The Annunciation with Saint Francis and Saint Louis of Toulouse [four panels]

Cosmè Tura's Annunciation with Saint Francis and Saint Louis of Toulouse is one of the most important surviving works by the founder of the Ferrarese school, executed around 1470 to 1480 when Tura was court painter to the Este family in Ferrara. The polyptych format — four panels combining the Annunciation with flanking saints — follows established altarpiece conventions, but Tura transforms the iconography through his extraordinarily personal style: angular, almost anguished forms, bizarre architectural fantasy, and a palette of startling jeweled intensity. Saint Louis of Toulouse was a Franciscan friar who became bishop and briefly king of Naples before his early death, making him an unusual choice for this pairing. The Este court's sophisticated culture produced in Tura one of the most distinctive visual imaginations of the Italian fifteenth century, and this work encapsulates his contribution to the Early Renaissance.

Tura's distinctive style — angular, crystalline, and intensely colored — is fully realized in these panels. Forms are built with hard, precise contours and metallic surface quality. The palette is extraordinary: deep lapis blues, crimson, gold, and green create an almost enamel-like richness. Architectural backgrounds combine Gothic fantasy with classical elements in Tura's personal synthesis.
