This gentleman is the grandson of the celebrated Cecrops of Pennsylvania. He published, in 1796, the Battle of Edington, a tragedy, the argument of which is taken from the History of Alfred. It was acted, privately, for a night or two at the Haymarket, and to the second edition of it were added, Letters on the Drama. The Monthly Reviewers having criticised this tragedy with freedom, Mr. Penn published a Reply to their Strictures, which, we think, he would have done more wisely to have let alone. He has also written a Translation of Signior Ranieri Calsaligi's Letter to Count Alfieri on Tragedy, with notes; and an octavo volume of Poetical Translations and Miscellanies, containing many Odes and Sonnets from Petrarch.
