We retrace our steps through the Porta Camollia to the Lizza, that favourite promenade of the Sienese which now covers the site of Don Diego's citadel, where the nightingales are loud at evening among the trees at the entrance to Santa Barbara, the Medicean fortress of Duke Cosimo thrown open to the citizens by an Austrian Grand Duke. The church of San Stefano, on the Lizza, contains over the high altar the masterpiece of St Catherine's painter disciple, the reformer Andrea di Vanni, painted about 1400. It is a typical Sienese picture, but of no surpassing merit; the Madonna and Child are enthroned in the central panel, with the Annunciation above; at the sides are the Baptist and St Bartholomew, St Stephen and St James, with the four Evangelists above them and other saints in the _cuspidi_ and pinnacles. The faces of the virgin martyrs have something of the characteristic Sienese gentle sweetness. The predella is obviously later, being probably the work of Giovanni di Paolo.
