Now these bodies have a uniform rule, that when a man introduces his own son or an adopted son, he must swear with his hand upon the victims that the child whom he is introducing, whether his own or an adopted son, is the offspring of an Athenian mother and born in wedlock; and, even after the introducer has done this, the other members still have to pass a vote, and, if their vote is favorable, they then, and not till then, inscribe him on the official register; such is the exactitude with which their formalities are carried out.
Such being the rule, the members of the families and of the ward having full confidence in Apollodorus and being well aware that I was his sister's son, passed an unanimous vote and inscribed my name in the public register, after Apollodorus had sworn with his hand upon the victims. Thus I was adopted by him in his lifetime and my name inscribed in the public register as Thrasyllus the son of Apollodorus, after he had adopted me in this manner, as the laws have given him the power to do. To prove that I am speaking the truth, please take the depositions.
