Logothete (Greek: λογοθέτης, logothétēs, pl. λογοθέται, logothétai; Med. Latin: logotheta, pl. logothetae; Bulgarian: логотет; Italian: logoteta; Romanian: logofăt; Serbian: логотет, logotet) was an administrative title originating in the eastern Roman Empire. In the middle and late Byzantine Empire, it rose to become a senior , equivalent to a minister or secretary of state. The title spread to other states influenced by Byzantine culture, such as Bulgaria, Sicily, Serbia, and the Danubian Principalities.
In Greek, logothetēs means "one who accounts, calculates or ratiocinates", literally "one who sets the word". The exact origin of the title is unclear; it is found in papyri and works of the Church Fathers denoting a variety of junior officials, mostly charged with fiscal duties. The ancestors of the middle Byzantine logothetes were the fiscal officials known as rationales during Late Antiquity. The office dates back to at least the time of Emperor Septimius Severus (r. 193–211), where a procurator a rationibus is attested. In late Roman times, the rationales were officials attached to the praetorian prefectures and charged with supervising the state treasury and the emperor's private domains. The first notable official titled as a logothete was Marinus, the future praetorian prefect and chief minister of Emperor Anastasius I (r. 491–518). In the 6th century, under Emperor Justinian I (r. 527–565), the logothetes gained in prominence and power, as they were placed in charge of the emperor's revenue-gathering measures and dispatched as fiscal agents to the provinces or accompanied military expeditions. They were allowed to keep a twelfth of the sums they would gather for the treasury, and some, such as the notorious Alexander "Scissors", amassed considerable fortunes in this way.
