Андреа Верроккьо
Following Gustav Waagen methods in 1869, Baron Liphart identified this "Annunciation", that newly arrived in the Uffizi Gallery from the church of San Bartolomeo a Monte Oliveto in Florence, as by the young Leonardo while he still was working in the studio of his master, Andrea del Verrocchio. Before that determination by Liphart the painting had been attributed to Domenico Ghirlandaio.
