How dare you insult the gods and goddesses like that! You should know better than to challenge your superiors! Since you love weaving so much, I should just turn you into a spider as punishment for your disrespect!
Ever since then, Arachne had to live her life as a spider, deep in her lair with her descendants the spiders, where no one had heard of her ever again.
Curse Athena! Curse the Olympians! I hate them all!
When the weaving contest started, the townsfolk were wondering who might win. Some were rooting for Athena while others think that Arachne would win. In the end, Athena wove a tapestry showing how humans were punished for disrespecting the gods and goddesses, while Arachne wove a tapestry showing how the gods and goddesses were really lazy and foolish.
Athena became enraged and insulted at what Arachne wove, thus wanted to punish Arachne. Since Arachne loved to weave so much, Athena considered transforming Arachne into a spider so that she can weave for the rest of her life.
So, ever since then, Arachne was doomed to live her life as the mother of all spiders. Living in her own lair, she grew to hate the gods, goddesses and even humans since no one tried to defend her, and she passed on those bitter hate onto her many descendants of spiders.
