We have in a previous chapter referred to Ciaran's sojourn in Aran with St. Enda. On his departure from the blessed isles Ciaran told the venerable Enda that he saw in a vision a large fruitful tree planted in the midst of Erin, and its boughs sheltered all the land. Its fair fruit was borne over land and sea, and all the birds of the air came and eat thereof. "That tree is thyself," said Enda; "all Erin shall be filled with thy name, and sheltered by the grace that will be in thee, and many men from all parts will be fed by thy prayers and thy fastings. Go, then, in God's name, and found thy Church on the Shannon's banks in the centre of the island." After leaving Aran, Ciaran paid a short visit to St. Senan of Scattery Island, in the Lower Shannon, and was much edified by the example and conversation of that holy man. He then went north in obedience to the word of Enda and at first founded a church at a place called Isell Ciaran, where he remained only a short time. He then founded another oratory on Inis Ainghin, now called Hare Island, in Lough Ree, a beautifully wooded islet about two miles north of Athlone, where a ruined church may still be seen that was built on the site of Ciaran's more ancient oratory. It was an admirable site for a monastery; far enough from the shore for security, but near enough for convenience, and situated just at the point where the wide and beautiful lake contracts its waters into the stately stream that flows beneath the historic arches of the bridge at Athlone.
