The relation of the winter solstice to Jesus is also significant. The birth of Mithras was celebrated in the winter solstice with great rejoicings, and Horus was also then born: "His birth is one of the greatest mysteries of the [Egyptian] religion. Pictures representing it appeared on the walls of temples.... He was the child of Deity. At Christmas time, or that answering to our festival, his image was brought out of the sanctuary with peculiar ceremonies, as the image of the infant Bambino is still brought out and exhibited at Rome."[180]
On the fixing of the 25th December as the birthday of Jesus, Williamson has the following: "All Christians know that the 25th December is _now_ the recognised festival of the birth of Jesus, but few are aware that this has not always been so. There have been, it is said, one hundred and thirty-six different dates fixed on by different Christian sects. Lightfoot gives it as 15th September, others as in February or August. Epiphanius mentions two sects, one celebrating it in June, the other in July. The matter was finally settled by Pope Julius I., in 337 A.D., and S. Chrysostom, writing in 390, says: 'On this day [_i.e._ 25th December] also the birth of Christ was lately fixed at Rome, in order that while the heathen were busy with their ceremonies [the Brumalia, in honour of Bacchus] the Christians might perform their rites undisturbed.' Gibbon in his _Decline and Fall of the Roman Empire_, writes: 'The [Christian] Romans, as ignorant as their brethren of the real date of his [Christ's birth] fixed the solemn festival to the 25th December, the Brumalia or winter solstice, when the Pagans annually celebrated the birth of the Sun.' King, in his _Gnostics and their Remains_, also says: 'The ancient festival held on the 25th December in honour of the birthday of the Invincible One,[181] and celebrated by the great games at the Circus, was afterwards transferred to the commemoration of the birth of Christ, the precise date of which many of the Fathers confess was then unknown;' while at the present day Canon Farrar writes that 'all attempts to discover the month and day of the nativity are useless. No data whatever exist to enable us to determine them with even approximate accuracy.' From the foregoing it is apparent that the great festival of the winter solstice has been celebrated during past ages, and in widely separated lands, in honour of the birth of a God, who is almost invariably alluded to as a 'Saviour,' and whose mother is referred to as a pure virgin. The striking resemblances, too, which have been instanced not only in the birth but in the life of so many of these Saviour-Gods are far too numerous to be accounted for by any mere coincidence."[182]
