Origin of the Catoblepas, Another Perspective

When a herder boasted that his cattle were Theros’s finest because Heliod and Nylea had created them, Heliod persuaded Mogis to curse the cattle, transforming them into the first catoblepases. Heliod had hoped to win Nylea’s favor by defending her honor in this way, but she was outraged to be associated with the creation of these abominations. To this day, Nylea offers a boon to anyone who hunts down a catoblepas and brings its head to her sacred grove.
