Sonnet 80 (Spenser)
The six books
Spenser had just published Books I-III of *The Faerie Queene* in 1590. This is his announcement that he's taking a break before writing the second half.
Pleasant mew
A **mew** is a cage for hawks during molting season. He's comparing his love poetry (*Amoretti*) to a resting place between epic flights.
Low and meane
**Mean** here means 'humble' or 'middle-style,' not petty. He's placing his love sonnets in a lower literary register than epic poetry.
Handmayd hierarchy
Elizabeth Boyle (his beloved) is the 'handmaid' to Queen Elizabeth (the Faery Queene). This is both courtly flattery and a ranking of his poetic projects.
