Origin and early use The term first appears in the late 1st century BC in the
Hellenistic Near East. Its origin is unclear, but it is used as a translation, in some inscriptions, for the contemporary
Roman legionary post of ().
Josephus (
De Bello Judaico, VI.238) uses the term to refer to the
quartermaster-general of all camps, while
Dionysius of Halicarnassus (
Roman Antiquities, X.36.6) used it to refer to the role of a in a
legion that had lost its commander. It also occurs in the
Bible (), where it has been interpreted as referring to the
praetorian prefect, the commander of the camp and
garrison of the
Praetorian Guard in
Rome, or the subordinate officials and . From the 1st century AD, it was used (albeit infrequently) in a broader sense as a literary term to refer to generals, i.e. as a synonym of the older title . Thus in the 4th century, the bishop and historian
Eusebius (
Church History, IX.5.2) writes of the ", whom the Romans call ". Similarly, in the early 5th century,
Ardabur was called " of both forces" by
Olympiodorus of Thebes, while the acts of the
Council of Chalcedon (451) refer to
Zeno, " and of both forces of the East". This is an obvious translation of the Latin term , especially as the contemporary historian
Eunapius records that the was "the greatest of offices". Other Greek-language authors translate Ardabur's title more commonly with or . The Swiss historian
Albert Vogt suggested that the were military
intendants, responsible for army supplies and managing the fortified assembly bases, the . However, as the
Byzantinist Rodolphe Guilland commented, references to a are rare before the 10th century, and always seem to be a different way of referring—often
anachronistically—to a , or later a
thematic . Such references exist to emperor
Jovian (), who was a general before his rise to the throne, by
Theophanes the Confessor; Rusticius, a general of
Leo I (), by
Zonaras; Busur, an Arab commander in , by Theophanes; Krateros, a " of the East" who was sent to arrest
Theodore Stoudites; Eudokimos, / of
Cappadocia and
Charsianon under
Theophilos (); and a certain Mousilikes, subordinate of the thematic of
Sicily. A Constantine, whose seal mentions him as a , cannot be further identified.
Middle Byzantine period , , of the East, and of
Antioch In the middle
Byzantine period (9th–12th centuries), the term came to signify more the army on campaign, rather than the camp itself; hence the term was used more in the sense of 'commander-in-chief'. The title is first attested as a technical term in 967, when Emperor
Nikephoros II Phokas () named the
eunuch Peter as before sending him with an army to
Cilicia. The
Escorial Taktikon, written a few years later, shows the existence of two , one of the East (
Anatolia) and one of the West (the
Balkans). This arrangement parallels that of the two , a fact that led
Nicolas Oikonomides to suggest that the post was created as a substitute of the latter office, which was barred to eunuchs until the 11th century. The actual nature of the office is difficult to reconstruct, as it is rarely found in technical sources like the Byzantine military and court manuals, and its usage in the historical accounts is simply as another word for a high commander, in place of
or . Thus it is unclear what position the occupied vis-à-vis the , or why some officers received the former rather than the latter title. The precise arrangement suggested by Oikonomides is certainly not in evidence in the 11th and 12th centuries, when the term likely signified a commander-in-chief for a field army composed of professional regiments (), rather than an institutionalized position.
Late Byzantine period (), George Mouzalon's friend and patron The title '''''' ('grand master of the camp') was instituted by the Emperor
Theodore II Laskaris () for his chief minister and confidante,
George Mouzalon. Theodore II states in a decree that he "established the dignity anew", but no other holder of the office is known before that time. The mid-14th century
Book of Offices of
pseudo-Kodinos places the as the ninth-most senior official of the state below the Emperor, ranking between the and the . Kodinos reports that he was "supervisor of the provisioning of the army, that is food, drink and all necessities". In reality, however, during the
Palaiologan period (1261–1453) the was most likely an honorific court title, and did not necessarily entail an active military command. Like many other titles in the Palaiologan period, the post could be held by two people simultaneously. According to Pseudo-Kodinos, the ceremonial costume of the was identical to the offices immediately superior to it: a rich silk tunic, a golden-red hat decorated with embroideries in the style, without veil, or a domed hat, again in red and gold and decorated with golden wire, with a portrait of the emperor standing in front, and another of him enthroned in the rear. Only his staff of office () differed, with all the knobs except the topmost in silver, and golden engraved knots. Pseudo-Kodinos further reports the existence of four subordinate , occupying the 65th to 68th rank in the imperial hierarchy respectively. These were: • The of the (μονοκάβαλλοι, 'single-horsemen'). Kodinos explains that cavalry used to be raised in the themes according to the wealth of its owners, with the classes being , , and after the number of horses each rider provided; a system similar to that current in Western Europe at the time. • The of the (τζαγγράτορες, '
crossbow-men'). • The of the (μουρτάτοι). According to Kodinos these were palace guards armed with the bow. Their name is commonly held to derive from the Arabo-Turkish word
murted/murtat ('apostate'), implying they were Christianized Turks, but according to Mark Bartusis may refer more generally to the offspring of mixed Greek–Turkish unions. • The of the (τζάκωνες, '
Tsakonians'). The or (Λάκωνες, '
Laconians') had served as
marines since
Michael VIII Palaiologos. According to Kodinos, some served as palace guards, equipped with maces () and wearing with a distinctive blue cuirass that bore two white lions facing each other on the chest, but the supervised those who were employed as garrison troops in various fortresses. The dress of these junior members of the court was the same: a white with embroideries, a long of "commonly used silk", and a covered in red velvet and topped by a small red tassel. Their were of smooth, unadorned wood. The semi-autonomous
Despotate of the Morea appears to have had a and subordinate of its own. ==List of known ==
