Sainte Catherine, saint Antoine de Padoue, saint Jean l'Évangéliste (au-dessus : Isaïe)

Neri di Bicci's panel of Saints Catherine, Anthony of Padua, and John the Evangelist with Isaiah above (1465) represents a mid-career commission typical of his Florentine workshop operation. The combination of Catherine (martyr and patroness of scholars), Anthony of Padua (Franciscan wonder-worker), and John the Evangelist (apocalyptic visionary) alongside the Old Testament prophet Isaiah suggests a commission from a confraternity or institution that maintained multiple devotional allegiances. Isaiah's presence above the saints — as a typological figure whose prophecies were read as predicting Christ — was common in Northern Italian painting but relatively uncommon in Florentine altarpieces of this period.

Neri organizes the three saints in a shallow horizontal band typical of his multi-figure panels, with Isaiah in a separate zone above as a typological register. Individual saints are identified by attributes: Catherine's palm and wheel, Anthony's lily and book, John's chalice with emerging serpent. The palette is characteristically saturated with the warm-cool contrasts Neri deployed efficiently across his large workshop output. Execution is confident and professional with no excessive refinement.
