The Iliad 5.352–358

Anon she found furious Ares abiding on the left of the battle, and upon a cloud was his spear leaning, and at hand were his swift horses twain. Then she fell upon her knees and with instant prayer begged for her dear brother's horses with frontlets of gold: Dear brother, save me, and give me thy horses,that I may get me to Olympus, where is the abode of the immortals. For sorely am I pained with a wound which a mortal man dealt me, Tydeus' son, that would now fight even with father Zeus.
