[hypothesis]
Cleonymus having died, his nephews claim his estate as the natural heirs. They admit that the will in favor of Pherenicus, Simon,1 and Poseidippus, and produced by these persons, was the genuine will of Cleonymus, and was deposited by Cleonymus with the magistrates at a time when he was angry with their guardian Deinias; they allege, however, that he subsequently tried to annul the will, and after having sent for the police-magistrate, died suddenly. They further allege that Polyarchus, their grandfather and Cleonymus's father, instructed the latter, if anything should happen to him, to leave his property to them. The question at issue is a decision between the conflicting claims of the two parties, one basing their claim on the original will, the other relying on the last acts of Cleonymus, and alleging that he sent for the magistrate in order to annul the will.
1 The insertion of Simon's name here is a mistake; he was only a friend of Cleonymus (see Isaeus 1.31-32).
