Eventually, with the waning of Byzantine power in the region, these rulers took on more familiar Latin titles like "consul" and "dux", modern duke. The most famous "hypatoi" were those of Gaeta. John I of Gaeta won the title "patrikios" from the Byzantine emperor, as a reward for defeating the Saracens. In Gaeta, the feminine title "hypatissa" () was replaced by "doúkissa" (Italian: "ducissa") during the reign of Docibilis II of Gaeta and his wife Orania, in the first half of the 10th century. The title was the root of the titles "anthypatos" ("vice-"hypatos"", the translation of proconsul) and "dishypatos" ("twice "hypatos""), as well as the office of "hypatos tōn philosophōn" (, "chief of the philosophers"), a title given to the head of the imperial university of Constantinople in the 11th-14th centuries.
