Delia Cruscans, a set of English sentimental poetasters, the leaders of them hailing from Florence, that appeared in England towards the close of the 18th century, and that for a time imposed on many by their extravagant panegyrics of one another, the founder of the set being one Robert Merry, who signed himself Della Crusca; he first announced himself by a sonnet to Love, in praise of which Anne Matilda wrote an incomparable piece of nonsense; “this epidemic spread for a term from fool to fool,” but was soon exposed and laughed out of existence.
