XXVII. To the Emperor Trajan
YOUR freedman and procurator,1 Maximus, behaved, Sir, during all the time we were together, with great probity, attention, and diligence; as one strongly attached to your interest, and strictly observant of discipline. This testimony I willingly give him; and I give it with all the fidelity I owe you.
