The painting depicts the story from Ovid's Metamorphoses of the weaving contest between the god Athena and the mortal Arachne. In the original myth, Athena challenges Arachne and loses, but Athena punishes Arachne anyway for insulting the gods by not recognizing the divine source of Athena's artistic skill and for creating a more beautiful work than her own.
In the background of the canvas hangs a partially-visible tapestry of Titian's The Rape of Europa which, according to Ovid's version of the story, was the theme of the tapestry woven by Arachne during the contest with Athena.
