Eligius was born at the 'villa' of Chaptelat (modern Cadillac?), 6 miles west of Limoges, in Aquitaine (now France), into an educated and influential Gallo-Roman family. His father, recognizing unusual talent in his son, sent him to the goldsmith Abbo, master of the mint at Limoges. Later Eligius went to Neustria, the kingdom of the Franks, where he worked under Babo, the royal treasurer, on whose recommendation Clotaire II, king of the Franks, is said to have commissioned him to make a throne of gold adorned with precious stones.
Among other goldsmith's work soon entrusted to Eligius were the bas-reliefs for the tomb of Saint Germain, bishop of Paris. Clotaire took Eligius into the royal household and appointed him master of the mint at Marseilles.
After the death of Clotaire in 629, King Dagobert appointed his father's friend his chief councillor. Eligius' reputation spread rapidly, and ambassadors first sought out Eligius for counsel and to pay their respects to him before going to the king. He made some enemies. His success in inducing the Breton prince, Judicail, to make a pact with Dagobert, at a meeting at the king's villa of Creil (636-37) increased his influence:
Eligius founded several monasteries, and with the king's consent, sent his servants through towns and villages to take down the bodies of criminals who had been executed and give them decent burial. Eligius was a source of edification at court, where he and his friend Dado (Audoenus) lived according to the strict Irish monastic rule that had been introduced into Gaul by Saint Columbanus. Eligius introduced this rule, either entirely or in part, into the monastery of Solignac near Limoges, which he founded in 632 at a villa he had purchased, and also at the convent he founded at Paris, where three hundred virgins were under the guidance of the Abbess Aurea. He also built the basilica of St. Paul, and restored the basilica at Paris that was devoted to St. Martial, the patron bishop-saint of his native Limoges. Eligius also erected several fine tombs in honor of the relics of Saint Martin of Tours, the national saint of the Franks, and Saint Denis, who was chosen patron saint by the king.
On the death of Dagobert (639), Queen Nanthilde took the reins of government, the king Clothar being a child. The tone of the Merovingian court changed. Eligius and Dado left the court.
On the death of Acarius, Bishop of Noyon-Tournai, May 13, 640, Eligius was made his successor, with the unanimnous approbation of clergy and people. 'So the unwilling goldsmith was tonsured and constituted guardian of the towns or municipalities of Vermandois which include the metropolis, Tournai, which was once a royal city, and Noyon and Ghent and Courtrai of Flanders.'
The inhabitants of his new diocese were pagans for the most part. He undertook the conversion of the Flemings, Frisians, Suevi, and the barbarian tribes along the North Sea coast. He made frequent missionary excursions and also founded a great many monasteries and churches. In his own episcopal city of Noyon he built and endowed a nunnery for virgins. After the finding of the body of St. Quentin, Bishop Eligius erected in his honor a church to which was joined a monastery under the Irish rule. He also discovered the bodies of St. Piatus and his martyred companions, and in 654 removed the remains of St Fursey, the celebrated Irish missionary (died 650).
Eligius died December 1, 659 or 660 and was buried at Noyon.
Several writings of Eligius have survived: a sermon in which he combats the pagan practices of his time, a homily on the Last Judgment, and a letter written in 645, in which he begs for the prayers of Bishop Desiderius of Cahors. There are fourteen other homilies attributed to him of doubtful authenticity.
St. Eligius is particularly honored in Flanders, in the province of Antwerp, and at Tournai, Courtrai of Ghent, Bruges, and Douai. During the Middle Ages his relics were the object of special veneration, and were repeatedly divided and transferred to other resting-places, in 881, 1066, 1137, 1255, and 1306. A mass of legend has gathered round the life of St Eloi, who as the patron saint of goldsmiths is still very popular.
He is the patron of goldsmiths, blacksmiths, and all workers in metal. He is generally represented as a bishop, a crosier in his right hand, holding a miniature church of chased gold on the open palm of his left hand. The most familiar image of him is Petrus Christus' painting, Portrait of a betrothed couple and St. Eligius, of 1449.
His life, written by his friend, housemate and companion Dado, Saint Ouen, who was high among the optimates at the Frankish court, is translated on-line at http://www.catholic-forum.com/saints/sto09001.htm
