Museum Piece by Richard Wilbur

The good gray guardians of art
Patrol the halls on spongy shoes,
Impartially protective, though
Perhaps suspicious of Toulouse.

Here dozes one against the wall,
Disposed upon a funeral chair.
A Degas dancer pirouettes
Upon the parting of his hair.

See how she spins! The grace is there,
But strain as well is plain to see.
Degas loved the two together:
Beauty joined to energy.

Edgar Degas purchased once
A fine El Greco, which he kept
Against the wall beside his bed
To hang his pants on while he slept.

In the art world, different people (even those who claim they are artists) treat art with different attitude. Guardian is suspicious of Toulouse; another dozes upon Degas dancer; Degas despises El Greco. They have different perspectives and interpretations about art and adopt different attitude towards it (i.e. See how Degas hangs his pants on El Greco!)
