The Legend of Brutus and Portia

The Legend of Brutus and Portia of around 1485, now in the Fine Arts Museums of San Francisco, belongs to the category of secular narrative panel painting — spalliera or cassone panels — that provided Florentine workshop painters an opportunity to explore classical Roman history as pictorial subject matter. The story of Brutus and his wife Portia, who swallowed burning coals to demonstrate she could endure the same pain as her husband, was valued as an example of feminine virtue and conjugal solidarity. Such classical virtue narratives were standard equipment in the decorative programs of aristocratic and merchant-class Florentine households of the later fifteenth century.

The horizontal frieze format typical of spalliera painting places the narrative's key moments across the canvas in sequential order, requiring a compositional approach different from the centralised devotional subjects that dominated Sellaio's other work. Figure scale and architectural staging are calibrated to the decorative domestic context rather than the intimate devotional one.
