English poet, dramatist, and traveller, whose writings are notable for both the praise and the ridicule they evoked.

Flecknoe was possibly a Jesuit of Irish extraction. The most authentic information about him is contained in his Relation of Ten Years' Travels in Europe, Asia, Affrique, and America (1654?). Flecknoe's picture of himself as a ladies' man contrasts sharply with Andrew Marvell's account in his poem “Flecknoe, an English Priest at Rome,” which ridicules Flecknoe's threadbare asceticism and bad verses. Dryden lampooned him in his hostile MacFlecknoe (1682) as being “Through all the realms of Nonsense, absolute.” Neither his poems in Epigrams of all sorts (1670) nor his prose sketches in Enigmatical characters (1658) warrant such an attack. His The Short Treatise of the English Stage, appended to a revision of his play Love's Kingdom (1664), is of considerable historical interest.
