[1][2] Officials in charge of administration were thus designated ὁ ἐπὶ τῇ διοικήσει (ho epi tē dioikēsei).
[2] The title of dioikētēs is mostly attested in Ptolemaic Egypt, where it was held by the head of the kingdom's financial administration, headquartered in the capital Alexandria.
[5] The dioikētai of this period were subordinate officials of the logothetēs tou genikou, the head of the "general" (genikon) fiscal department, and detailed to provincial duties.
From their surviving seals, both the older Late Roman civil provinces as well as the newer theme are attested, but most of the dioikētai were sent to individual islands or—mostly coastal—cities.
[5] Modern scholarship suggests that the dioikētai were rewarded by the practice known as synētheia, a fee representing a fixed portion of the taxes they raised.
