From Metamorphoses 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 The History of the Peloponnesian War. By Thucydides

Beginning with the Odrysians, he first called out the Thracian tribes subject to him between Mounts Haemus and Rhodope and the Euxine and Hellespont; next the Getae beyond Haemus, and the other hordes settled south of the Danube in the neighbourhood of the Euxine, who, like the Getae, border on the Scythians and are armed in the same manner, being all mounted archers. Besides these he summoned many of the hill Thracian independent swordsmen, called Dii and mostly inhabiting Mount Rhodope, some of whom came as mercenaries, others as volunteers; also the Agrianes and Laeaeans, and the rest of the Paeonian tribes in his empire, at the confines of which these lay, extending up to the Laeaean Paeonians and the river Strymon, which flows from Mount Scombrus through the country of the Agrianes and Laeaeans; there the empire of Sitalces ends and the territory of the independent Paeonians begins. Bordering on the Triballi, also independent, were the Treres and Tilataeans, who dwell to the north of Mount Scombrus and extend towards the setting sun as far as the river Oskius. This river rises in the same mountains as the Nestus and Hebrus, a wild and extensive range connected with Rhodope.

From Homeric Hymn to Demeter

[Line 405] Then beautiful Persephone answered her thus: "Mother, I will tell you all without error. When luck-bringing Hermes came, swift messenger from my father the Son of Cronos and the other Sons of Heaven, bidding me come back from Erebus that you might see me with your eyes and so cease from your anger and fearful wrath against the gods, I sprang up at once for joy; but he secretly put in my mouth sweet food, a pomegranate seed, and forced me to taste against my will. Also I will tell how he rapt me away by the deep plan of my father the Son of Cronos and carried me off beneath the depths of the earth, and will relate the whole matter as you ask. All we were playing in a lovely meadow, Leucippe and Phaeno and Electra and Ianthe, Melita also and Iache with Rhodea and Callirhoe and Melobosis and Tyche and Ocyrhoe, fair as a flower, Chryseis, Ianeira, Acaste and Admete and Rhodope and Pluto and charming Calypso; Styx too was there and Urania and lovely Galaxaura with Pallas who rouses battles and Artemis delighting in arrows.[5] We were playing and gathering sweet flowers in our hands, soft crocuses mingled with irises and hyacinths, and rose-blooms and lilies, marvellous to see, and the narcissus which the wide earth caused to grow yellow as a crocus. That I plucked in my joy; but the earth parted beneath, and there the strong lord, the Host of Many, sprang forth and in his golden chariot he bore me away, all unwilling, beneath the earth: then I cried with a shrill cry. All this is true, sore though it grieves me to tell the tale."
