recent technical analysis, Verrocchio began this altarpiece around 1468, which was then put aside for some years before Leonardo reworked portions of the painting's surface in the 1470s. Provenance The painting was at some point transferred from the Church of San Salvi to the Vallombrosan Sisterhood in Santa Verdiana. In 1810, it entered the collection of the Accademia and passed to the Uffizi in 1959.
