En el mito de Aracne hay un acto, que se desarrolla con cinco escenas.

Explanation:

En el mito de Aracne hay un solo acto, que se desarrolla con cinco escenas. En este mito, la joven Aracne es muy hábil tejiendo, tanto así se enorgullece de su talento que se compara y se considera mejor que la diosa Atenea. Esto último ofende a la divinidad, que le advierte sobre su egocentrismo, lo que lleva a que ambas mujeres participen en una competencia. Aracne demuestra ser muy hábil pero irrespetuosa, lo que hace enfadar a la diosa. Al final, la joven se da cuenta de su error y se ahorca, pero Atenea se apiada de ella y la transforma en una araña.
