The will or testament of the philosopher is preserved.[41] Its first words constitute Antipater his general executor in the most comprehensive terms,[42] words well calculated to ensure that his directions should be really carried into effect; since not only was Antipater now the supreme potentate, but Nikanor, the chief beneficiary under the will, was in his service and dependent on his orders. Aristotle then proceeds to declare that Nikanor shall become his son-in-law, by marriage with his daughter Pythias as soon as she shall attain suitable age; also, his general heir, subject to certain particular bequests and directions, and the guardian of his infant son Nikomachus. Nikanor being at that time on service, and perhaps in Asia, Aristotle directs that four friends (named Aristomenes, Timarchus, Hipparchus, Diotelês) shall take provisional care of Herpyllis, his two children, and his effects, until Nikanor can appear and act: Theophrastus is to be conjoined with these four if he chooses, and if circumstances permit him.[43] The daughter Pythias, when she attains suitable age, is to become the wife of Nikanor, who will take the best care both of her and her son Nikomachus, being in the joint relation of father and brother to them.[44] If Pythias shall die, either before the marriage or after it, but without leaving offspring, Nikanor shall have discretion to make such arrangements as may be honourable both for himself and for the testator respecting Nikomachus and the estate generally. In case of the death of Nikanor himself, either before the marriage or without offspring, any directions given by him shall be observed; but Theophrastus shall be entitled, if he chooses, to become the husband of Pythias, and if Theophrastus does not choose, then the executors along with Antipater shall determine what they think best both for her and for Nikomachus.[45] The will then proceeds as follows:--"The executors (here Antipater is not called in to co-operate) with Nikanor, in faithful memory of me and of the steady affection of Herpyllis towards me, shall take good care of her in every way, but especially if she desires to be married, in giving her away to one not unworthy of me. They shall assign to her, besides what she has already received, a talent of silver, and three female slaves chosen by herself, out of the property, together with the young girl and the Pyrrhæan slave now attached to her person. If she prefers to reside at Chalkis, she may occupy the lodging near the garden; if at Stageira, she may live at my paternal house. Whichever of the two she may prefer, the executors shall provide it with all such articles of furniture as they deem sufficient for her comfort and dignity."[46]
