Page "Quaestor" Paragraph 11

During Late Antiquity, the office of quaestor sacri palatii existed, created by Constantine the Great, which functioned as the Roman Empire's senior legal official.

Emperor Justinian I also created the offices of quaesitor, a judicial and police official for Constantinople, and the quaestor exercitus, a short-lived joint military-administrative post covering the border of the lower Danube.

The quaestor sacri palatii survived long in the Byzantine Empire, albeit with his duties altered to coincide with those of the quaesitor.

The term is last attested in Byzantium in the 14th century, as a purely honorific dignity.
