Theoktiste (Greek: Θεοκτίστη), also known as Phlorina (Φλώρινα), was the mother of the 9th-century Byzantine empress Theodora, the wife of Emperor Theophilos.
Theoktiste Phlorina was the spouse of Marinos, an officer in the Byzantine army with the rank of tourmarches or droungarios.
[2] Some modern genealogists, including Cyril Toumanoff and Nicholas Adontz, have suggested that Marinos hailed from the Armenian noble clan of the Mamikonian.
"[3] With Marinos, Theoktiste had two sons, Bardas and Petronas, and four daughters, Theodora, Sophia, Maria and Irene.
[2][4] In 821 or 830 (the date is disputed), Theodora married Theophilos, who in 829 succeeded his father Michael II the Amorian (ruled 820–829) as emperor.
