The biggest change in subject matter was politics, sometimes explicitly and at others hidden deep in allegory and allusion, especially in the 1680s. This accounted for the largest number of catches circulated anonymously in MS (to avoid arrest) though some were openly party propaganda. New habits were also covered; smoking (Aldrich) and congested water travel (Isaak), though conviviality (wine, women and song) accounted for an even greater share than before. Purcell was probably the most prolific contributor with 53 catches to his name including two that are bawdy and many more wrongly attributed to him, most of which are bawdy.
