Thus we have here Pictish sea-robbers attacking the monastery in Tiree; and Adamnan tells us of a noted pirate of the royal tribe of Gabhran, and therefore a Scot, called Johan, son of Conall, whose seat appears to have been the rude fort which gave the name of Dunchonell to one of the Garvelochs, and whom we find plundering in the district of Ardnamurchan.[255] He also tells us of a robber, Erc, the Druid’s son, who resided in Colonsay, and who plunders in the island of Mull. Of Columban monasteries in Tiree, Adamnan mentions two. One he calls ‘Campus Lunge,’ or the plain of Lunge. It was situated near the shore over-against Iona, and had a _portus_, or harbour, which is probably the little creek or bay still known as Portnaluing; and the site of the monastery has been identified with that of Soroby on the south-east side of the island, where a large churchyard with some old tombstones and an ancient cross are the only remains of an ecclesiastical establishment. The monastery is frequently mentioned by Adamnan. It seems to have been founded at an early period, and was under the charge of Baithen, afterwards the successor of Columba in the abbacy of Iona.[256] The second is termed by Adamnan Artchain, and said to have been founded by Findchan, one of Columba’s monks, whose name also appears in Kilfinichen in the island of Mull.[257] The island, too, which he calls Hinba, is repeatedly mentioned by Adamnan, and seems also to have been an early foundation. He tells us that at one time Columba sent Ernan, his uncle, an aged priest, to preside over the monastery he had founded many years before in that island;[258] and it seems to have been especially connected with the penitential discipline of the order, and a place of retirement for those who wished to lead a more solitary life. Thus, we find Columba on one occasion visiting Hinba, and ordering that the penitents should enjoy some indulgence in respect of food, which one of the penitents in that place, a certain Neman, refused to accept.[259] Again, one of the brethren, Virgnous, after having lived for some time in the monastery of Iona, resolved to spend the rest of his life in Hinba, and led the life of an anchorite for twelve years in the hermitage of Muirbulcmar.[260] The church and the house occupied by Columba are mentioned by Adamnan, and it is not impossible that the hermitage here referred to yet exists in one of the two beehive cells, which is still entire.[261] Here, too, he tells us that four holy founders of monasteries came from Ireland to visit Columba, whom they found in Hinba. These were Comgall of Bangor and Cainnech of Achaboe, the two who had accompanied him in his first visit to King Brude, Brendan of Clonfert, and that Cormac for whom, when on a voyage in search of a solitary island in which to found a hermitage, he asked King Brude to secure the protection of the ruler of the Orkneys. This meeting must have taken place before the year 577, when Brendan died. They are
