He instructed Archebiades and Phrasias to point him out and introduce him to my father, when he should return from his journey. It is the custom of all bankers, when a private person deposits money and directs that it be paid to a given person, to write down first the name of the person making the deposit and the amount deposited, and then to write on the margin to be paid to so-and-so; and if they know the face of the person to whom payment is to be made, they do merely this, write down whom they are to pay; but, if they do not know it, it is their custom to write on the margin the name also of him who is to introduce and point out the person who is to receive the money. For a grievous misfortune befell this Lycon.
No sooner had he set out, and was sailing around the Argolic gulf, than his ship was captured by pirate vessels and his goods taken to Argos, while he himself was shot down by an arrow, and met his death. Immediately after this mischance this man Callippus came to the bank, and asked whether they knew Lycon, the Heracleote. Phormion, who is here present, answered that they knew him. Was he a customer of yours? He was, said Phormion, but why do you ask? Why? said he, I will tell you. He is dead, and, as it happens, I am proxenos[*](The proxenos was sort of consular agent, empowered to act in the interest of his country and his countryman in a foreign state.) of the Heracleotes. I demand therefore that you show me your books, that I may know whether he has left any money; for I must of necessity look after the affairs of all the men of Heraclea.
On hearing this, men of the jury, Phormion immediately showed him the books, and, when he had done so, and Callippus (it was he himself, and not another) had read them, and had seen in them the entry, Lycon, the Heracleote, sixteen hundred and forty drachmae, to be paid to Cephisiades; Archebiades of Lamptrae will identify Cephisiades, he went off in silence and for more than five months made no mention of the matter.
