The Roman History · Amm. 18.6.14

Accordingly we adopted the following plan: we lit a lamp and fastened it tightly on a horse, which we turned loose without a rider, and let go where it pleased to our left, while we marched towards the high ground on our right, in order that the Persians might fancy the light a torch held before the general as he proceeded slowly forwards, and so keep on in that direction. And unless we had adopted this precaution we should have been circumvented, and have fallen as prisoners into the power of the enemy.
