This volume presents a trilingual edition of Aristotle's Metaphysics. Each paragraph has an English, Latin and (original) Ancient Greek rendition. Students of Classics or anyone interested in ancient philosophy and languages should find in this trilingual edition an a helpful device to approach Aristotle original Greek. The English translation is David Ross' (1908), and the Latin comes from William of Moerbeke's medieval translation. At the end of the volume readers can find an outline of Ancient Greek grammar in tables and graphic explanations. parenthetically, William of Moerbeke's translation was commissioned by Thomas Aquinas, who wanted a Latin rendition as close as possible to the original Greek. As a result, the Latin version does violence at times to the normal Latin syntax, but is very useful for language learning when read in parallel with Aristotle's original text.
