"Intriguingly linked with this imprecision is the hysteron proteron of line 6, whose uncertain sequence of bearing arms, and then learning their use opens more space between the two acts than it closes." Bruce Danner, Courteous virtu in Spenser's Book 6 of 'The Faerie Queene.' Studies in English Literature, Winter 1998.
