But when he awoke at length there was a great Phoenix brooding with spread wings above his prostrate form, its white plumage like a ghostly crepuscule and its red eyes glowing close against his own pallid and fervent face.

For that is Anayat in the crepuscule, purple and mellow, sparkling and warm and effulgent when there is a moon, cool and heady and sensuous when there is no moon.
