Hudibras

On the one side some who have had very little human learning, but were endued with a large share of natural wit and parts, have become the most celebrated (Shakespear, D'Avenant, &c.) poets of the age they lived in. But, as these last are, "Rarae aves in terris," so, when the muses have not disdained the assistances of other arts and sciences, we are then blessed with those lasting monuments of wit and learning, which may justly claim a kind of eternity upon earth.
