Why were both Ode on a Grecian Urn and On the medusa of leonardo Da Vinci in the Florentine Gallery met with criticism once they were written

A: People thought there should be no connection between writing and art.

Explanation:

Poems written about other artistic works such as paintings and songs were known as ekphrasis. This means the literal representation of the medium of sight through words, where paintings or other art forms were given a "voice" describing themselves.

Examples of such works of ekphrasis are Ode on a Grecian Urn and Medusa of Leonardo Da Vinci in the Florentine Gallery. These two poems deal with an art painting form that is given a descriptive aspect through the imagination and words of the poets’ John Keats and P. B. Shelley. But when such works were produced, there was a lot of criticism from even their regular readers who believe that these 'descriptive' works ruin the artistic nature of the paintings they describe. There can be no perfect representation of the visual art form, which the poets seem to try to do. And they believe that art should remain art and be not given any other dimension. They do not need to be replicated in words and are to be left alone, to be enjoyed how they are meant to be.
