[XXXII.] Atlas was the giant who held apart heaven and earth. Virgil identifies him with the mountains which lie in North Africa between the sea and the desert of Sahara. Atlas was the father of Maia, the mother of Mercury. The latter is called 'Cyllenius' from his birth-place, Mount Cyllene in Arcadia.
[XXXVIII.] Mount Cithaeron, near Thebes, was famous for the revels which took place there in honour of Bacchus.
[XLIV.] Phoebus (Apollo) is called 'Grynoeus' from Grynium, a city of Aeolis in Asia Minor. He was much worshipped in Lycia, hence his oracles are often called 'Lycian lots.'
[LV.] It was at Aulis in Boeotia that the Greek expedition against Troy mustered.
[LX.] In this passage Virgil has in mind the Bacchae of Euripides, in which Pentheus goes mad, and perhaps the Eumenides of Aeschylus, but it is more probable that in the latter case he is merely thinking of Orestes as he is represented in tragedy.
