The First Labor
Slaying of the Nemean Lion - Constellation Leo
For his first labor Eurystheus commanded that Hercules slay and return with the skin of the Nemean lion, a creature with an impenetrable hide Hera had sent to Nemea to endanger Hercules.
Hercules traveled to the area and scoped out the lay of the land to prepare himself for the struggle. One evening he came across the lion after it had killed and was having dinner. He slyly shot it with arrows from ambush. Even though his arrows were gifts from Apollo, they bounced off the lions hide with no effect.
The lion attacked and the charge and was fended off by Hercules with his club and bare hands. He managed to choke and batter the lion onto death
Hercules skinned the lion using its own claws, the only tool he found that sufficed to cut through the pelt. Afterwards he cured the skin and wore it always like armor.
Zeus in pride of his mighty son and in remembrance to a worthy beast, had the lion immortalized in the heavens as the constellation of Leo.
Hercules returns to Eurystheus with his prize.
