Collings is best known, however, as a caricaturist; he was a friend of Thomas Rowlandson, and contributed designs, which were etched by Rowlandson for some of his satirical publications, notably the satires on Johnson and Boswell's "Tour to the Hebrides", (published by Elizabeth Jackson in 1786), and on Goethe's "The Sorrows of Young Werther".
