Count of the Stable

The Count of the Stable (comes stabuli; κόμης τοῦ σταύλου/στάβλου, komēs tou staulou/stablou) was a late Roman and Byzantine office responsible for the horses and pack animals intended for use by the army and the imperial court. From Byzantium, it was adopted by the Franks, and is the origin of the post and title of constable, via the Old French conestable.

History and functions
The post first appears in the 4th century as the tribunus [sacri] stabuli ("tribune of the [sacred] stable"), initially responsible for the levying of horses from the provinces. According to Ammianus Marcellinus, they ranked equal to the tribunes of the Scholae Palatinae guard regiments. In the Notitia Dignitatum, they are listed as the praepositi gregum et stabulorum under the comes rerum privatarum. By the early 5th century, as attested in the Codex Theodosianus, they were raised to comites with the rank of vir clarissimus, but the older title of tribune remained in parallel use for some time (cf. Cod. Theod., 6.13.1).

Eight holders of the office are known from the 4th century, including Emperor Valens (r. 364–378) and his brothers-in-law Cerealis and Constantinianus. Evidently, the post was closely associated with the imperial family. Thus, Stilicho was appointed to it when he married the adopted niece of Emperor Theodosius I (r. 378–395), Serena. However, holders are rarely mentioned thereafter. The great general Flavius Aetius held the post in 451, and in the 6th century, the variant "Count of the Imperial Grooms" was conferred on leading generals such as Belisarius and Constantinianus, while Baduarius, a relative of Emperor Justin II (r. 565–578), is recorded by the 9th-century chronicler Theophanes the Confessor to have held the post of Count of the Imperial Stables. The office reappears in the sources in the 820s, when the "prōtospatharios and komēs tou basilikou hippostasiou" Damian led an unsuccessful expedition against the Arabs in Crete.

The Byzantine office of the komēs tou staulou is best known during the 9th and 10th centuries, when it was classed as belonging to the group of military officials known as stratarchai. Along with the Logothete of the Herds (logothetēs tōn agelōn), he was responsible for the imperial horses in the capital, Constantinople, and for the horse ranches in the great army camp (aplēkton) at Malagina in Bithynia. He usually held the dignity of patrikios, and ranked 51st in the overall imperial hierarchy. During imperial processions, as well as during war, he escorted the Byzantine emperor along with the prōtostratōr, and played a role in the receptions of foreign ambassadors.

In the 13th century, the Latin-inspired office of the konostaulos seems to have replaced the komēs tou staulou, but another title, the komēs tōn basilikōn hippōn (Greek: κόμης τῶν βασιλικῶν ἴππων, "count of the imperial horses") appears in the 14th-century treatise on offices of Pseudo-Kodinos. Aside from bringing the Byzantine emperor his horse and holding it while he mounted it, the functions of this office are unknown. He does not appear to have held a rank within the court hierarchy, but his proximity to the Byzantine emperor did apparently lead to some influence, as in the case of Constantine Chadenos, who rose from this post to high political offices under Emperor Michael VIII (r. 1259–1282).

Subordinate officials
The staff (officium) of the Count of the Stable is not explicitly mentioned in Byzantine sources, but its composition for the 9th and 10th centuries can be inferred, at least in part. It included:


 * Two chartoularioi, one for Constantinople (Greek: ὁ ἔσω χαρτουλάριος, "the inner chartoularios") and one for Malagina (Greek: ὁ χαρτουλάριος τῶν Μαλαγίνων or ὁ ἔξω χαρτουλάριος, "the outer" or "provincial" chartoularios").


 * The epeiktes, in seals often epiktes (Greek: ἐπ[ε]ίκτης, according to John Bagnell Bury "an overseer who presses work on"), responsible for fodder, watering, and other related supplies like horseshoes or saddles.


 * The saphramentarios (Greek: σαφραμεντάριος), the origin of whose title and his functions are unknown. In the sources, he seems to be responsible for outfitting the imperial mules prior to an expedition.


 * The four counts (komētes) of Malagina (Greek: οἱ δ′ κόμητες τῶν Μαλαγίνων).


 * Forty grooms (Greek: οἱ μ′ σύντροφοι τῶν σελλαρίων), also known as the "grooms of the two stables" (Greek: οἱ σύντροφοι τῶν δύο στάβλων, i.e. Constantinople and Malagina). These were probably subaltern officers charged with leading detachments of mules.


 * The kellarios (Greek: κελλάριος) or apothetēs (Greek: ἀποθέτης) of the imperial stable, responsible for the stables' granary.
