The words of this famous epigram on the Greek monument at the site of the Battle of Thermopylae, written by Simonides of Ceos, have sometimes been presented as if they were literally words of Leonidas; some translations follow
Ō xein', angellein Lakedaimoniois hoti tēide
keimetha tois keinōn rhēmasi peithomenoi.
keimetha tois keinōn rhēmasi peithomenoi.
