"[T]he cool new crop of models at agencies like Major [are] guys closer to the Ivy League Adonis ideal of yesteryear...." Guy Trebay, NYTimes.com, July 21, 2010
About the word:
In Greek mythology, the beautiful young Adonis was beloved by both Persephone and Aphrodite, so Zeus decreed the young man should divide his time and attention between the two goddesses.
He was later killed by a wild boar an attack that may have been arranged to avenge another of Adonis' romantic intrigues.
