Fra Lorenzo was officiating at the altar as they entered the large church, before a small number of peasants, the women making a picturesque group in their light flowered bodices and their red petticoats visible from beneath their tucked-up gowns, and their gay cotton handkerchiefs knotted about their heads, since no woman's head may be uncovered in the Catholic Church. The padre came soon to escort them about the church, and "to show them what little had been left," he said, pointing to the empty chapels. They found enough, however, to fill them with admiration in dear, good Fra Giovanni of Verona's marqueterie-work in the backs of the stalls, which extended the whole length of the long church, as is customary in monasteries where the monks are the sole participants at the holy offices. "While Fra Giovanni was here as one of our order," the padre explained, "he finished the stalls which are now in the cathedral of Siena. They were taken from us in 1813. After we were allowed to come back, we asked to have our stalls replaced by those in a monastery in Siena which was being torn down, and so these stalls were sent us: they are by Fra Giovanni's own hand. He has never been equalled in this kind of work, for which he invented the staining of the woods to produce light and shade, and perfected the perspective which Brunelleschi invented while resting from his labors on the Florentine dome. The different Italian cities on the hill-sides, the vistas down the long streets, with palaces and churches on either side, half-open missals, Biblical musical instruments, rolls of manuscript music, birds in gay plumage, all perfectly represented in minute pieces of wood, excite the wonder of every one whose privilege it is to examine them at leisure."
