Plato's will left two farms and three minae to a boy, the Academy went to his nephew, and the nephew was carried to class paralysed until he took his own life

Plato died in 347 BC and was buried in the Academy. Diogenes Laertius preserves his will. He left an estate at Iphistiadae, which "may not be sold or alienated," to the boy Adeimantus, and a second estate at Eiresidae. He listed three minae of silver, a silver vessel, a cup, a gold ring and an earring, freed a woman named Artemis, and named four household slaves. He said he owed no one anything. His nephew Speusippus, son of his sister Potone, was one of seven executors. Speusippus took over the Academy, not Aristotle, and held it for eight years. The Stanford Encyclopedia says Aristotle and Xenocrates may have left Athens together after Plato's death. Diogenes Laertius says Speusippus was quick to anger. When he was crippled by paralysis, he was carried to the Academy, and Diogenes the Cynic refused to return his greeting, saying a man who could endure to live like that did not deserve one. Speusippus sent for Xenocrates to take over, and in old age, despondent, took his own life. Aristotle bought his books for three talents. A papyrus from Herculaneum says the younger members voted for the first time and chose Xenocrates over two rivals by a narrow margin.
