Lerna — Greek Mythology
Lerna is a low, marshy district in the Argos region of Greek mythology, best known as the site of Heracles' second labor, the slaying of the Lernaean Hydra. In the geography of Heracles' exploits, it is a place of monster-haunt, poisoned blood, and dispute over the hero's achievement.
Overview
Lerna lies in the region of Argos and is described in the story as a damp lowland marsh linked with reeds and dark water. Deep within the marsh is a cave where the Lernaean Hydra hides; Heracles and Iolaus fight the monster near its entrance.

Role in Greek Mythology
Lerna has a clear narrative function in the Twelve Labors of Heracles. Eurystheus sends Heracles there to kill the Lernaean Hydra, which occupies a cave in the marsh; the task is one of the most important monster combats among Heracles' early exploits.
In the story, Lerna is not a city or palace, but a region made up of marshland, a cave, roadside mud, and stones. The Hydra's poisonous breath, poisonous blood, and regenerating heads all appear together with this damp lowland setting, but this entry treats those details as part of the scene rather than as an explanation of the landscape's mythic meaning.
Geographic Background
Lerna is set in the Argos region and is commonly presented as wet, low-lying, and gloomy. After arriving, Heracles has Iolaus leave the chariot on higher ground while he approaches the cave and drives out the Hydra with burning arrows.
After the battle, Heracles buries the Hydra's immortal head in the roadside earth and pins it down with a great stone. He then dips his arrows in the Hydra's poisonous blood, making them deadly weapons in later stories. Lerna is therefore not only a battlefield, but also the narrative setting for the origin of Heracles' poisoned arrows.
