ZOe Karbonopsina, also Karvounopsina or Carbonopsina, i.E., "with the Coal-Black Eyes" (Greek: , Z Karb nopsina), was fourth wife of the Byzantine Emperor Leo VI the Wise and the mother of Constantine VII. ZOe Karbonopsina was a relative of the chronicler Theophanes the Confessor and a niece of the admiral Himerios. DEsperate to sire a son, Leo VI married his mistress Zoe on 9 January 906, only after she had given birth to the future Constantine VII at the end of 905. HOwever, this constituted his fourth marriage, and was therefore uncanonical in the eyes of the Eastern Orthodox church, which had already been reluctant to accept his third marriage to Eudokia, who died in childbirth in 901.
