Day of Sekhmet and the Purifying Flame (Egyptian)
Sekhmet, daughter of Ra, her body spreading a fiery glow, represented the destructive power of the sun and was crowned with a disk and coiled cobra.

(Old) First Day of Ophiuchus
The sun enters the House of Ophiuchus, the lost sign of the zodiac; five days between Scorpio and Sagitarius known to the Greeks as Aesculepius, God of Medicine, grasping the adjacent constellation Serpens, the snake coiled about his body. Ophiuchus, the thirteenth sign, was abolished by St Augustine of Hippo in 600 for being un-Christian. An ancient Babylonian constellation, Nutsirda, (Prince of the Serpent, or Lord of the Underworld) may be identified with Ophiucus,
