Julia Domna Empress of the Roman Empire from 193 to 217.
Iulia Domna was Empress consort of the Roman Empire, being wife to the Roman Emperor Lucius Septimius Severus and mother of Emperors Geta and Caracalla.

Julia was famous for her prodigious learning as well as her extraordinary political influence, and is remembered for being a patron of the arts, music, and philosophy, using her title and influence to spread the previously persecuted Philosophy and helping it improve and flourish in Rome. She was respected and viewed positively for most of her tenure

When her remaining son Caracalla was assassinated and succeeded (briefly) by Macrinus, Julia chose to commit suicide after hearing about the rebellion. A decision perhaps hastened by the fact that she was suffering from breast cancer.

Julia Domna, wife of Emperor Septimius Severus, was associated with Luna Lucifera, "the light-bearing Moon", while Severus associated himself with Sol, god of the Sun. The concept of identifying themselves with Sun and Moon speaks of the eternal nature of the imperial house. On the reverse of this wonderful coin, struck during the reign of her son Caracalla, we see Luna driving a two-horse chariot (a “biga”), whilst her cloak bellows in the wind around her.
