F͞RM and FA͞ML aright, this inscription would imply that members of each of the three grades of the Roman Masonic guild, Magister, Fratres, and Famuli (apprentices), were martyred together, and their remains placed in this church with the relics of some proto-martyrs. The _Magistri_ were afterwards canonized, and the four I have named became the patron saints of the guild. S. Carpophorus was held in special veneration in Como, of which place he was probably a native, or else a Greek member of the Comacine Lodge there. The other side of the inscription chronicles the restoration of the altar which was ruined and broken down, in the time of Pope Paschalis Secundus, A.D. 1111, in the fourth Indiction. The church of the SS. Quattro has remains of a fine atrium or portico. In the wall of the atrium is a fragment of _intreccio_. The original form of the church is well preserved, and is identical with that of S. Agnese, _fuori le mura_. The gallery for the women is well preserved. The especial veneration for the four crowned martyrs seems to point to their Roman origin, and to specify the reason why the remnant of the particular _Collegium_ to which they belonged fled from Rome, and took refuge in the safe little republic of Como, so that it was not only the Goths and Vandals from whom they fled. It explains also the intense religion in their work, and rules; the very first principles of which were to respect God's name, and do all to His glory.
