Plato disliked all the arts.
He thought that an artistic representation was a copy of what was in the world, itself a copy of the truth of the perfect object as it would have appeared in platonic heaven. He wanted to banish all artists from the Republic because their creations of the counterfeit. He thought maths was the way to the platonic heaven. (I can't remember, but I think he was pretty bigoted also, St Paul taking a lot of his ideas to explain Christianity and Christian ethics.)
Plato was a miserable sod, if his Republic had existed I would have lived in some disorganised artist's shanty town, not far away.
