The Eight Principal Vices' is one of the various Latin prose composed by the 7th century Anglo-Saxon saint, Aldhelm. It deals with the subject of morality and cautions against the sundry vices that might pose a threat to a Christian's soul. It is similar in its composition to work by Eutropius, Aldhelm's Visigothic contemporary. This work includes both the original Latin text as well as the English translation.
