'accountant') was a type of financial official in the Byzantine Empire from the early 11th century onwards, with the task of controlling expenses.
[1] Emperor Alexios I Komnenos (r. 1081–1118) created the post of megas logariastes (μέγας λογαριαστής, 'grand accountant'), first attested in 1094.
[1] In the mid-14th century Book of Offices of pseudo-Kodinos, the megas logariastes is ranked 40th in the palace hierarchy, following the logothetes ton oikeiakon and preceding the protokynegos.
[2] The costume of office was identical to that of the logothetes ton oikeiakon, i.e. a turban (phakeolis) and the epilourikon,[3] probably a descendant of the middle Byzantine epilorikon, a garment worn over armour.
[4] In the 14th century, the special post of the logariastes tes aules (λογαριαστὴς τῆς αὐλῆς, 'accountant of the court') is attested, responsible for paying the salaries of certain courtiers.
