In The Countesse of Pembroke's Arcadia by Sir Philip Sidnei [Sidney], but not knowing what sections you need help with, some classical allusions are found in the beginning portions. The Dedication speaks of the Muses, Delphos and the Oracle. Chapter 1 of Book I speaks of Cupid. Chapter 3 is a jack-pot with several allusions all in one vicinity. The allusions are to Diana, foolish Nymphes, Atlanta, Aeneas, Venus, Helena, Iole, Omphale, Goddesses, and the Muses again, Delphos again, Saturn, Pan, Juno, Cupid again, Iris, Vulcan, Momus.

Thank you so much. I had to drop my interest in this due to ill health, but am now back in the frame, and will look at what you have said.
