Moreover, the Greeks are wont to consecrate the ivyDiodorus, i. 17. 4. to Dionysus, and it is said that among the Egyptians the name for ivy is chenosiris, the meaning of the name being, as they say, the plant of Osiris. Now, Ariston,Müller, iii. p. 324. the author of , happened upon a letter of Alexarchus, in which it is recorded that Dionysus was the son of Zeus and Isis, and is called not Osiris, but Arsaphes, spelled with an a, the name denoting virility. Hermaeus,Ibid. iv. p. 427. too, makes this statement in the first volume of his book ; for he says that Osiris, properly interpreted, means sturdy. I leave out of account Mnaseas’sIbid. iii. p. 155. annexation of Dionysus, Osiris, andSerapis to Epaphus, as well as Anticleides’Cf. Jacoby, 140, no. 13. statement that Isis was the daughter of PrometheusCf. 352 a, supra. and was wedded to Dionysus.Cf. Herodotus, ii. 156. The fact is that the peculiarities already mentioned regarding the festival and sacrifices carry a conviction more manifest than any testimony of authorities.
