What giant boar was captured by Heracles as his fourth labor?

The Erymanthian Boar was the giant boar Heracles captured as his fourth labor.

Eurystheus ordered Heracles to bring the dangerous animal back alive rather than kill it. The boar ravaged the countryside around Mount Erymanthus in Arcadia, and ancient descriptions present it as enormous, wild, and difficult to control. Heracles pursued it through the mountains and drove it into deep snow, where exhaustion made it easier to trap.

After binding the boar, Heracles carried it back to Mycenae. Eurystheus was so frightened that he hid inside a large bronze storage jar or pithos. This comic detail contrasts with the fearsome reputation of the animal and became a familiar scene in artistic depictions of the labors.

The boar is different from the Nemean Lion, which was Heracles’ first labor, and from the Calydonian Boar, hunted by a separate group of heroes. It is also distinct from the Crommyonian Sow, another monstrous pig associated with the hero Theseus. The exact storytelling details vary among ancient authors, but the fourth-labor identification is standard.
