This late flowering of illumination—coming after Gutenberg's first printed Bible in 1455 or so—has often been seen as a last gasp of medievalism; Johan Huizinga, a great Dutch scholar, writing a seminal book “The Waning of the Middle Ages” just after the first world war, dismissed the period as effete.

additional note: the alternative definition of "effeminate," while tangentially associable with the "decadent" meaning, has apparently come about solely through misunderstanding and subsequent misuse of the word. the meaning has become further corrupted by the frequent and mistaken use of "effete" to mean "elitist," primarily by Republicans describing Democrats in the recent political campaign.
