John Myles Dillon (; born 15 September 1939) is an Irish classicist and philosopher who was Regius Professor of Greek in Trinity College, Dublin between 1980 and 2006. Prior to that he taught at the University of California, Berkeley. He was elected a corresponding member of the Academy of Athens on 15 June 2010, and in July 2022 a corresponding member of the British Academy. Dillon's area of research lies in the history of Platonism from the Old Academy to the Renaissance, and also Early Christianity.
Among Dillon's most famous works are his translations of Iamblichus' On the Mysteries of the Egyptians, a definitive book on Middle Platonists and Neoplatonism, and his editorial work on Stephen McKenna's translation of Plotinus' Enneads. With the latter, he continued the same research as his predecessor A. H. Armstrong in the field of Neoplatonic philosophy.
Dillon is also a member of the International Society for Neoplatonic Studies,[1] and is in addition a member of the Editorial Advisory Council of Dionysius.[2] [3] His first novel, The Scent of Eucalyptus, was published in 2007 by the University Press of the South.[4] and in 2020, a fully revised second edition of the novel was published by 451 Editions, Dublin.[5]
