By Manuel Gonzáles Prada:

My translation

He who translates badly
Plays the role of lackey
Robed in clothes grotesquely
Mocking the poet with "love."

Spanish original

Mal traductor de poeta
Hace papel de lacayo
Grotescamente vestido
Con los arreos del amo.

Literal translation

Bad translator of poet
Makes role of lackey
Grotesquely dressed
With the trappings of love.
