"The Quest of Gilgamesh", a 1953 radio play by Douglas Geoffrey Bridson, helped popularize the epic in Britain. In the United States, Charles Olson praised the epic in his poems and essays and Gregory Corso believed that it contained ancient virtues capable of curing what he viewed as modern moral degeneracy. The 1966 postfigurative novel "Gilgamesch" by Guido Bachmann became a classic of German "queer literature" and set a decades-long international literary trend of portraying Gilgamesh and Enkidu as homosexual lovers. This trend proved so popular that the "Epic of Gilgamesh" itself is included in "The Columbia Anthology of Gay Literature" (1998) as a major early work of that genre. In the 1970s and 1980s, feminist literary critics analyzed the "Epic of Gilgamesh" as showing evidence for a transition from the original matriarchy of all humanity to modern patriarchy. As the Green Movement expanded in Europe, Gilgamesh's story began to be seen through an environmentalist lens, with Enkidu's death symbolizing man's separation from nature.
