influence. The elaborately decorated miniatures for the Borso Bible are characterized by saturated colouring and rich costumes that would seem to comply with Borso's luxurious tastes. Architectural spaces are rendered by means of false perspective.
