The Epistles (Greek: Ἐπιστολαί; Latin: Epistolae) of Plato are a series of thirteen letters traditionally included in the Platonic corpus. With the exception of the Seventh Letter, they are generally considered to be forgeries, although many scholars even reject the seventh.They were "generally accepted as genuine until modern times"; but by the close of the nineteenth century, many philologists believed that none of the letters were actually written by Plato. The Epistles focus mostly on Plato's time in Syracuse and his influence on the political figures Dion and Dionysius. They are generally biographical rather than philosophical, although several, notably the Seventh Letter, gesture at the doctrines of Plato's philosophy. Only two, the Second and Seventh, directly reference Plato's teacher Socrates, the major figure within his philosophical dialogues. Authenticity The two letters that are most commonly claimed to have actually been written by Plato are the Seventh and the Eighth, on the supposition that these were open letters and therefore less likely to be the result of invention or forgery. This is not so much because of a presumption in favor of an open letter's authenticity as because of a presumption against that of a private letter: the preservation of the former is unsurprising, while the preservation, dissemination, and eventual publication of the latter requires some sort of explanation. Nevertheless, even the Seventh Letter has recently been argued to be spurious by prominent scholars, such as Malcolm Schofield, Myles Burnyeat, and Julia Annas. George Boas argues that all of the Epistles, including the Seventh, are spurious, a conclusion accepted also, and more recently, by Terence Irwin. Structure of the Epistles The numbering of each letter is due solely to their placement in traditional manuscripts, and does not appear to follow any discernible principle. The addressees of the Epistles fall into three main categories. Four are addressed to Dionysius II of Syracuse (i, ii, iii, xiii), four to Dionysius' uncle Dion and his associates (iv, vii, viii, x), and five to various others (the Fifth to Perdiccas III of Macedon; the Sixth to Hermias of Atarneus, Erastus, and Coriscus; the Tenth to Aristodorus; the Eleventh to Laodamas; and the Ninth and Twelfth to Archytas). First Letter The First Letter is addressed to Dionysius II of Syracuse, and is almost certainly a forgery. In it, Plato supposedly complains of his rude dismissal by Dionysius and predicts an evil end for him. It is
