The facts regarding Constantine's life are confused and subject to conjecture. It is known that at the time of Emperor Leo VI the Wise, he restored a monastery near the Church of the Holy Apostles, which is nowadays identified with the Fenari Isa Mosque on account of a partial inscription commemorating its dedication to the Theotokos. The date of the inauguration is traditionally placed in 907/908. Constantine Lips also participated in the failed coup of the prominent general Constantine Doukas against the infant Constantine VII Porphyrogennetos in July 913, after the death of Leo's brother and successor Alexander. In its wake, several nobles who had been or were suspected of being involved in the coup were executed, while others fledthe city, amongst them Constantine Lips. On August 20, 917, he fell at the Battle of Acheloos, fighting against the Bulgarian forces under Simeon I. He is also equated by modern scholarship with two other people named Lips, whose activities are believed to have been erroneously post-dated. The first is recorded by Constantine VII as having been held the rank of protospatharios and the court post of domestikos of the hypourgia, later rising to become a patrikios and megas hetaireiarches. He also served on several occasions as imperial envoy to Gregory I, the ruler of the Armenian principality of Taron. On the first embassy, he returned with Gregory's son Ashot, who was received by Leo and named protospatharios. Lips accompanied Ashot back to his father, and returned with Gregory's brother, who was also given the rank of protospatharios. Constantine accompanied Abu Ghanim on his return journey. When the latter visited Constantinople again some years later, he was married to Constantine's daughter. In another mission shortly after, Lips persuadedGregory himself to visit Constantinople, where he was lavishly received and given the supreme dignity of magistros and the title of strategos of Taron. After a prolonged sojourn, he was escorted to his domains by Lips. The later Patria of Constantinople also refer to a Lips, patrikios and Droungarios of the Fleet, who established a monastery and a guest house during the late reign of Constantine VII, but it is impossible to tell with certainty whether this is the same person. Constantine Lips had a son, the patrikios Bardas Lips, who was involved in a conspiracy against Emperor Romanos II in 962. He is also the last known representative of the Lips family.
