Milton alludes to the story of Echo and Narcissus in the Lady’s song in “Comus.” She is seeking her brothers in the forest, and sings to attract their attention:

“Sweet Echo, sweetest nymph, that liv’st unseen Within thy aëry shell By slow Meander’s margent green, And in the violet-embroidered vale, Where the love-lorn nightingale Nightly to thee her sad song mourneth well; Canst thou not tell me of a gentle pair That likest thy Narcissus are? O, if thou have Hid them in some flowery cave, Tell me but where, Sweet queen of parly, daughter of the sphere, So may’st thou be translated to the skies, And give resounding grace to all heaven’s harmonies.”

Milton has imitated the story of Narcissus in the account which he makes Eve give of the first sight of herself reflected in the fountain:

Bulfinch's Mythology — Part 81

“That day I oft remember when from sleep I first awaked, and found myself reposed Under a shade on flowers, much wondering where And what I was, whence thither brought, and how. Not distant far from thence a murmuring sound Of waters issued from a cave, and spread Into a liquid plain, then stood unmoved Pure as the expanse of heaven; I thither went With unexperienced thought, and laid me down On the green bank, to look into the clear Smooth lake that to me seemed another sky. As I bent down to look, just opposite A shape within the watery gleam appeared, Bending to look on me. I started back; It started back; but pleased I soon returned, Pleased it returned as soon with answering looks Of sympathy and love. There had I fixed Mine eyes till now, and pined with vain desire, Had not a voice thus warned me: ‘What thou seest, What there thou seest, fair creature, is thyself;’” etc. —_Paradise Lost_, Book IV.

Bulfinch's Mythology — Part 81

No one of the fables of antiquity has been oftener alluded to by the poets than that of Narcissus. Here are two epigrams which treat it in different ways. The first is by Goldsmith:

“ON A BEAUTIFUL YOUTH, STRUCK BLIND BY LIGHTNING “Sure ’twas by Providence designed, Rather in pity than in hate, That he should be like Cupid blind, To save him from Narcissus’ fate.”

“ON AN UGLY FELLOW “Beware, my friend, of crystal brook Or fountain, lest that hideous hook, Thy nose, thou chance to see; Narcissus’ fate would then be thine, And self-detested thou would’st pine, As self-enamoured he.”
