Manchán of Lemanaghan

Saint Manchán mac Silláin (died 664), Manchianus in Latin sources, is the name of an early Irish saint, patron of Liath Mancháin, now Lemanaghan, in County Offaly. He is not to be confused with the scholar Manchán or Manchéne, abbot of Min Droichit (Co. Offaly). There are variant traditions concerning the saint's pedigree, possibly owing to confusion with one of several churchmen named Manchán or Mainchín. The most reliable genealogy makes him a son of Sillán son of Conall, who is said be a descendant of Rudraige Mór of Ulster, and names his mother Mella.

Manchán's church, Liath Mancháin, was located in the kingdom of Delbnae Bethra and its remains now lie approximately two kilometres from Pollagh. The foundation was never able to compete with that of St Ciarán at Clonmacnoise, to the west of Lemanaghan.

Manchán is said to have founded his monastery in c. 645 AD after being provided land by Ciarán. In 644, Diarmuid, high king of Ireland, stopped at Clonmacnoise while on his way to battle Guaire, the king of Connacht. There he asked for the monk's prayer and when he emerged from battle victorious Diarmuid granted St. Ciarán the land of "the island in the bog," now known as Leamonaghan. The only condition was that St. Ciarán was to send one of his monks to Christianize the land, that being St. Manchán. St. Manchán went forward in converting the people and established a monastery.

About 500 meters from the monastery is a small stone house built by Manchán for his mother Mella. The structure is known locally as Kell and the ruins of the house can still be visited today. Legend says that one day the saint was thirsty and the monastery was absent of water. Upon striking a rock a spring well bubbled up, and the area is now known as St. Manahan's well. It's been visited by people from all over the world, commonly on 24 January every year. It is said that many people have been cured of diseases after visiting the well. The saint is also credited with writing a poem in Gaelic, that describes the desire of Ireland's martyrs. He died from the yellow plague in 664. He was known for his generous nature, wisdom and his knowledge of sacred scripture.
