"Ovid's a rake, as half his verses show him, Anacreon's morals are a still worse sample, Catullus scarcely has a decent poem, I don't think Sappho's Ode a good example, Although Longinus tells us there is no hymn Where the sublime soars forth on wings more ample; But Virgil's songs are pure, except that horrid one Beginning with "Formosum Pastor Corydon.""
