What kind of sonnet is Sonnet 24 of Philip Sidney's Astrophel and Stella? Here is the sonnet:
Rich fools there be, whose base and filthy heart
Lies hatching still the goods wherein they flow,
And damning their own selves to Tantal’s smart,
Wealth breeding want, more blest, more wretched grow.
Yet to those fools heaven such wit doth impart,
As what their hands do hold, their heads do know
And knowing, love, and loving, lay apart
As sacred things, far from all danger’s show.
But that rich fool, who by blind fortune’s lot
The richest gem of love and life enjoys,
And can with foul abuse such beauties blot,
Let him, deprived of sweet but unfelt joys,
Exiled for aye from those high treasures which
He knows not, grow in only folly rich!
It seems like an English sonnet by rhyme scheme, but the last two lines seem like a part of a longer stanza and not a couplet. So is it more like a Petrarchan sonnet?
