In Sir Philip Sidney's Defence of Poesie (also known as An Apology for Poetry), he refers to poet-haters as "Mysomousoi." This term comes from Greek, where "mysos" means "hatred" or "disgust" and "mousa" refers to the Muses, the goddesses of the arts and literature. Therefore, "Mysomousoi" means "haters of the Muses" or "haters of poetry."
The other options don't fit this context:
Misogynists – those who hate women.
Misanthropes – those who hate humanity in general.
Misnomers – incorrect or inaccurate names.
Thus, the correct answer is 4: Mysomousoi, which specifically refers to those who despise or hate poetry.
