Rome is almost as full of remains of what is now styled Comacine architecture, as it is of classic and pagan ruins, and they are nearly as deeply buried. Go where you will, and in the vestibules or crypts of churches, now of gaudy Renaissance style, you will find the sign and seal of the ancient guild. Investigate any church which has a Lombard tower--and they are many--and you will discover that the hands which built that many-windowed tower have left their mark on the church. In that wonderful third-century basilica, which was discovered beneath the thirteenth-century one of S. Clemente; in the almost subterranean basilica of _S. Agnese fuori le mura_; in the vestibule of the florid modern SS. Apostoli; in Santa Maria in Cosmedin; and various other buildings, are wonderful old slabs of marble with complicated Comacine knots on them. Our illustration is from a slab in San Clemente, which was evidently from the buried church, though used as a panel in the parapet of the existing choir. A marvellous piece of basket-work in marble, which, if studied, will be found composed of a single cord, twined and intertwined. An almost identical panel is preserved in the wall of the staircase to S. Agnese, another has just been found reversed, and the back of it used for the thirteenth-century mosaic decoration of the pulpit in S. Maria in Cosmedin. Then in the later Lombard churches of S. Lorenzo in Lucina, SS. Giovanni e Paolo, S. John Lateran, etc., one may see the crouching Comacine lions, now mostly minus their pillars, and shoved under square door-lintels, or built into walls, where they remain to tell of the ancient builders whose sign and seal they were. And here and there we get a name. In the vestibule of the SS. Apostoli is a red marble lion, on the base of which in Gothic letters is the name BASSALECTI. Beneath it is an old inscription, "Opus magister Bassalecti Marmorari Romano sec, XIII." This same Magister's name, spelt _Vassalecti_, has lately been discovered inscribed on the capitals of some columns in the nave of S. John Lateran. In the under church of S. Clemente, an ancient fresco of the eighth century takes us further back than this. Here we see a veritable Roman _Magister_ directing his men. He stands in magisterial toga (and surely one may descry a masonic apron beneath it!), directing his men in the moving of a marble column, and with the naïve simplicity of the primitive artist each man's name is written beside him. Albertel and Cosmaris are dragging up the column with a rope, the sons of Pute, who are possibly novices, are helping them, while Carvoncelle is lifting it from behind with a lever. These men are all in short jerkins, but the master, Sisinius, is standing in his toga, directing them with outstretched hand.
