The date of the "Battle of the Eclipse" has long been calculated as the afternoon of May 25, 585 BC. Modern computer programmes confirm this date for a view point from central Turkey. There has been much scepticism expressed about Thales ability to have predicted the eclipse "in the year in which it did in fact take place", (e.g. Neugebauer). Whether or not Thales was able to do better than make a lucky guess is not of immediate concern to the arguments used here. For our purpose, dating the foundation of Pteria, it is sufficient that:
That Thales, in all probability, would not have been able to make accurate calculations that would have enabled him to predict an eclipse does not by itself necessitate rejection of the account of the battle.
