which lamps were placed, without which, indeed, the Catacombs must have been an impenetrable labyrinth. Cardinal Wiseman recounts a touching legend of a young girl who was employed as a guide to the places of worship in the Catacombs because, on account of her blindness, their sombre avenues were as familiar to her accustomed feet as the streets of Rome to others.

Both sides of the corridors are thickly lined with loculi or graves, which have somewhat the appearance of berths in a ship, or of the shelves in a grocer’s shop; but the contents are the bones and ashes of the dead, and for labels we have their epitaphs. [Figure 4] will illustrate the general character of these galleries and loculi.

The following engraving, after a sketch by Maitland, shows a gallery wider and more rudely excavated. On the right hand is seen a passage blocked up with stones, as was frequently done, to prevent accident. The daylight is seen pouring in at the further end of the gallery, as described by Prudentius,[9] and rendering visible the rifled graves.

It is evident that the principle followed in the formation of these galleries and loculi was the securing of the greatest amount of space for graves with the least excavation. Hence the passages are made as narrow as possible. The graves are also as close together as the friable nature of the tufa will permit, and are made to suit the shape of the body, narrow at the feet, broader at the shoulders, and often with a semi-circular excavation for the head, so as to avoid any superfluous removal of tufa. Sometimes the loculi were made large enough to hold two, three, or even four bodies, which were often

placed with the head of one toward the feet of the other, in order to economize space. These were called bisomi, trisomi, and quadrisomi, respectively. The graves were apparently made as required, probably with the corpse lying beside them, as some unexcavated spaces have been observed traced in outline with chalk or paint upon the walls. Almost every inch of available space is occupied, and sometimes, though rarely, graves are

dug in the floor. The loculi are of all sizes, from that of the infant of an hour to that of an adult man. But here, as in every place of burial, the vast preponderance of children’s graves is striking. How many blighted buds there are for every full-blown flower or ripened fruit!

Sometimes the loculi were excavated with mathematical precision. An example occurs in the Cemetery of St. Cyriaca, where at one end of a gallery is a tier of eight small graves for infants, then eight, somewhat larger, for children from about seven to twelve, then seven more, apparently for adult females, and lastly, a tier of six for full-grown men, occupying the entire height of the wall. Generally, however, a less regular arrangement was observed, and the graves of the young and old were intermixed, without any definite order.
