Church of Saint Agatha

Letter 4,19 - to Leo, acolyte. March 594

(Thus) the church of Saint Agatha, situated in Subura, that was once a cave of heretical depravity, has been brought back to the worship of the Catholic faith, by the grace of God. For that reason, armed with the direction of this authority, continue to collect each year the taxes on all the houses built in this city that the aforesaid church is agreed to have hand in the time of the Goths.
However much is necessary for repairing buildings or for lamps, and for other restoration of that church, you must be keen to pay in full. But whatever might be left over, we order you to credit it honestly to the Church accounts.
