KORYMBOS (or Corymbus) was the rustic Daimon (Spirit) of the fruit of the ivy. He was a companion of the god Dionysos, whose mother Mystis nursed on the island of Euboia. The two are presumed to have shared the same cradle (like Melikertes in the alternate Boiotian myth of Ino). Of these figures, Mystis ("of the Mysteries") probably personfied intiation into the Bacchic orgies, while her son Korymbos was the god of the sacred ivy, the plant with which intitiates were crowned.
His name is similar to that of Korybas (Corybas), eponym of the shield-clashing Korybantes, who were the Euboian guardians of the infant Dionysos.
He also might be related to the rustic gods Aristaios and Melisseus, both of whom were also described as armed protectors of the infant god.
|MYSTIS (Nonnus Dionysiaca 13.135)
Nonnus, Dionysiaca 13. 135 ff (trans. Rouse) (Greek epic C5th A.D.) :
"Shield-bearing Korybantes (Corybantes) [of Euboia], guardians of Dionysos in his growing days: who in the Phrygian gulf beside mountain-ranging Rheia surrounded Bakkhos (Bacchus) still a child with their drumskins. They found him once, a horned baby, covered with a cloak the colour of purple wine, lying among the rocks where Ino had left him in charge of Mystis the mother of Korymbos (Corymbus)."
