Franz Cumont,
The Oriental Religions in Roman Paganism
“ Seeing the creeks descend in noisy foaming cascades, or hearing the roaring of steers in the uplands and the strange sounds of the wind-beaten forests, the Thracians thought they heard the voice and the calls of the lord of that empire, and imagined a god who was fond of extravagant leaps and of wild roaming over the wooded mountains. This conception inspired their religion, for the surest way for mortals to ingratiate themselves with a divinity was to imitate him, and as far as possible to make their lives resemble his. ”
