Constantine, known also by his other names of Cowstan, Chouslan, and Cutchou, was a prince of Cornwall in the sixth century, and was acquainted with Columba and Kentigern. He relinquished his throne and crossed over to Ireland, where he turned monk. At a later date he came to the west of Scotland, and founded a monastery at Golvedir, believed to be Govan, near Glasgow, and, according to Fordun, became its abbot. Kilchouslan Church, on the north side of Campbeltown Bay, Kintyre, was built in his honour. In its graveyard there is, or was till quite lately, a round stone about the size of a grinding stone. In the centre is a hole large enough to let the hand pass through. There is a tradition that if a man and woman eloped, and were able to join hands through this hole before being overtaken by their kinsfolk they were free from further pursuit. In the spring of 1892 an interesting find of old coins was made in the same graveyard. These consisted of groats and half-groats, some of English and some of Scottish coinage, the earliest belonging to the reign of Edward II. of England. According to Martin, the well of St. Cowstan at Garrabost, in Lewis, was believed never to boil any kind of meat, though its water was kept over the fire for a whole day. This well is on a steep slope at the shore. Not far off once stood St. Cowstan's Chapel, but its site is now under tillage. Serf or Servanus, who flourished during the latter half of the seventh century, was connected with the district north of the Firth of Forth, particularly with Culross, and the island named after him in Loch Leven, where he founded a monastery. At Dysart, Serf had a cave, and in it tradition says that he held a discussion with the devil. The name of Dysart indeed, comes from this desertum or retreat. Serf had a cell at Dunning, in Strathearn, where he died in the odour of sanctity. He had also some link with the parish of Monzievaird, where the church was dedicated to him, and where a small loch still goes by the name of St. Serf's Water. There is a well sacred to him at Alva. St. Shear's Well, at Dumbarton, retains his name in an altered form. Early last century this spring was put to a practical purpose, as arrangements were then made to lead its water across the Leven by pipes to supply the burgh. CHAPTER IV. MORE SAINTS AND SPRINGS.
