Eusebius of Caesarea, Life of Constantine 4.61

Γίγνεται δ’ αὐτῷ πρώτη τις ἀνωμαλία τοῦ σώματος, εἴτ’ οὖν κάκωσις ἐπὶ ταύτην συμβαίνει, κἄπειτα τῆς αὐτοῦ πόλεως ἐπὶ λουτρὰ θερμῶν ὑδάτων πρόεισιν, ἔνθεν τε τῆς αὐτοῦ μητρὸς ἐπὶ τὴν ἐπώνυμον ἀφικνεῖται πόλιν. κἀνταῦθα τῷ τῶν μαρτύρων εὐκτηρίῳ ἐνδιατρίψας οἴκῳ ἱκετηρίους εὐχάς τε καὶ λιτανείας ἀνέπεμπε τῷ θεῷ. ἐπειδὴ δ’ εἰς ἔννοιαν ἥκει τῆς τοῦ βίου τελευτῆς, καθάρσεως εἶναι τοῦτον καιρὸν τῶν πώποτε αὐτῷ πεπλημμελημένων διενοεῖτο, ὅσα οἷα θνητῷ διαμαρτεῖν ἐπῆλθε ταῦτ’ ἀπορρύψασθαι τῆς ψυχῆς λόγων ἀπορρήτων δυνάμει σωτηρίῳ τε λουτρῷ πιστεύσας. τοῦτό τοι διανοηθείς, γονυκλινὴς ἐπ’ ἐδάφους ἱκέτης ἐγίγνετο τοῦ θεοῦ, ἐν αὐτῷ τῷ μαρτυρίῳ ἐξομολογούμενος, ἔνθα δὴ καὶ πρῶτον τῶν διὰ χειροθεσίας εὐχῶν ἠξιοῦτο.

'First a bodily indisposition came upon him, then illness supervened, and thereupon he went out to the hot water baths of his city, and from there to the city named after his mother. There he spent his time at the chapel (εὐκτήριον/euktērion) of the martyrs, and offered up supplicatory prayers and petitions to God. But when he became aware that his life was ending, he perceived that this was the time to purify himself from the offences which he had at any time committed, trusting that whatever sins it had been his lot as mortal to commit, he could wash them from his soul by the power of the secret words and the saving bath. Having perceived this, he knelt on the floor and made himself a suppliant to God, making confession in the martyrion itself, where also he was first accorded the prayers that go with laying-on of hands.'

Eusebius wrote the Life of Constantine in the two years between the death of his hero (337) and his own (339), without finishing the work. The author portrays the first Christian emperor as an ideal ruler, sent from God, who ended the persecution of Christians and led the Roman Empire to the true faith. Based on imperial documents, legal texts and personal communication, the Life of Constantine, though clearly biased, is one of our fundamental sources of information on the reign of Constantine.


The passage quoted here is one of our basic sources about the death of the emperor Constantine in May 337. Although rather indefinite in its details, it is the first extant reference to a martyr shrine in Helenopolis, a port-town of the Bithynian coast. According to Eusebius, after celebrating Easter in 337, and while preparing to campaign against Persia, Constantine fell ill and sought relief at the thermal baths ‘of his city’. By this, the author almost certainly refers to Pythia (today’s Termal, near Yalova), which was the main spa resort in the vicinity of Constantinople, remaining popular into our days. It was located in the mountains of coastal Bithynia within an area between Nicaea and Nicomedia, which, until the foundation of Constantinople, belonged to the city of Byzantium. Constantine turned this territory into a separate city which he named Helenopolis, after his mother. This explains why the ill emperor went to Helenopolis after taking the waters. Helenopolis, located on cape Drepanon (mod. Hersek), was a port-town probably built in order to facilitate the communication between Constantinople and Anatolia (see Mango 1994). The text of Eusebius reports that Constantine prayed at the local martyrium and received there the first rites of Christian initiation 'by the laying of hands' – very probably, he was proclaimed a catechumen. The text is an important testimony to the existence of a martyrium in Helenopolis already under Constantine. According to tradition, Cape Drepanon/Helenopolis was the burial site of the martyr Loukianos of Antioch, but it is not explicit if it was at his shrine that Constantine prayed. This lack of detail, however, may be ascribed to the unfamiliarity of Eusebius with the area, which is otherwise also evident in his geographically vague account.
