Theodora Doukaina was the second daughter of Byzantine emperor Constantine X Dukas by his unknown first wife. After 1071 she became the wife of Domenico Selvo, Doge of Venice, who received the title of protoproedros at the occasion.
Confusion with Maria ArgyropoulainaEdit
Peter Damian, the Cardinal Bishop of Ostia, wrote a chapter entitled "De Veneti ducis uxore quae prius nimium delicata, demum toto corpore computruit" ("Of the Venetian Doge's wife, whose body, after her excessive delicacy, entirely rotted away.") about an unnamed Byzantine princess whose manners he considered scandalously lavish and which brought to her a horrible death as a divine punishment. This woman has been mistakenly (since Damian died 1072) identified with Domenico Selvo's wife by later Venetian chroniclers (incl. Andrea Dandolo and Marino Sanudo the Younger) followed afterwards by various modern authors; however since the work in which Damianus' chapter is contained is dated ca 1059 it refers probably to Maria Argyropoulaina who had died a half century before.

Nor did she deign to touch her food with her fingers, but would command her eunuchs to cut it up into small pieces, which she would impale on a certain golden instrument with two prongs and thus carry to her mouth. Her rooms, too, were so heavy with incense and various perfumes (...)" (Damianus as cited by Norwich, John Julius (1982). A history of Venice (1st American ed.). New York: Knopf. ISBN 0394524101.
