Giovanni de' Bardi and Sandro Botticelli in Santo Spirito.

'Examines the altarpiece of the "Madonna and Child with two saints John", commissioned by de' Bardi for his chapel in the church of S. Spirito, Florence, in 1483. Studies the painting's patronage and context in the light of visual, theological, and extensive documentary evidence, proposing that the painting's meaning and subject (the Virgin seated in the garden of paradise) is completed only in the presence of the spectator' (BHA).
