Over the past few weeks since I wrote a post about the account by Tacitus of a potential Roman invasion of Ireland led by Agricola I’ve been thinking about a couple of open questions and digging around in various commentaries to try to shed light on them. Both of these pertain to the first section of Part 24 of the account, which is in the fifth year of his Agricola’s campaigning
Quinto expeditionum anno nave prima transgressus1 ignotas ad id tempus gentis crebris simul ac prosperis proeliis domuit; eamque partem2 Britanniae quae Hiberniam aspicit copiis instruxit...
The first question relates to transgessus meaning “crossed”. Where did he cross? I remembered all the way back to school days reading some of this, and found the following in Vol. 1 of the Latin textbook we used back then (Wilding’s Latin Course for Schools). On page 68 of that tome we find the following as part of an exercise to translate from Latin to English:
Agricola copias Clanoventae, ubi ora Britanniae ad Hiberniam spectat...
Clanoventae is a Roman name for the town of Ravenglass, near the Cumbrian coast. At the time I took this to be a direct quote from Tacitus, but it isn’t. Obviously Wilding made that bit up! There is evidence of substantial Roman activity at Ravenglass, but none that this was the place he placed the troops intended for a possible invasion of Ireland. Moreover, the actual quote from Tacitus makes it clear that he “crossed” with ships, but that doesn’t seem right when you look at the location (marked with the red thingy):
It’s quite a long way to “cross” from there to modern-day Scotland, and in any case what you would see from there is first and foremost the Isle of Man. From there he could definitely see both Britain and Ireland, but as far as I know there’s little or non direct evidence of Roman activity there, though the Romans did know it through trading interactions. They called it Insula Manavia. Tacitus does not use place names very often – there are only half-a-dozen – in the entire book about Agricola but it seems to me he would not have confused it with Hibernia.
Putting my school textbook away and turning to other commentaries, I didn’t find any real consensus but the best bet is that what Agricola crossed was the Solway Firth, and where he crossed from could well have been Maryport, also a well-known Roman military site (called Alauna). There is no direct evidence for that either, though, and the earliest directly dated evidence of significant activity there is much later, around 122AD. Agricola’s incursion to Scotland was around 81 AD.
If Agricola did cross the Solway Firth he and his army would have landed in what is now Dumfries and Galloway. Most commentaries now believe that the place from which he could see Ireland would be the Rhinns of Galloway, the hammer-shaped peninsula to the West of Stranraer. Now that isn’t the part of Scotland closest to Ireland – that would be the Mull of Kintyre, much further North – but it is pretty close, and it certainly does face across the Irish Sea with nothing in the way.
There is also plenty of evidence of Roman activity near Stranraer, including a settlement and fort in a place known to them as Rerigonium. There are also traces of a Roman road. That is important because, to the Romans, roads were primarily military structures, meant to facilitate the movement of troops and supplies quickly. Had the Romans ever invaded Ireland they would have built an extensive network of roads, as they did in England.
It seems to me that Rerigonium would have been a good choice of place to launch the putative invasion. Loch Ryan would have provided a natural harbour for the ships that would take troops the short distance to Ireland and it’s not difficult to imagine a Roman legion embarking there.
P.S. When I was a lad there were regular ferries from Stranraer to Belfast and back, but now they operate to and from Cairnryan, about 6 miles further up Loch Ryan.
