Haemus
1. A son of Boreas and Oreithyia, was married to Rhodope, by whom he became the father of Hebrus. As he and his wife presumed to assume the names of Zeus and Hera, both were metamorphosed into mountains. (Metamorphoses by Ovid)
2. A son of Ares, and an ally of the Trojans in the war with the Greeks. (Tzetzes)
From Smith's Dictionary of Greek and Roman Biography and MythologyMetamorphoses by Ovid. Book The Second
The mountains kindle as the car draws near,
Athos and Tmolus red with fires appear;
Oeagrian Haemus (then a single name)
And virgin Helicon increase the flame;
Taurus and Oete glare amid the sky,
And Ida, spight of all her fountains, dry.
Eryx and Othrys, and Cithaeron, glow,
And Rhodope, no longer cloath'd in snow;
High Pindus, Mimas, and Parnassus, sweat,
And Aetna rages with redoubled heat.
Ev'n Scythia, through her hoary regions warm'd,
In vain with all her native frost was arm'd.
Cover'd with flames the tow'ring Appennine,
And Caucasus, and proud Olympus, shine;
And, where the long-extended Alpes aspire,
Now stands a huge continu'd range of fire.
From Pharsalia aka The Civil War By Lucan
But thou, Caesar, to what gods of ill
Didst thou appeal? What furies didst thou call,
What powers of madness and what Stygian Kings
Whelmed in th' abyss of hell? Didst favour gain
By sacrifice in this thine impious war?
Strange sights were seen; or caused by hands divine
Or due to fearful fancy. Haemus' top
Plunged headlong in the valley, Pindus met
With high Olympus, while at Ossa's feet
Red ran Baebeis, (8) and Pharsalia's field
Gave warlike voices forth in depth of night.
