Eurytus or Eurýtos (Ancient Greek: Εύρυτος) was the name of a Spartan warrior, one of the Three Hundred sent to face the Persians at the Battle of Thermopylae in 480 BC.
Eurytus and a companion, Aristodemus were stricken with an eye disease and ordered by Leonidas to return home prior to the final day of the battle.
[1] While lying ill in a nearby village, the two were informed of the Persian encirclement of the pass, and could not reach an agreement on a course of action.
Eurytus donned his armor and turned back, ordering his helot attendant to lead him back to the battle.
Aristodemus returned to Sparta, where he was treated as a disgrace until he redeemed himself when he died fighting at the battle of Plataea the following year.
