 On the lower left are the Renaissance humanists, including Cristoforo Landino (the one with a black collar) and Agnolo Poliziano (the second from right).The figures standing on the right are relatives of the patron; behind them is a self-portrait of Ghirlandaio (the second from right, next to a youngster with long hair, probably his son or brother, who is also present in the "Expulsion of Joachim").The inscription on the arch at the left celebrates the completion of the cycle (in 1490), and has a quote by Agnolo Poliziano.
