The epigraph of James Joyce's Portrait Of The Artist As A Young Man.

Originally from a description of Daedalus in the Metamorphoses of Ovid (P. Ovidius Naso), VIII:188.

Translation: "And he sets his mind to unknown arts" (in Metamorphoses the line continues, "and changes the laws of nature").

The full line, in Latin, is: ignotas animum dimittit in artes naturamque nouat.
