Protean
An English adjective meaning versatile, adaptable, or constantly changing in form, derived from the sea god Proteus who could transform himself into any shape to avoid capture
The Meaning of Protean
The word "protean" entered English from the myth of Proteus, the Old Man of the Sea who served as a herdsman for Poseidon's seals. Proteus possessed the gift of prophecy but despised giving answers to mortals. To avoid questioning, he could change his shape at will — becoming a lion, a serpent, a torrent of water, a blazing fire, or a tree. Only those who could wrestle him through all his transformations and hold on would earn his prophecy. Menelaus, stranded in Egypt on his return from Troy, was advised by the sea nymph Eidothea to seize Proteus at dawn on the beach of Pharos. Menelaus held fast through every metamorphosis until the god, exhausted, returned to his true form and answered his questions. The adjective "protean" was first used in English in the sixteenth century and now appears across every field of discourse. A protean actor plays many roles convincingly. A protean thinker moves fluidly between disciplines. Protean proteins in biology change their structure depending on conditions. The word captures the Greek philosophical interest in change, identity, and the relationship between form and essence.
