Instruct me, for Thou know’st; Thou from the first
Wast present, and with mighty wings outspread
Dove-like satst brooding on the vast Abyss
Hung on his shoulders like the Moon
Can either Sex assume, or both; so soft
And uncompounded is their Essence pure,
Not ti’d or manacl’d with joynt or limb,
Nor founded on the brittle strength of bones,
Like cumbrous flesh; but in what shape they choose
Dilated or condens’t, bright or obscure,
Can execute their aerie purposes,
And works of love or enmity fulfill.
Paradise Lost
