Rig Veda I, 92, 4-5

 Dawn like a dancer puts on her ornaments; as a cow yields her udder, so she bares her bosom. She creates light for all living beings, flinging wide the gates of darkness, as cows their enclosure.

We have beheld the radiance of her shining. Advancing, she drives away the horror of the night. Like a colored post, anointed at the sacrificial feast, so the Dawn, Heaven's daughter, is adorned with wondrous splendor.
