Theopompus of Chios
Theopompus of Chios (c. 4th Cent. BC.) is quoted by Aelian (i) where he seems to describe a continent on the far side of the Atlantic in terms similar to Plato’s account of Atlantis. This excerpt is reputed to be from a play of Thespis, a contemporary of Solon, who is believed to have parodied Solon’s Atlantis poem, which, if true, adds credence to the view that Atlantis was not just an invention of Plato’s.
However, N. Zhirov urges caution as ‘Theopompus was considered a writer of fables even in antiquity’. *Stephen P. Kershaw notes that Aelian “exposes how Theopompus quite flagrantly ripped off the Timaeus and the Critias.” [1585.109]*
Ignatius Donnelly points out that Theopompus referred to Atlanteans as Meropes. In spite of any misgivings about reliability of Theopompus it would appear that he personally accepted the existence of Atlantis.
