Sol Invictus
From Tardis Wiki, the free Doctor Who reference
The Sol Invictus was a god to the Syrians and Romans. The Syrians worshipped a Vondraxian orb as the Sol Invictus. (PROSE: Trace Memory)
Sometime after 47 BC, the Feast of Sol Invictus was a celebration that supplanted the holiday of Saturnalia in Rome. A theory existed that 25 December was chosen for the date of Christmas because the Feast of Sol Invictus already existed on that date. (PROSE: The Best of Days)
In 219 AD, Emperor Elagabalus entered Rome with the Vondraxian orb. (PROSE: Trace Memory)
