Edited sentence: A principal contribution to scholarship is Powell's Homer and the Origin of the Greek Alphabet (Cambridge University Press, 1991), which advances the thesis that a single man invented the Greek alphabet expressly in order to record the poems of Homer.Books available through Amazon.His Homer (Blackwells, 2003), a concise discussion of the poet and his poems, is a best selling study of Homer.Powell is the Halls-Bascom Professor of Classics Emeritus at the University of Wisconsin-Madison, visiting professor at the University of New Mexico, and author of the widely used textbook Classical Myth (fifth edition, Prentice-Hall, 2006), as well as The Greeks (Prentice-Hall 2005, with Ian Morris) and A Short Introduction to Classical Myth (Prentice-Hall, 2000).Powell's many other books include an illustrated novel Ramses in Nighttown (2005) and an illustrated book of poetry Rooms Containing Falcons (2005) He has also written screenplays, including one on Helen of Troy, and a humorous mock-epic The War at Troy: A True History (2006).This thesis is controversial but appears to make the best sense of complex evidence for the invention of the Greek alphabet and the previously unsolved problem of the creation of the Homeric texts
