Input: Question: How much did the revenues of Crossraguel Abbey amount to when George Buchanan was given them by the queen? Passage:In 1560 or 1561 Buchanan returned to Scotland, and by April 1562 was installed as tutor to the young Mary, Queen of Scots, who read Livy with him daily. Although he had remained Catholic throughout his support of the new learning and his strident criticism of the vices of the clergy, he now openly joined the Protestants Reformed Church and in 1566 was appointed principal of St Leonard's College, St Andrews, by the Earl of Moray. Two years before, he had received from the queen the gift of the revenues of Crossraguel Abbey. Though a layman, he was made Moderator of the General Assembly of the Church of Scotland in 1567. He had sat in the assemblies from 1563. He was the last lay person to be elected Moderator until Alison Elliot in 2004, the first female Moderator.
