As soon as Demosthenes came of age in 366 BC, he demanded his guardians render an account of their management. According to Demosthenes, the account revealed the misappropriation of his property. Although his father left an estate of nearly fourteen talents (equivalent to about 220 years of a labourer's income at standard wages, or 11 million dollars in terms of median U.S. annual incomes).* D. M. MacDowell, "Demosthenes the Orator", ch. 3.</ref> Demosthenes asserted his guardians had left nothing "except the house, and fourteen slaves and thirty silver " (30 = ½ talent). At the age of 20 Demosthenes sued his trustees to recover his patrimony and delivered five orations: three "Against Aphobus" during 363 and 362 BC and two "Against Onetor" during 362 and 361 BC. The courts fixed Demosthenes' damages at ten talents.* D. M. MacDowell, "Demosthenes the Orator", ch. 3.</ref> When all the trials came to an end, he only succeeded in retrieving a portion of his inheritance.
