In Greek mythology, the character who was turned into a spider as punishment for her arrogance is Arachne. A skilled weaver, Arachne boasted that her skill surpassed that of the goddess Athena. Enraged by this hubris, Athena challenged her to a weaving contest. Although Arachne created a beautiful tapestry, she insulted the gods within it, prompting Athena to transform her into a spider, condemning her to weave for eternity. This myth illustrates themes of pride, humility, and the complex relationship between humans and deities in Greek culture, serving as a cautionary tale against arrogance.
