Sol Invictus translated as the 'unconquered sun' was recognised by the Roman empire as the sun god. Characterised by a crown of radiating beams, the ancient Romans looked to Sol as a powerful deity of warmth, light and strength and thus became the patron of soldiers. At the height of the sun god's popularity coins, jewels, festivities and games were created in his honour.
