Diogenes Laertius Vitae philosophorum 9.7.39

[39] The same authority states that, when he returned from his travels, he was reduced to a humble mode of life because he had exhausted his means; and, because of his poverty, he was supported by his brother Damasus. But his reputation rose owing to his having foretold certain future events; and after that the public deemed him worthy of the honour paid to a god. ¹ There was a law, says Antisthenes, that no one who had squandered his patrimony should be buried in his native city. Democritus, understanding this, and fearing lest he should be at the mercy of any envious or unscrupulous prosecutors, read aloud to the people his treatise, the Great Diacosmos, the best of all his works; and then he was rewarded with 500 talents; and, more than that, with bronze statues as well; and when he died, he received a public funeral after a lifetime of more than a century.
