Epitome margaritae eloquentiae

The Epitome margaritae eloquentiae in Leeds Special Collections is the only surviving copy of a book on rhetoric written in Latin by Lorenzo Guglielmo Traversagni (c.1425-1503). The author used the pen name Guillermus Saphoensis in this work.
Traversagni was a Franciscan friar and humanist scholar from Savona, Northern Italy. Considered to have been the first humanist professor of rhetoric at the University of Cambridge, Traversagni wrote the "Margaritae eloquentiae" as a guide to rhetoric and the art of preaching. The original book was published in 1478 under the full title of "Rhetorica nova, sive, Margarita eloquentiae castigate ad eloquendum divina accommodata," ("The new rhetoric, or, The pearl of purified eloquence, adapted to the expression of matters divine").
The "Epitome margaritae eloquentiae" is a short summary of "Rhetorica nova" and was finished during Traversagni's stay in Paris in 1480. It was only ever published in England by William Caxton probably in the same year. Traversagni is known to have visited England twice in the 1470s and may have paid Caxton to print the book. Traversagni could then sell copies to his pupils. In the "Epitome" Traversagni argues that preaching is a rhetorical skill which aims to promote Christian virtue. At Cambridge Traversagni had lectured on Aristotle's "Ethics" and also the "Rhetorica ad Herennium" attributed to Cicero. He uses these philosophers' concepts of demonstrative logic to prove his point.
