Overview
In Greek mythology, Iole was the daughter of King Eurytus of Oechalia. According to the brief epitome in the Bibliotheca, Eurytus had a beautiful young daughter named Iole who was eligible for marriage. Iole was claimed by Heracles for a bride, but Eurytus refused her hand in marriage. Iole was indirectly the cause of Heracles' death because of his wife's jealousy of her.
There are different versions of the mythology of Iole from many ancient sources. The Bibliotheca gives the most complete story followed by slight variations of this from Seneca and Ovid. Other ancient sources (i.e. Diodorus Siculus, Gaius Julius Hyginus, and Pseudo-Plutarch) have similar information on Iole with additional variations.
Mythology
Heracles' love for Iole leads to his death
Apollodorus recounted the tale in his Bibliotheca. King Eurytus was an expert archer who taught his sons his knowledge of the bow and arrow. He promised his daughter Iole to whoever could beat him and his sons in an archery contest. The sons shot so well that they beat all the others from the kingdom. Heracles then heard of the prize and eagerly entered the contest, for he desired the maiden. Heracles shot with keenness and even beat Eurytus' scores. It is ironic because Eurytus, in his early years, had taught Heracles to become an archer.
