Protosebastos
The title of protosebastos (Greek: πρωτοσέβαστος, prōtosébastos, "first sebastos") was a high Byzantine court title created by Emperor Alexios I Komnenos.
History
    
Although the title first appears in a document of 1049, where Domenico I Contarini, the Doge of Venice, uses it alongside the title of patrikios to refer to himself, it is commonly accepted that it was created by Emperor Alexios I Komnenos (r. 1081–1118).[1] It was first conferred to his brother Adrianos,[2] while another early holder, his brother-in-law Michael Taronites, was soon after raised to the even higher title of panhypersebastos.[1] It was also conferred on Sergius VI of Naples and his son, John VI, at about the same time.[3]
Later, during the 12th century, it was given to close relatives of the Byzantine emperor, such as the eldest son of a sebastokratōr.[4] In the Palaiologan period it was conferred to leading aristocratic families, such as the Tarchaneiotai, the Raoul, etc.[1]
The Book on Offices by Pseudo-Kodinos, written shortly after the middle of the 14th century, places the prōtosebastos in the thirteenth place in the overall hierarchy after the emperor, between the megas logothetēs and the pinkernēs.[5] His ceremonial costume comprised a golden-green skiadion hat with silk embroideries, or a domed skaranikon in a reddish apricot colour decorated with gold-wire embroidery, with a painted glass depiction of the emperor standing in front, and enthroned in the rear. A rich silk kabbadion tunic was also worn.[6]
