He inadvertently saw Athena naked, so she struck him blind to ensure he would never again see what man was not intended to see. Chariclo intervened on her son's behalf and begged Athena to have mercy. Athena replied that she could not restore Tiresias's eyesight, so, instead, she gave him the ability to understand the language of the birds and thus foretell the future. Myrmex was a clever and chaste Attic girl who became quickly a favourite of Athena. However when Athena invented the plough, Myrmex went to the Atticans and told them that it was in fact her own invention. Hurt by the girl's betrayal, Athena transformed her into the small insect bearing her name, the ant.

Finally, losing her temper, Athena destroyed Arachne's tapestry and loom, striking it with her shuttle. Athena then struck Arachne across the face with her staff four times. Arachne hanged herself in despair, but Athena
