"Constans II (Greek: Κώνστας Β´, Kōnstas II; Latin: Heraclius Constantinus Augustus or Flavius Constantinus Augustus; 7 November 630 – 15 September 668), also called Constantine the Bearded (Κωνσταντῖνος ὁ Πωγωνάτος Kōnstantinos ho Pogonatos), was emperor of the Byzantine Empire from 641 to 668. He was the last emperor to serve as consul, in 642. Constans is a nickname given to the Emperor, who had been baptized Herakleios and reigned officially as Constantine. The nickname established itself in Byzantine texts and has become standard in modern historiography." - (en.wikipedia.org 31.01.2020)
