According to mythology, Leros was the island of the goddess of hunting who visited the island regularly to hunt. The remnants of a sanctuary testify the worship to Artemis.
According to mythology, Leros is associated with the town of Calydon in Aetolia. During the reign of Oeneus in Calydon, the goddess Artemis sent a wild boar which laid waste to the fields and terrified the locals. At that time, Meleager, a mythical hero and son of Oeneus and Althaea, succeeded to the throne and then killed this animal.
Nevertheless, Artemis regarded the slaying of the boar as an insult and profane. This is why she took revenge on Meleager by planning his early death. However, the intense grief of Meleager’s sisters over his death brought about the goddess’s sympathy. So Artemis took them to Leros and transformed them into birds, the well-known Meleagrides.
