( fl c. 1385–c. 1390). Italian illuminator. The leading illuminator in Pavia before Michelino da Besozzo, he painted a self-portrait and an inscription, frater Petrus de Papie me fecit 1389 in an initial of Pliny’s Natural History (Milan, Bib. Ambrosiana, MS. E. 24. inf., fol. 332r). The initial opens chapter 35, ‘On Painting’, and the self-portrait shows him as an Augustinian friar at work on the manuscript. Pietro was presumably a member of the Pavian convent of the Augustinian hermits of S Pietro in Ciel d’Oro. This manuscript and several others illuminated in the same style, including Pietro d’Abano’s Commentary on Aristotle’s Problems and Petrarch’s Res memorandae (both Paris, Bib. N., MSS lat. 6541 and 6069T), were made for Pasquino Capelli (d 1390), the humanist who was secretary to Giangaleazzo Visconti, ruler of Milan. The earliest dated manuscript with decoration in Pietro’s customary style, Caesar’s Conquest of Gaul (Leiden, Bib. Rijksuniv., MS. BPL 16A), was written in 1385, and much of Pietro’s surviving work must have been completed before Pasquino’s execution for treason in 1390.
