ACQUA MARCIA.
I sha'n't forget, on the long bleak road from Subiaco to Vicovaro, a violent dry wind against us, veiling all things in dust, a spring near Spiagge: a wide runnel of water spirting out of the travertine and running off into clear rills where the mules drink. The water they collect up here for the Acqua Marcia, whose aqueducts we see about, old arches and new; water, cold, infinitely pure, exquisite, one might say almost fragrant. It was such spirts from the rock, as well as the sight of pure mountain streams, which taught St. Francis his verse about Suor Acqua. St. Francis must have wandered in these fastnesses which (totally unlike the country between Segni and Olevano) are very Umbrian in character. There is a portrait of him, said to be by a contemporary monk, on a pilaster of one of the subterranean chapels of the Sacro Speco above Subiaco: blond, wide-eyed, the cowl drawn over his head.

THE SACRO SPECO.
The Sacro Speco was a very charming surprise. The series of little churches and chapels up and down flights of steps, vaulted and painted in Gothic style, with shrine lamps here and there, were quite open and empty. We walked into them, or rather into a crooked vestibule frescoed by some Umbrian, with no sudden transition from the splendid grove of ilexes, immense branches like beams overhead, from the great hillside of bluish-grey tufo, with only a few bitter herbs on it. The convent of the Sacro Speco is a half-fortified little place into which we could not penetrate. Only a surly monk, found with difficulty (another entered the chapels with a great bundle of wall-flowers and irises), took us into the microscopic garden under the convent battlements hedged with flowering rosemary, where the roses in which St. Benedict rolled are grown (May roses, only bright leaves as yet) literally in the shape of a bed or gridiron, row along row.
Though it is not remote-looking, 'tis a splendid place for a hermit's thoughts: the blue-grey hillside running down into the green rushing Anio, the great bare bluish mountains all round, far enough to be visible, a great sense of air and space, for a valley. No vegetation, save a few olives and scrub oaks and the bitter herbs and euphorbus. No scented happy Tuscan things. And deep below, the arches of Nero's Villa—with demons no doubt galore. Those giottesque chapels hold in them, all hung with lamps, a small tufo grotto, the one down which, as in Sodoma's fresco, the angels sent baskets of provisions and the devils made horns at St. Benedict.
