Arachne was an arrogant girl and a weaver in the Greek town of Colophon in Lydia. She dared to challenge the goddess Athena to a contest in weaving. Athena presented the gods seated on high thrones, while Arachne presented them disguised as animals chasing around mortal girls. This made Athena furious, so she beat Arachne with her shuttle. Arachne hung herself in despair, and Athena transformed her into a spider.Arachne -> Arachnid
