Note 13 — WINDSOR FOREST.
Reading edition
Milton, Par. Lost, iv. 248:
Groves whose rich trees wept odorous gums and balms.
This fancy was borrowed from the ancients. According to Ovid (Met. x. 500), Myrrha, changed into a tree, weeps myrrh, and the sisters of Phæton (Met. ii. 364), transformed into poplars, shed tears which harden in the sun, and turn into amber.
