The most famous work in which St. Finan was directly concerned was the foundation by Oswy of the Monastery of Streaneshalch on the precipitous headland afterwards known as Whitby. This was to become in later years, under the rule of the first abbess, Hilda, a school of saints and a centre of learning for the whole territory in which it stood, and the admiration of after ages for its fervour and strictness of discipline. St. Finan died after an episcopate of ten years, and was laid to rest beside the remains of St. Aidan in the cathedral he had built at Lindisfarne. His feast was restored to Scot land by Leo XIII. in 1898. 18--St. Colman, Bishop, A.D. 676. On the death of St. Finan, another monk of Iona was chosen to succeed him in the see of {26} Lindisfarne. This was Colman, who, like Finan, was of Irish nationality. At the time a fierce controversy was raging in Britain as to the correct calculation of Easter. The Roman system of computation had undergone various changes until it was finally fixed towards the end of the sixth century. It was adopted gradually throughout the Church, but Britain and Ireland still retained their ancient method. In consequence of this it sometimes happened that when the Celtic Church was keeping Easter, the followers of the Roman computation were still observing Lent. This was the case in the Court of Oswy, King of Bernicia, who followed the Celtic rite, while his Queen Eanfleada and her chaplains, who had been accustomed to the Roman style, kept the festival in accordance with it. To bring about uniformity a synod was held at Whitby to give the advocates of either system an opportunity of stating their views. St. Wilfrid, the great upholder of Roman customs, brought such weighty arguments for his side that the majority of those present were persuaded to accept the Roman computation. {27} St. Colman, however, since the Holy See had not definitely settled the matter, could not bring himself to give up the traditional computation which his dear master, St. Columba, had held to. He, therefore, resigned his see, after ruling it for three years only, and with such of the Lindisfarne monks as held the same views retired to Iona. On his way thither he seems to have founded the church of Fearn in Forfarshire, which he dedicated to St. Aidan, placing there some of the saint's relics brought with him from Lindisfarne. He also founded a church in honour of the same saint at Tarbert in Easter-Ross. This, however, was afterwards called by his own name.
