St Machor was one of the disciples of St Columba, the famous apostle of the Northern Picts and founder of the celebrated monastery of Iona. According to the ‘Aberdeen Breviary,’ “sanctum virum gignit Hibernia, educavit illum Albania, cujus corpus in reverentia Turonensis tenet ecclesia.” He was the son of Syaconus or Fiachna, an Irish kingling, and Synchena or Finchœmia, his wife, both of whom appear to have been Christians. At baptism, a rite which, according to the ‘Aberdeen Breviary’ was performed for him by St Colman, he received the name of Mocumma. St Colman was also his first instructor. Proofs and indications of his sanctity were vouchsafed while he was yet a child. Angels visited him, and hovered around his home and cradle; at the touch of his body his dead brother was restored to life, and twice he was miraculously delivered from death by drowning and by fire. Sent by his father to be instructed by St Columba, he soon became a most devoted scholar and disciple of that saint. When Columba was about to leave Ireland for Scotland, Mocumma refused to be left behind, and resolved to leave his country and home and friends in order to be with him. Overjoyed with the zeal and attachment of his disciple, Columba changed his name from Mocumma to Machor or Machar. When they landed on the island of Iona, Machor was carried ashore by a certain Melluma. After the cells had been built and the community thoroughly established in their new home, St Columba sent Machor to evangelise the island of Mull. There he preached the Gospel over the whole land and healed seven lepers. Returning to Iona after the completion of his work in Mull, he devoted himself to study and to the copying of the Scriptures, one of the chief works in which the disciples of Columba were engaged. One day as he wrote the light failed him, but blowing on “his fyngre-end,” a bright light immediately issued from it, and lighted him until his task was done. The fame which this and other miracles brought him, soon caused great companies to gather around him, offering him gifts, all of which, however, he refused to accept. On the other hand, his fellow-disciples were moved with jealousy, and attempted to poison him. Alarmed for the personal safety of his favourite disciple, Columba advised him to withdraw from the island, and preach the Gospel elsewhere. Machor accepted his advice, and Columba gave him seven, or, according to another account, twelve companions, a bishop’s staff, a girdle, two coats, and a number of books, and then sent him away in a “galay” or boat, but not before his fellow-disciples who had made the attempt on his life had been reconciled to him. Machor landed in the north of Scotland, where a Christian man named Farcare resided, who received him with great joy, and allowed him to choose any portion of his land on which to build his cell. After much searching, he selected a piece in the shape of a bishop’s staff, which answered to the description Columba had given him of the place where he was to fix his dwelling. Here he caused a “costly kirk” to be built, and miraculously provided a supply of water for the thirsty workmen. Here also he collected round him a great company of disciples. St Devenick came to visit him, and the two agreed that St Devenick should preach the Gospel in Caithness, and that St Machor should confine himself to the Picts. St Machor threw himself into his work with great earnestness, and converted a large number of Picts and wrought numerous miracles. He changed a bear, which was destroying the harvest, into a stone; he overcame a heathen sorcerer named Dinon or Dron, and then converted and baptised him; he gave sight to a man that was born blind, and raised Synchenus, who belonged to the kindred of St Columba, from death to life; two young Irishmen, attracted by his fame, having mocked him, came by a violent end; having ploughed a large field which was lean and dry, and seed failing him with which to sow it, he sent to borrow some from St Teman, who sent instead a sack of sand — but sowing this, it sprang up and bore an abundant harvest; a bone which had stuck in the throat of a man Avho had despised him, he safely extracted, and received in return a piece of land on which to build a church. One day St Teman came to visit him; he entertained him, and the two held a long conversation on heavenly things, Machor becoming the instructor of his visitor, and causing him to marvel at his wisdom. As he lay on the point of death St Devenick besought his disciples to carry his dead body to one of the churches of St Machor for burial, and, instructed by a vision, the latter went to meet the funeral procession. He met it near the Hill of Croscan, and accompanied it to Banchory-Devenick, where the saint was buried, and a church erected over his tomb. When St Columba proceeded on his pilgrimage to Rome, Machor accompanied him. Both were graciously received by Gregory the Great, who appointed Machor bishop of the Picts, or, according to another account, bishop of Tours, changed his name to Morice or Mauritius, and instructed him in the duties of a bishop. On their return journey Columba and Machor visited Tours. The clergy of that city were then searching for the body of St Martin. On applying to St Columba for assistance, he promised to help them on the condition that he should have whatever he found with the body. His search was successful and along with the body he found a missal or “a book of the Gospel,” which he treasured all the remainder of his life as a precious relic. St Columba then took his way home, but left Machor, much against his will, though at the earnest request of the people of Tours. For the space of three years and a half St Machor occupied the Chair of St Martin, by whom he was visited. His deathbed was visited by St Martin from heaven, by St Columba from Iona, and by the Son of God, and ever and around it were the company of the Apostles, and a great host of heavenly beings.
The old Latin life from which the six lections in the ‘Aberdeen Breviary,’ November 12, and the passages in Colgan’s ‘Trias Thaumaturga,’ 318, 514, appear to have been taken, is now lost. Besides these, cf. Reeves, ‘Life of St Columba by Adamnan’; Forbes, ‘Kal. of Scottish Saints,’ sub Mauritius; J. Smith, ‘Life of St Columba.’ The narrative given in the Legend is the longest and fullest and most important known. Machor is mentioned in the Arbuthnott and Aberdeen Calendars, and in Adam King’s, where he is said to have lived during the reign of ‘King Soluathius in Scotland.” The ‘Menologium Scotium’ refers to him, January 15 and November 12. and in the Calendar of David Camerarius he occurs under November 13.
His day is November 12.
