The
Late Roman army in the late 3rd century continued to use the insignia usual to the
Roman legions: the eagle-tipped
aquila, the square
vexillum, and the
imago (the bust of the emperor on a pole). In addition, the use of the
draco, adopted from the
Dacians, was widespread among cavalry and
auxiliary units. Few of them seem to have survived beyond the 4th century, however. The
aquila fell out of use with the breaking up of the old legions, the
imago was abandoned with the adoption of
Christianity, and only the
vexillum and the
draco are still occasionally attested in the 5th century and beyond.
Constantine the Great (r. 306–337) inserted the
Chi-Rho emblem in Roman military standards, resulting in the so-called
labarum. In iconographical evidence, this commonly takes the form of the
Chi-Rho embroidered on the field of a
vexillum, but literary evidence suggests also its use as a symbol at the head of a staff. The
labarum, although common in the 4th and 5th centuries, vanishes entirely in the 6th, and reappears only much later in altered form as part of the imperial regalia. In the late 6th-century
Stratēgikon attributed to Emperor
Maurice, two kinds of military flags appear: the triangular pennon or
phlamoulon (φλάμουλον, from , "little flame"), and the larger
bandon (βάνδον, from Latin and ultimately
Germanic bandum). The pennons were used for decorative purposes on lances, but the
Stratēgikon recommends removing them before battle. According to literary evidence, they were single or double-tailed, while later manuscript illuminations evidence triple-tailed
phlamoula. The
bandon was the main Byzantine battle standard from the 6th century on, and came even to give its name to the basic Byzantine army unit (
bandon or
tagma). Its origin and evolution are unknown. It may have resulted from modifications to the
draco or the
vexillum, but it appears in its final form in the
Stratēgikon, composed of a square or rectangular field with streamers attached. Illuminated chronicles, such as the
Madrid Skylitzes, often depict flags conforming to the general
bandon type in various colours and designs, but their accuracy is doubtful. While they may give a good general idea of how flags looked like, the flags themselves are "simplified and schematised", and the illustrators do not bother to differentiate between the flags shown for the Byzantines and for their enemies; even the
Saracens are shown as flying a flag topped with a cross. The historian A. Babuin furthermore notes that the flags shown in the manuscript vary widely in appearance and that no singular pattern can be discerned, apart from a relatively restricted range of colours (red, white, and blue) used either monochromatically or in alternating bands. In addition, the "considerable length of the streamers" shown in the manuscript does not appear in similar sources from areas under direct Byzantine control, but reflects iconography common in southern Italy, where the manuscript was illuminated.

Historical re-enactors of Byzantine soldiers, with flags inspired by the
Madrid Skylitzes According to the
Stratēgikon, the colours of the standard reflected a unit's hierarchical subordination: the
banda of the regiments of the same brigade (
moira,
droungos) had a field of the same colour, distinguished by a distinctive device, and the regiments of the same division (
meros or
tourma) of the army had the same colour on their streamers. Each
moira and
meros also had their own flag, as well as the army's commanding general (
stratēgos). These were on the same pattern but of larger size, and possibly with more streamers (the
Stratēgikon depicts flags with two to eight streamers). Maurice further recommends that the flag of the centre
meros, led by the deputy commander (
hypostratēgos), should be more conspicuous than those of the other
merē, and that the flag of the commanding general (or the emperor, if he was present) should be the most conspicuous of all. In addition, the
Stratēgikon prescribes a separate standard for the baggage train (
touldon) of each
moira. The standards were not only used for distinguishing units, but also as rallying points and for conveying signals to the other formations. In the
Byzantine navy, likewise, each ship had its own standard. As with their land counterparts, they were also used to convey signals. In the 10th century, the cross became a more prominent symbol, and was often used as a
finial instead of a spear point. Under
Nikephoros II Phokas (r. 963–969) large crosses of gold and jewels were used as standards, perhaps carried on a pole or otherwise displayed on the flags. In addition, the use of pieces of the
True Cross is often mentioned in military parades. In the late Byzantine period, pseudo-Kodinos records the use of the Palaiologan "tetragrammatic cross" (see above) on the imperial ensign (,
basilikon phlamoulon) borne by Byzantine naval vessels, while the navy's commander, the
megas doux, displayed an image of the emperor on horseback. == Ceremonial insignia ==
