Love's Metamorphosis was entered into the Stationers' Register on 25 November 1600, and was first published in 1601 in a quarto issued by the bookseller William Wood.
The subplot involves the churlish and brutal peasant Erisichthon, who chops down a sacred tree and thereby takes the life of Fidelia, a transformed nymph.
Protea escapes her servitude via a prayer to Neptune and a disguise as a fisherman; she returns home, and masquerades as the revenging ghost of Ulysses to rescue Petulius, her beloved, from a Siren.
The nymphs are restored to their original forms once they agree to accept the three humans as husbands; the quadruple wedding is held at the house of Erisichthon.
Love's Metamorphosis differs from most of Lyly's plays in that it lacks the overtly comical and farcical elements that Lylian dramas normally possess.
