"Annunciation with St. Margaret and St. Ansanus"

The central panel is considered one of Martini’s masterworks, showing his innovative use of line combined with a sense of movement and human expression. The angel’s gown flares behind him as if he has just landed, and the Virgin seems to recoil, her face disbelieving at his announcement. Though the setting, employing extensive gold, and subject reflect Byzantine tradition, the portrayal of the Annunciation as a dramatic moment was unique in its time.

The prodigious use of gold leaf, lapis lazuli, and expensive lacquer, indicate the high status of this altarpiece, commissioned by the Cathedral of Siena, and dedicated to the city’s patron saints. Some scholars credit Lippo Memmi with the depiction of St. Margaret, on the far right, though other scholars also attribute to him the portrayals of St. Ansanus on the left and the prophets, Jeremiah, Ezekiel, Isaiah, and Daniel, in the tondos, or circular paintings. However, Memmi’s depictions lack the sophistication of Martini’s approach.
