According to the vita or ‘Life’ of Saint Columba written by Adomnán at the end of the seventh century, the monastery on Iona had a number of satellites on various islands and coastlands around Argyll. One of these was on an island called Hinba and seems to have been the chief daughter-house of Iona. Adomnán tells us that it was founded by Columba himself and comprised not only a monastery but also a separate hermitage. Frustratingly, the precise location of Hinba is not made clear, so we are left to wonder which of the numerous Hebridean islands it was.
People have been suggesting possible identifications for Hinba for a long time, ever since modern historians first began to study Adomnán’s Vita Columbae. The obvious starting-point is to rule out those islands which are clearly identifiable in Adomnán’s narrative, such as Skye, Islay, Tiree, Eigg, Mull and of course Iona itself. None of these was Hinba, so the search is immediately narrowed. It also seems clear that Hinba lay at no great distance from Iona, for Columba was able to visit the satellite monastery quite easily and frequently. His uncle Ernán, who served as prior on Hinba, was able to undertake the sea-voyage to Iona when very elderly and in poor health.
The hermitage on Hinba was situated near what Adomnán calls Muirbulc Mar, ‘Great Sea-Bay’. As with some other places in Vita Columbae he gives the name entirely in Gaelic – his own native language – rather than rendering it into a Latinised form. Muirbulc Mar must have been a prominent feature, so any island without a large bay can effectively be ruled out in our search for Hinba. For example, the small island of Eileach an Naoimh, ‘Rocky isle of the Saints’, in the Garvelloch archipelago has been suggested as a possible candidate for Hinba but it doesn’t have a prominent sea-bay. Also, Hinba is a Gaelic name, so it is very unlikely that it would be given an additional or alternative Gaelic one. Indeed, it is far more likely that it today bears a name of Norse origin, as do many of the Hebridean islands.
The eminent place-name scholar William Watson proposed that Hinba derives from inbe, a Gaelic word meaning ‘incision’. In this context, the ‘incision’ would presumably be the great sea-bay of Muirbulc Mar. If Watson’s derivation is correct, the bay must have appeared to slice through the island, as if the sea had bitten a big chunk out of the coastline.
Only two candidates seem to tick all the boxes: Jura, which has a large sea-bay called Loch Tarbert; and the single island which is formed by Colonsay and Oronsay when the sea-bay between them is at low tide. Jura and Colonsay/Oronsay have Viking names, and we don’t know what they were called in Adomnán’s time. Jura has an early church dedicated to Columba; Oronsay has a medieval priory with a Columba dedication and an old tradition of having been founded by the saint. In favour of Colonsay and Oronsay is the observation that they are closer to Iona.
The upshot is that the puzzle of Hinba remains unsolved. This mysterious island, so important in the early history of the Columban familia or network of monasteries, seems to float beyond our reach. My own view is that it is now the single island formed by Colonsay and Oronsay at low tide, and that Oronsay Priory stands on the site of Columba’s monastery.

References to Hinba in Adomnán’s Vita Columbae occur at: Book 1, chapters 21 & 45; Book 2, chapter 24; Book 3, chapters 5, 17, 18 & 23. The Latin edition I use is the one edited by Alan and Marjorie Anderson in 1961 (revised in 1991). For an English version I use the Andersons’ translation and the one by Richard Sharpe for Penguin Classics (1995).
I discuss Hinba on pp.109-11 of my book on Saint Columba.
A useful summary of the various Hinba theories can be found on pp.91-102 of Alan Macquarrie’s The Saints of Scotland (Edinburgh, 1997).
Hinba is the island where Saint Columba narrowly escaped being murdered. The story is told in my blogpost Columba and the Pirates.
