Saint Adrian of May (sometimes given as "Magridin") (d. 875) was a martyr-saint of ancient Scotland, whose cult became popular in the 14th century. He is commemorated on 3 December. He may have been a bishop of Saint Andrews. Life and martyrdom Little is known of the life of this Scottish saint and martyr. He is held by some to have been an Irish monk and bishop, with the Gaelic name of Ethernan, who, though he might have been the Bishop of St. Andrews, was drawn to remote locations and had built a series of monasteries and hermitages on the Isle of May (which is out to sea in the Firth of Forth) and along the coast of Fife. Later he withdrew from his see of St. Andrews due to the invading Danes and took refuge on the island. What is known is that about A.D. 875, marauding Vikings invaded the island of May. They then slaughtered the entire population of the monastery, traditionally numbered at six thousand six hundred. The island was then abandoned for centuries. In 1145, King David I of Scotland gave the island to Reading Abbey in Berkshire, England, at which point, the island again became a religious centre. The English monks started the erection of a small monastery dedicated to St. Mary the Virgin, with a shrine to St. Ethernan. Early building was hampered due to raiding parties of Scandinavians who had settled in Orkney. The privations and isolation of the location finally led the monks to transfer the island in some manner to the Bishop of St. Andrews in A.D. 1288. Shortly thereafter, in 1296, war broke out between the Kingdoms of Scotland and England over territorial claims along the border between the two realms. This was paralleled in a legal fight between the abbey and the bishop over who actually owned the island. Initially, the abbey was confirmed as the lawful owner. This, however, was overturned in 1313 and the island was declared a part of the diocese. In consequence of this, English forces attacked the island and destroyed the monastery. After the conclusion of hostilities, the island became an important symbol of national pride, and pilgrimages to May became a common feature of religious life for the Scottish people. Royal pilgrims According to the chronicle of Mathieu d'Escouchy, Mary of Guelders visited the Isle of May and the shrine of St Adrian
