XXXVII. Trajan to Pliny
AS my freedman Maximus was going upon an extraordinary commission to procure corn, I approve of your having supplied him with a file of soldiers. But when he shall return to the duties of his former post, I think two from you and as many from his coadjutor, my receiver-general Virdius Gemellinus, will be sufficient.
