ECQUO, EKKO. When Juno discovered that Echo's incessant chatter was a ruse to detain her while Jupiter flirted, she deprived the nymph of her speech but did allow her to echo the last phrase of conversations. Afflicted thus, Echo met Narcissus and fell in love with him; he would not return her love, and she wasted away until only her voice remained (Met III.339-510).
The Clerk alludes to the incessant chatter, ClT 1189. Ekko died because she could not tell her woe, FranklT 951, and because Narcissus would not love her, BD 735-736. [Narcisus]
Ecquo, the OF variant, appears in medial position, BD 735; Ekko, the ME variant, appears in medial position, ClT 1189, and in final rhyming position, FranklT 951.
