The mother of Constantine the Great , born about the middle of the third century, possibly in Drepanum (later known as Helenopolis ) on the Nicomedian Gulf; died about 330. She was of humble parentage; St. Ambrose, in his "Oratio de obitu Theodosii", referred to her as a stabularia , or inn-keeper. Nevertheless, she became the lawful wife of Constantius Chlorus. Her first and only son, Constantine, was born in Naissus in Upper Moesia, in the year 274. The statement made by English chroniclers of the Middle Ages, according to which Helena was supposed to have been the daughter of a British prince, is entirely without historical foundation. It may arise from the misinterpretation of a term used in the fourth chapter of the panegyric on Constantine's marriage with Fausta, that Constantine, oriendo (i.e., "by his beginnings," "from the outset") had honoured Britain, which was taken as an allusion to his birth, whereas the reference was really to the beginning of his reign.

In the year 292 Constantius, having become co-Regent of the West, gave himself up to considerations of a political nature and forsook Helena in order to marry Theodora, the step-daughter of Emperor Maximinianus Herculius, his patron, and well-wisher. But her son remained faithful and loyal to her. On the death of Constantius Chlorus, in 308, Constantine, who succeeded him, summoned his mother to the imperial court, conferred on her the title of Augusta, ordered that all honour should be paid her as the mother of the sovereign, and had coins struck bearing her effigy. Her son's influence caused her to embrace Christianity after his victory over Maxentius. This is directly attested by Eusebius (Vita Constantini, III, xlvii): "She (his mother) became under his (Constantine's) influence such a devout servant of God, that one might believe her to have been from her very childhood a disciple of the Redeemer of mankind ". It is also clear from the declaration of the contemporary historian of the Church that Helena, from the time of her conversion had an earnestly Christian life and by her influence and liberality favoured the wider spread of Christianity. Tradition links her name with the building of Christian churches in the cities of the West, where the imperial court resided, notably at Rome and Trier, and there is no reason for rejecting this tradition, for we know positively through Eusebius that Helena erected churches on the hallowed spots of Palestine. Despite her advanced age she undertook a journey to Palestine when Constantine, through his victory over Licinius, had become sole master of the Roman Empire, subsequently, therefore, to the year 324. It was in Palestine, as we learn from Eusebius (loc. cit., xlii), that she had resolved to bring to God, the King of kings, the homage and tribute of her devotion. She lavished on that land her bounties and good deeds, she "explored it with remarkable discernment", and "visited it with the care and solicitude of the emperor himself". Then, when she "had shown due veneration to the footsteps of the Saviour", she had two churches erected for the worship of God : one was raised in Bethlehem near the Grotto of the Nativity, the other on the Mount of the Ascension, near Jerusalem. She also embellished the sacred grotto with rich ornaments. This sojourn in Jerusalem proved the starting-point of the legend first recorded by Rufinus as to the discovery of the Cross of Christ.

Her princely munificence was such that, according to Eusebius, she assisted not only individuals but entire communities. The poor and destitute were the special objects of her charity. She visited the churches everywhere with pious zeal and made them rich donations. It was thus that, in fulfilment of the Saviour's precept, she brought forth abundant fruit in word and deed. If Helena conducted herself in this manner while in the Holy Land, which is indeed testified to by Eusebius, Bishop of Caesarea in Palestine, we should not doubt that she manifested the same piety and benevolence in those other cities of the empire in which she resided after her conversion. Her memory in Rome is chiefly identified with the church of S. Croce in Gerusalemme. On the present location of this church formerly stood the Palatium Sessorianum , and near by were the Thermae Helenianae , which baths derived their name from the empress. Here two inscriptions were found composed in honour of Helena. The Sessorium , which was near the site of the Lateran, probably served as Helena's residence when she stayed in Rome ; so that it is quite possible for a Christian basilica to have been erected on this spot by Constantine, at her suggestion and in honour of the true Cross.

Helena was still living in the year 326, when Constantine ordered the execution of his son Crispus. When, according to Socrates' account (Hist. eccl., I, xvii), the emperor in 327 improved Drepanum, his mother's native town, and decreed that it should be called Helenopolis, it is probable that the latter returned from Palestine to her son who was then residing in the Orient. Constantine was with her when she died, at the advanced age of eighty years or thereabouts ( Eusebius, "Vita Const.", III, xlvi). This must have been about the year 330, for the last coins which are known to have been stamped with her name bore this date. Her body was brought to Constantinople and laid to rest in the imperial vault of the church of the Apostles. It is presumed that her remains were transferred in 849 to the Abbey of Hautvillers, in the French Archdiocese of Reims, as recorded by the monk Altmann in his "Translatio". She was revered as a saint, and the veneration spread, early in the ninth century, even to Western countries. Her feast falls on 18 August.

No one who is interested in human history, past and present, can ignore the Catholic Church, either as an institution which has been the central figure in the civilized world for nearly two thousand years, decisively affecting its destinies, religious, literary, scientific, social and political, or as an existing power whose influence and activity extend to every part of the globe. In the past century the Church has grown both extensively and intensively among English-speaking peoples. Their living interests demand that they should have the means of informing themselves about this vast institution, which, whether they are Catholics or not, affects their fortunes and their destiny.
