Question: How many poems were written by the first English poet to write mock-heroic ottava rima? Passage:In English, ottava rima first appeared in Elizabethan translations of Tasso and Ariosto. The form also became popular for original works, such as Michael Drayton's The Barons' Wars, Thomas Heywood's Troia Britannica, or Aemilia Lanyer's Salve Deus Rex Judaeorum. William Browne's Britannia's Pastorals also contains passages in ottava rima. The first English poet to write mock-heroic ottava rima was John Hookham Frere, whose 1817-8 poem Prospectus and Specimen of an Intended National Work used the form to considerable effect. Lord Byron read Frere's work and saw the potential of the form. He quickly produced Beppo, his first poem to use the form. Shortly after this, Byron began working on his Don Juan (18191824), probably the best-known English poem in ottava rima. Byron also used the form for The Vision of Judgment (1822). Shelley translated the Homeric Hymns into English in ottava rima. In the 20th century, William Butler Yeats used the form in several of his best later poems, including "Sailing to Byzantium" and "Among School Children". So did Kenneth Koch for instance in his autobiographical poem "Seasons on Earth" of 1987. In America Emma Lazarus wrote the poem An Epistle that consists of thirty four ottava rimas. Earlier Richard Henry Wilde used the stanza in his long poem Hesperia.
