Cyprianus Gallus (fl. c. 397–430) was a fifth-century poet who wrote a Late Latin epic versification of the historical books of the Vetus Latina, though only the Heptateuch (Heptateuchos) has survived to the present day.
It is in Latin, and consists of twenty-five chapters : nine on the letters of the alphabet, three on etymology, one on contractions and cryptic writings, and twelve on prosody and versification.
Bede’s remarks in his De arte metrica were repeated and made more strict by Renaissance guides to versification, ultimately leading to Burles’s description of the golden line.
He edited a combined version of John Walker's and Noah Webster's Dictionaries (London, 1864), and Walker's Rhyming Dictionary (London, 1865), with an introduction on English versification.
Patri Fidiel (1762–1824) was a Capuchin, author of poems about religious aspects and with a popular traditional versification.
A definitive example of focus on poetic language is the study of Russian versification by Osip Brik.
