As the goddess of the air, she physically represents both its beneficent calm, and necessary tempest other storm deities (as Chrysaor and Aeolus) being invested with a subordinate and more or less malignant function, which is exclusively their own, and is related to that of Athena as the power of Mars is related to hers in war. So also Virgil makes her able to wield the lightning herself, while Juno cannot, but must pray for the intervention of Aeolus. She has precisely the correspondent moral authority over calmness of mind, and just anger. She soothes Achilles, as she incites Tydides; her physical power over the air being always hinted correlatively. She grasps Achilles by his hair--as the wind would lift it--softly, "It fanned his cheek, it raised his hair, Like a meadow gale in spring" She does not merely turn the lance of Mars from Diomed; but seizes it in both her hands, and casts it aside, with a sense of making it vain, like chaff in the wind;--to the shout of Achilles, she adds her own voice of storm in heaven--but in all cases the moral power is still the principal one--most beautifully in that seizing of Achilles by the hair, which was the talisman of his life (because he had vowed it to the Sperchius if he returned in safety), and which, in giving at Patroclus' tomb, he, knowingly, yields up the hope of return to his country, and signifies that he will die with his friend. Achilles and Tydides are, above all other heroes, aided by her in war, because their prevailing characters are the desire of justice, united in both, with deep affections; and, in Achilles, with a passionate tenderness, which is the real root of his passionate anger Ulysses is her favorite chiefly in her office as the goddess of conduct and design.
