Collier's New Encyclopedia (1921)
son of Myrrha, daughter of Cinyras, King of Cyprus, was born in Arabia. Before the birth of her son she was transformed into the tree which produces the fragrant gum, called by her name; this, however, did not hinder his being brought into the world in due season; he grew up a model of manly beauty, and was passionately beloved by Aphrodite (Venus), who quitted Olympus to dwell with him. Hunting was his favorite pursuit, until, having gone to the chase against the entreaties of his mistress, he was mortally wounded in the thigh by a wild boar. Venus, coming too late to his rescue, changed his blood into flowers. After de death, he was said to stand as high in the favor of Persephone (Proserpine) as before in that of Aphrodite; but, the latter being inconsolable, her rival generously consented that Adonis should spend half the year with his celestial, half with his infernal, mistress.
Aiton's Encyclopedia (1910)
a-do'nis, in Greek mythology, a beautiful boy beloved by Venus (Aphrodite). He was slain by a wild boar. Venus sprinkled nectar upon his blood, and therefrom sprang the anemone, or wind flower. At the request of Venus, Zeus decreed that Adonis should spend half the year in the upper and half in the lower world. His death was celebrated by an autumnal, his resurrection by a spring, festival. Adonis is an oriental deity of nature, a type of the decay of nature in autumn and its revival in spring. "Beautiful as Adonis," is a common expression. See Anemone

Son of Cinyras and Myrrha, was a favorite of Venus . He was killed while hunting a wild boar, and, according to Ovid, his blood produced the anemone. Venus was inconsolable at his loss, and at last obtained from Proserpina that Adonis should spend six months on earth with her and six months among the shades. His death and return to the earth were celebrated in annual festivals (Adonia) at Alexandria, Athens , and other places. 2026 Editor's Note: The Adonia festival, celebrated by women, involved planting 'gardens of Adonis '—small pots of fast-growing plants set on rooftops that quickly withered. Women would then mourn Adonis's death by tearing their clothes and beating their breasts in public display of grief. (Ed: BR 2026-06-06)
