Sol Invictus ("Invincible Sun") was the official sun god of
the later Roman Empire. In 274 Aurelian made it an official cult alongside the
traditional Roman cults. Scholars disagree whether the new deity was a
refoundation of the ancient Latin cult of Sol a revival of the cult of Elagabalus or completely new. The god was favored
by emperors after Aurelian and appeared on their coins until Constantine. The last
inscription referring to Sol Invictus dates to 387 AD and there were enough
devotees in the 5th century that Augustine found it necessary to preach against
them. A
festival (the Dies Natalis Solis Invicti or birthday of Sol Invictus) on
25 December is thought to be responsible for the date of Christmas.
Invictus (unconquered) was an epithet used for various Roman
divinities in the Roman Empire. In the Roman Calendar of the early empire these
include
Jupiter Invictus and
Mars Invictus.
It was in use from the late Republic and throughout the Imperial period for a
range of deities, such as Hercules, Apollo and Silvanus, and was therefore a
well-established form when applied to Mithras by Roman devotees from the 2nd
century onwards. It has a clear association with solar deities and solar
monism; as such, it became the preferred epithet of Rome's traditional Sol and
the novel, short-lived Roman state cult to Elagabalus, an Emesan solar deity
who headed Rome's official pantheon under his namesake emperor.
The earliest dated use of Sol invictus is in a dedication from Rome,
AD 158. Another, stylistically dated to the 2nd century AD, is inscribed on a
Roman phalera: "inventori lucis soli invicto augusto"
(to the contriver of light, sol invictus augustus ). Here "augustus"
is most likely a further epithet of Sol as "august" (an elevated
being, divine or close to divinity), though the association of Sol with the
Imperial house would have been unmistakable and was already established in
iconography and stoic monism. These are the earliest attested examples of Sol
as invictus, but in AD 102 a certain Anicetus restored a shrine of Sol;
Hijmans (2009, 486, n. 22) is tempted "to link Anicetus' predilection for
Sol with his name, the Latinized form of the Greek word ἀνίκητος, which means invictus".
Elagabalus:
The first sun god consistently
termed invictus was the provincial
Syrian god Elagabalus.
According to the Historia Augusta, the teenaged Severan heir adopted the
name of his deity and brought his cult image from Emesa to Rome. Once installed
as emperor, he neglected Rome's traditional State deities and promoted his own
as Rome's most powerful deity. This ended with his murder in 222.
The Historia Augusta refers
to the deity Elagabalus as "also called Jupiter and Sol" (fuit
autem Heliogabali vel Iovis vel Solis).
This has been seen as an abortive
attempt to impose the Syrian sun god on Rome; but because it is now clear that the Roman
cult of Sol remained firmly established in Rome throughout the Roman period,
this Syrian Sol Elagabalus has
become no more relevant to our understanding of the Roman Sol than, for example, the Syrian Jupiter Dolichenus
is for our understanding of the Roman Jupiter.
Aurelian:

Rome, 274–275
The Roman gens Aurelia was associated with
the cult of Sol After his victories in the East, the emperor Aurelian thoroughly reformed the Roman cult of Sol,
elevating the sun-god to one of the premier divinities of the empire. Where
previously priests of Sol had been simply sacerdotes and tended to belong to lower
ranks of Roman society, they were now pontifices and members of the new college of pontifices
instituted by Aurelian. Every pontifex of Sol was a member of the senatorial
elite, indicating that the priesthood of Sol was now highly prestigious. Almost
all these senators held other priesthoods as well, however, and some of these
other priesthoods take precedence in the inscriptions in which they are listed,
suggesting that they were considered more prestigious than the priesthood of
Sol. Aurelian also built a new temple for Sol, bringing the total number of
temples for the god in Rome to (at least) four. He also instituted games in
honor of the sun god, held every four years from AD 274 onwards.
The confusion surrounding Aurelian's
reforms has been significant, much of it rooted in the mistaken opinion that he
was introducing a new cult, which, as is now clear, he was not. The following
constitute the most common errors of fact attributed to Aurelian and his
reforms.
1. Aurelian called his sun god Sol Invictus
to differentiate him from the earlier Roman god Sol.
Actually, Aurelian is twice as
likely to call Sol Oriens on his coins as he is Sol Invictus.
Only one of the fifteen or so pontifices of Sol adds the epithet invictus;
all others simply call themselves "pontifex Solis".
2. Aurelian built his new temple for
a Syrian sun god, not the Roman one.
There is no credible evidence to
support this, and ample evidence to refute it. The "Syrian
Sol-hypothesis" is therefore now rejected by all specialists in the field.
3. Aurelian inaugurated his new
temple dedicated to Sol Invictus and held the first games for Sol on December
25, 274, on the supposed day of the winter solstice and
day of rebirth of the Sun.
This is not only pure conjecture,
but goes against the best evidence available. There is no record of celebrating
Sol on December 25 prior to AD 354/362. Hijmans lists the known festivals of
Sol as August 8 and/or 9, August 28, and December 11. There are no sources that
indicate on which day Aurelian inaugurated his temple and held the first games
for Sol, but we do know that these games were held every four years from AD 274
onwards. This means that they were presumably held in AD 354, a year for which
perchance a Roman calendar, the Chronography of 354
(or calendar of Filocalus), has survived. This calendar lists a festival for
Sol and Luna on August 28, Ludi
Solis (games for Sol) for October 19–22, and a Natalis Invicti
(birthday of the invincible one) on December 25. While it is widely assumed
that the invictus of December 25 is Sol, the calendar does not state
this explicitly. The only explicit reference to a celebration of Sol in late
December is made by Julian the Apostate
in his hymn to King Helios written immediately afterwards in early AD 363.
Julian explicitly differentiates between the one-day, annual celebration of
late December 362 and the multi-day quadrennial games of Sol which, of course,
had also been held in 362, but clearly at a different time. Taken together, the
evidence of the Calendar of Filocalus and Julian's hymn to Helios clearly
shows, according to Hijmans and others, that the ludi of October 19–22 were
the Solar Games instituted by Aurelian. They presumably coincided with the
dedication of his new temple for Sol.
4. After Aurelian, Sol became
supreme deity of the Roman Empire.
(Hijmans 2009,
chapter 9) raises serious doubts about this contention.
Constantine:
Emperors portrayed Sol Invictus on
their official coinage, with a wide range of legends, only a few of which
incorporated the epithet invictus, such as the legend SOLI INVICTO COMITI,
claiming the Unconquered Sun as a companion to the Emperor, used with
particular frequency by Constantine. Statuettes of Sol Invictus, carried by the
standard-bearers, appear in three places in reliefs on the Arch of Constantine.
Constantine's official coinage continues to bear images of Sol until 325/6. A solidus of Constantine as well as a gold medallion from
his reign depict the Emperor's bust in profile twinned ("jugate")
with Sol Invictus, with the legend INVICTUS
CONSTANTINUS.
Constantine decreed (March 7, 321) dies
Solis—day of the sun, "Sunday"—as
the Roman day of rest [CJ3.12.2]:
On the venerable day of the Sun let the magistrates and
people residing in cities rest, and let all workshops be closed. In the country
however persons engaged in agriculture may freely and lawfully continue their
pursuits because it often happens that another day is not suitable for
grain-sowing or vine planting; lest by neglecting the proper moment for such
operations the bounty of heaven should be lost.
Constantine's triumphal arch was
carefully positioned to align with the colossal statue of Sol
by the Colosseum, so that Sol formed the dominant backdrop
when seen from the direction of the main approach towards the arch.
Sol And The Other Roman Emperors:
Berrens
[ deals
with coin-evidence of Imperial connection to the Solar cult. Sol is depicted
sporadically on imperial coins in the 1st and 2nd centuries AD, then more
frequently from
Septimius Severus onwards until AD 325/6.
Sol
invictus appears on coin legends from AD 261, well before the reign of
Aurelian.
Connections between the imperial radiate crown and the cult of Sol are
postulated.
Augustus was posthumously depicted with radiate crown,
as were living emperors from
Nero
(after AD 65) to
Constantine. Some modern scholarship interprets the
imperial radiate crown as a divine, solar association rather than an overt
symbol of Sol; Bergmann calls it a pseudo-object designed to disguise the
divine and solar connotations that would otherwise be politically controversial
but there is broad agreement that coin-images showing the imperial radiate
crown are stylistically distinct from those of the solar crown of rays; the
imperial radiate crown is depicted as a real object rather than as symbolic
light.
Hijmans argues that the Imperial
radiate crown represents the honorary wreath awarded to
Augustus, perhaps posthumously, to
commemorate his victory at the
battle of Actium; he points out that henceforth, living
emperors were depicted with radiate crowns, but state
divi were not. To
Hijmans this implies the radiate crown of living emperors as a link to
Augustus. His successors automatically inherited (or sometimes acquired) the
same offices and honours due to Octavian as "saviour of the Republic"
through his victory at Actium, piously attributed to Apollo-Helios. Wreaths
awarded to victors at the Actian Games were radiate.
Sol Invictus
And Sunday:
One day of the week was named after Sol, the sun. In honor of the Sun god,
many merchants elected to pay their workers weekly upon this day. However, the
Roman observance was quite different from that of the Jewish observance of
Saturday or the Christian Sabbath. The first Sunday closing law was enacted by
Constantine in 321 AD, and refers to the "day of the sun". It forms
the basis of subsequent Christian legislation in this area.
Sol Invictus And Christianity:
The Philocalian calendar
of 354 AD gives a festival of "Natalis Invicti" on 25 December. There
is limited evidence that this festival was celebrated before the mid 4th
century AD.
Whether the 'Sol Invictus' festival
"has a strong claim on the responsibility for our December date" of Christmas (as per the 1908 Catholic Encyclopedia)
or not has been called into question by Joseph Cardinal Ratzinger, now Pope Benedict XVI, who challenged this theory by arguing
that a December 25 date was determined simply by calculating nine months beyond
March 25, regarded as the day of Jesus’ conception (the Feast of the Annunciation).
In the 5th century, Pope Leo I (the Great) spoke of how the celebration of
Christ's birth coincided with the sun's position increasing in the sky in
several sermons on the Feast of the Nativity. Here is an excerpt from his 26th sermon:
But this Nativity which is to be
adored in heaven and on earth is suggested to us by no day more than this when,
with the early light still shedding its rays on nature, there is borne in upon
our senses the brightness of this wondrous mystery.
"Besides, the Sol Invictus had been adopted by the
Christians in a Christian sense, as demonstrated in the Christ as Apollo-Helios
in a mausoleum (c. 250) discovered beneath St. Peter's in the Vatican."
Indeed "...from the beginning of the 3rd century "Sun of
Justice" appears as a title of Christ".
Some consider this to be in
opposition to Sol Invictus Some see an allusion to Malachi 4:2.
"It was a custom of the Pagans to celebrate on the same
25 December the birthday of the Sun, at which they kindled lights in token of
festivity. In these solemnities and revelries the Christians also took part.
Accordingly when the doctors of the Church perceived that the Christians had a
leaning to this festival, they took counsel and resolved that the true Nativity
should be solemnised on that day."
