knight with flowing golden hair, the miraculous sword forming on the rocky desert place the sacred sign of Redemption. Simone Martini is not represented in the Gallery; but there is an altarpiece (51) ascribed to Lippo Memmi, and fairly characteristic of the religious art of fourteenth century Siena. A well-preserved picture in the following room (11), with St Michael as central figure, shows something of Lippo's manner, but is not a work of the master himself. In the second room there is a noble collection of paintings by the Lorenzetti. By the elder brother Pietro are: the Assumption of the Madonna (5), with the doubting Thomas receiving the sacred girdle; the Madonna and Child enthroned (21), with a lovely band of Angels clustering round the throne; four small scenes from the history of the Order of the Carmelities (28, 29), being apparently the remains of the predella of a famous picture that Pietro painted for the church of the Carmine in 1329. The younger Lorenzetti, Ambrogio, is represented by three masterpieces. The smallest of these (9) is a perfect gem of early Sienese art; the Madonna is enthroned with both her arms folded round the Divine Child, who unfolds a scroll to the four Latin Doctors kneeling in adoration, each receiving His doctrine with a wonderful expression of rapt devotion, ecstasy and yearning--but each in a totally different way; the golden haired Virgin Martyrs, Catherine with her wheel, Dorothy with her flowers, are standing in attendance on the Queen, and there are six adoring Angels above. The large altar-piece (2) is a striking and imposing work; the Madonna and Child are attended by the Magdalene and St Dorothy and the two St Johns, while below is the Deposition from the Cross: the heads are full of beauty and expression, and the Deposition shows Ambrogio's dramatic power. The Annunciation (33), dated the 17th of December 1344, appears to be Ambrogio's last extant work; it was painted for the Palazzo del Comune and, in addition to the painter's name, is inscribed with those of the Camarlingo--Don Francesco, monk of St Galganus--the three Esecutori and the Scrittore or scribe.[63] High up on the wall above this picture are two half figures of saints (34, 36), damaged, but genuine Ambrogios. Ascribed to Pietro Lorenzetti is a curious allegory (37), apparently of the story of sin and the Atonement of the Cross.
