Once again we turn to Ancient Greece to delve into one of the world’s most infamous arachnids: the boastful weaver-turned-spider Arachne! Though her story differs here and there depending on the exact source, pretty much all of them tell of Arachne boasting of her weaving skills.
Her lack of humility was so great and so encompassing that Athena took notice and, disguised as an old woman, challenged Arachne to a weave-off. To Athena’s dismay and frustration, the woman did a much finer job during the contest and even weaved a depiction of how divine beings have mistreated humans over the years. Athena was not amused by this insult and beat the weaver, transforming the poor Arachne into an eight-legged insect.
