Answer:
Athena taught Arachne that it is not proper to brag about your talents when she challenged her to a weaving contest after Arachne had been bragging about her skill and how she could win against Athena. She also taught her a lesson not to be rude when Arachne created a weaving of the Gods and Goddesses on Mount Olympus drunk, stumbling, and messing things up. Athena was so furious with this that she said "If you want to weave, go ahead and weave!" and turned Arachne into a small spider. Arachne means spider, and that is why we call spiders arachnids today.
