Meanwhile the ancient state of Lavo (Lopburi), with its capital at Sano (Sornau or Shahr-i-nao), at one time feudatory to Swankalok-Sukhotai, remained the last stronghold of the Khmer, although even here' the race was much modified by Lao-Tai blood; but presently Sano also was attacked, and its fall completed the ascendancy of the Siamese (Thai) throughout the country.
In the 15th century we have Domenico di Bartolo, Sano di Pietro, Giovanni di Paolo, Stefano di Giovanni (Il Sassetta) and Matteo and Benvenuto di Giovanni Bartoli, who fell, however, behind their contemporaries elsewhere, and made indeed but little progress.
Maria di Provenzano, a vast baroque building of some elegance, designed by Schifardini (1594) Sant' Agostino, rebuilt by Vanvitelli in 1755, containing a Crucifixion and Saints by Perugino, a Massacre of the Innocents by Matteo di Giovanni, the Coming of the Magi by Sodoma, and a St Anthony by Spagnoletto (?); the beautiful church of the Servites (15th century), which contains another Massacre of the Innocents by Matteo di Giovanni and other good examples of the Sienese school; San Francesco, designed by Agostino and Agnolo about 1326, and now restored, which once possessed many fine paintings by Duccio Buoninsegna, Lorenzetti, Sodoma and Beccafumi, some of which perished in the great fire of 1655; San Domenico, a fine 13th-century building with a single nave and transept, containing Sodoma's splendid fresco the Swoon of St Catherine, the Madonna of Guido da Siena, 1281, and a crucifix by Sano di Pietro.
The atrium has a fresco by Bartolo di Fredi and the two ground-floor halls contain a Coronation of the Virgin by Sano di Pietro and a splendid Resurrection by Sodoma.
