Diogenes constructed a rectangular stoa surrounded by a portico, and furnished with statues. and extended about 80 meters. It was originally about 25 000 words long and filled about 260 square metres of wall space. It was discovered in 1884, and the first 64 fragments were published in 1892. Since then, more fragments have been discovered, notably in a series of excavations led by
Martin Ferguson Smith. among the parts discovered in 2008 was a statement on
Plato's theory of cosmogony. The inscription contains three treatises written by Diogenes as well as various letters and maxims: •
A Treatise on Ethics, which describes how
pleasure is the end of life; how
virtue is a means to achieve it; and explains how to achieve the happy life. •
A Treatise on Physics, which has many parallels with
Lucretius, and includes discussions on
dreams, the
gods, and contains an account of the origin of humans and the invention of clothing, speech and writing. •
A Treatise on Old Age, which appears to have defended
old age against the jibes of the young, although little of this treatise survives. •
Letters of Epicurus, which includes a letter to Epicurus' mother on the subject of dreams. ==Notes==
