DXVI (F XIII, 23)
TO SERVIUS SULPICIUS RUFUS (IN ACHAIA)I am very intimate with L. Cossinius, your friend and fellow tribesman. For not only is there a long-standing acquaintance between us personally, but my friend Atticus has caused my relations with Cossinius to become still closer. Accordingly, the whole family of Cossinius is attached to me, and especially his freedman L. Cossinius Anchialus, a man who possesses the high esteem both of his patron and his patron's friends, of whom I am one. I recommend him to you as I would a freedman of my own, and as though he held the same position with me as he does with his patron. If he did I could not recommend him with greater warmth. Wherefore you will do me a very great favour, if you will admit him to your friendship and assist him in anything in which he may need your help, as far as you can do so without inconvenience. That will be both very gratifying to me and hereafter a source of pleasure to yourself: for you will find that he is eminently honest, cultivated, and attentive.
