Protosebastos

The title of protosebastos (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)). It was first conferred to his brother Adrianos, while another early holder, his brother-in-law Michael Taronites, was soon after raised to the even higher title of panhypersebastos. It was also conferred on Sergius VI of Naples and his son, John VI, at about the same time.

Later, during the 12th century, it was given to close relatives of the Byzantine emperor, such as the eldest son of a sebastokratōr. In the Palaiologan period it was conferred to leading aristocratic families, such as the Tarchaneiotai, the Raoul, etc.

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. 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.
