It was designed by the Roman emperor Saint Constantine the Great after receiving his celestial vision and dream, on the eve of his victory at the Milvian Bridge in 313 AD. It was a vexillum (military standard/flag/banner) that displayed the "Chi-Rho" Christogram, which was formed from the first two Greek letters of the word "Christ" (Greek: ΧΡΙΣΤΟΣ, or Χριστός) — Chi (χ) and Rho (ρ), being one of the earliest forms of christogram used by Christians.
From 324 it was the official standard of the Roman Empire. Fashioned after legionary standards, it substituted the from of a cross for the old pagan symbols, surmounted by a jewelled wreath containing the monogram of Christ, intersecting Chi (χ) and Rho (ρ), on which hung a purple banner inscribed with "Εν Τουτω Νικα" (in hoc signo vinces) — "In this sign, conquer." As a new focal point for Roman unity, the monogram appeared on coins, shields, and later public buildings and churches.
The etymology of the Late Latin word labarum is uncertain, however it has been suggested that the word descended from the Greek láboron (λάβαρον - laurel-leaf standard),[note 1] which in turn renders the Latin Laureum Vexillum, literally "laureled standard".
In a similar but slightly different conclusion, the American Heritage Dictionary of the English Language (4th ed.) states that labarum is Late Latin, probably being an alteration of the Greek labraton ("laurel-leaf standard"), which is itself derived from the Latin Laureatum (the neuter of Laureatus - "crowned/adorned with laurel").
It may also be derived from the Latin /labāre/ 'to totter, to waver', in the sense of the "waving" of a flag in the breeze.
Other proposals include a derivation from the Celtic llafar ("eloquent"), or from the ancient Cantabri dialect labaro ('four heads'),[note 2] an ancient Celtic symbol taken by the Legions during the Cantabrian Wars.
Vision of Constantine
It is commonly stated that on the evening of October 27, 312, with his army preparing for the Battle of the Milvian Bridge, the emperor Constantine I had a vision which led him to fight under the protection of the Christian God. The details of that vision, however, differ between the sources reporting it, namely Lactantius and Eusebius.
Lactantius states that, in the night before the battle, Constantine was commanded in a dream to "delineate the heavenly sign on the shields of his soldiers". He obeyed and marked the shields with a sign "denoting Christ". Lactantius describes that sign as a "staurogram", or a Latin cross with its upper end rounded in a P-like fashion. There is no certain evidence that Constantine ever used that sign, rather than the better known Chi-Rho sign described by Eusebius of Caesarea.
From Eusebius, two accounts of the battle survive. The first, shorter one in the Ecclesiastical History leaves no doubt that God helped Constantine but doesn't mention any vision. In his later Life of Constantine, Eusebius gives a detailed account of a vision and stresses that he had heard the story from the emperor himself. According to this version, Constantine with his army was marching somewhere[note 3] when he looked up to the sun and saw a cross of light above it, and with it the Greek words: "Εν Τουτω Νικα" (Latin: in hoc signo vinces — "In this sign, conquer"). At first he was unsure of the meaning of the apparition, but the following night he had a dream in which Christ explained to him that he should use the sign against his enemies. Eusebius then continues to describe the labarum, the military standard used by Constantine in his later wars against Licinius, showing the Chi-Rho sign.
Eusebius' Description of the Labarum
"A Description of the Standard of the Cross, which the Romans now call the Labarum."
"Now it was made in the following manner. A long spear, overlaid with gold, formed the figure of the cross by means of a transverse bar laid over it. On the top of the whole was fixed a wreath of gold and precious stones; and within this, the symbol of the Saviour’s name, two letters indicating the name of Christ by means of its initial characters, the letter P being intersected by X in its centre: and these letters the emperor was in the habit of wearing on his helmet at a later period. From the cross-bar of the spear was suspended a cloth, a royal piece, covered with a profuse embroidery of most brilliant precious stones; and which, being also richly interlaced with gold, presented an indescribable degree of beauty to the beholder. This banner was of a square form, and the upright staff, whose lower section was of great length, of the pious emperor and his children on its upper part, beneath the trophy of the cross, and immediately above the embroidered banner." "The emperor constantly made use of this sign of salvation as a safeguard against every adverse and hostile power, and commanded that others similar to it should be carried at the head of all his armies."
Historical Evidence for Use of the Labarum
Historians contend that those two accounts can hardly be reconciled with each other, though they have been merged in popular notion into Constantine seeing the Chi-Rho sign on the evening before the battle.
There is no certain evidence of the use of the letters chi and rho as a Christian sign before Constantine. Its first appearance is on a Constantinian silver coin from ca. 317, which proves that Constantine did use the sign at that time, though not very prominently. He made extensive use of the Chi-Rho and the labarum only later in the conflict with Licinius.
In the course of Constantine's second war against Licinius in 324, the latter developed a superstitious dread of Constantine's standard. During the attack of Constantine's troops at the Battle of Adrianople the guard of the labarum standard were directed to move it to any part of the field where his soldiers seemed to be faltering. The appearance of this talismanic object appeared to embolden Constantine's troops and dismay those of Licinius. At the final battle of the war, the Battle of Chrysopolis, Licinius, though prominently displaying the images of Rome's pagan pantheon on his own battle line, forbade his troops from actively attacking the labarum, or even looking at it directly.
Eusebius stated that in addition to the singular labarum of Constantine, other similar standards (labara) were issued to the Roman army. This is confirmed by the two labara depicted being held by a soldier on a coin of Vetranio dating from 350.
Later usage has sometimes regarded the terms "labarum" and "Chi-Rho" as synonyms (i.e. the labarum bearing the chi-rho symbol). Ancient sources however draw an unambiguous distinction between the two. For one thing this is because the "Chi-Rho" Christogram and the "Labarum" were not originally synonyms; originally, the labarum being a type of vexillum, was a military standard used in the Classical Era of the Roman Empire, with a flag hanging from a horizontal crossbar; the Chi-Rho Christogram was only added to the flag by the Emperor Constantine I in the late Roman period.
In addition, the "Chi-Rho" Christogram was not always used is connection with the imperial labarum, but its use by Christians naturally evolved into a variety of formats, including its use on coins and medallions (minted during Constantine's reign and by subsequent rulers), on Christian sarcophagi and frescoes from about 350 AD, and became part of the official imperial insignia after Constantine, eventually appearing on public buildings and churches as well.
A later Byzantine manuscript indicates that a jewelled labarum standard believed to have been that of Constantine was preserved for centuries, as an object of great veneration, in the imperial treasury at Constantinople. The labarum, with minor variations in its form, was widely used by the Christian Roman emperors who followed Constantine I.
A miniature version of the labarum became part of the imperial regalia of Byzantine rulers, who were often depicted carrying it in their right hands.
In the Middle Ages the pastoral staff of a bishop often had attached to it a small purple scarf known as the vexillum, supposedly derived from the labarum.
In Greece, the "Holy Lavara" were a set of early national Greek flags, blessed by the Greek Orthodox Church. Under these banners the Greeks united throughout the Greek War of Independence (1821-32), a war of liberation waged against the Ottoman Empire.[note 4]
Today, the term "labarum" is generally used for any ecclesiastical banner, such as those carried in religious processions.

- ↑ The similar Greek term "Lavra" has a different etymology. In Orthodox Christianity and certain other Eastern Christian communities Lavra or Laura (Greek: Λαύρα; Cyrillic: Ла́вра) originally meant a cluster of cells or caves for hermits, with a church and sometimes a refectory at the center (for example, Agia Lavra monastery in Greece). The term originates from Ancient Greek, where it means "a passage" or "an alley".

- ↑ Eusebius doesn't specify the actual location of the event, but it clearly isn't in the camp at Rome.
- ↑ The blessing of the standards recalls Constantine's use of the Labarum with the Chi-Rho Christogram before his battle with Maxentius at the Milvian Bridge, just over 1500 years earlier.
