This chapter champions the erotic sonnets of the Caelica cycle, often ignored in favour of the philosophical and religious poems of the middle, and final section of the sequence; highlighting both their playful eroticism and philosophical depth. The love poetry which scrutinizes the relationship between the mistress and the lover in terms of projection and fetishization, on closer inspection turns out to share the same philosophical grounds as the poems which examine the mechanisms of spiritual slavery later in the cycle. While certain poems, such as Caelica 39, 43, and 56 explicate the link between courtly love and idolatry, this chapter argues how Greville’s poetry contributes to the debates on the status of the imagination in Renaissance poetics, faculty psychology, and religious controversy, by exploring its affective investment in the act of poetic fiction-making.
