Ah it's just occurred to me that you probably searched for 'diongbhálta' on that site

Sorry the above should read "early 19th century book".

It's a book from 1822. The original is very hard to come by, but the 1910 reprint shows up now and then in antiquarian fairs in Ireland. It's a translation of De Imitatione Christi by Thomas à Kempis. My copy is the 1910 one. The RIA has a 1822 original. The spellings are not the exact same.

It's quite interesting to compare it with Peadar Ua Laoghaire's later translation. Quite a few differences. Not so much in morphology, but in the syntax and style.

I read somewhere that Ua Laoghaire thought Searc-leanmhain Chríost a poor translation into stilted Irish and that is why he decided to do his own translation, Aithris ar Chríost. I don't know where I read it - it my have been in Sr Mary Vincent's An tAthair Peadar Ó Laoghaire agus a Shaothar. I got a copy of Searcleanmhain Chríost for $20 from abebooks. It's in a box somewhere. I think that must be the 1910 edition too.

Have you any advice for coming across these books or finding these fairs? I've been to fairs where people are selling antiques but there are never any old Irish books.
I've sometimes seen things like this in antique bookshops in Dublin but usually selling for wild money.

You can look on abebooks, eg https://www.abebooks.com/servlet/BookDe ... ortby%3D17

ABE books, or book fairs out in the country. Particularly West of the Shannon. Older book shops often have a high density of Irish books. Most are on ABE but some aren't like Gadaí Dubh in Macroom or Michael Slavin's bookshop at Tara, both of which have many seanchló books.

Personally I would say it's nowhere near as good as Ua Laoghaire's translation. There's a lot of aping of the classical style which is always stilted.

Any other big ones, or fairs you'd recommend? I'm hunting in particular after two books - Sgéalaidhe Leitir Mealláin and the original edition of Cruithneacht agus Ceannabháin, as the school versions all seem to have a story missing. Haven't had any luck on Abebooks yet with it, or utilising Bookfinder/Find More Books. Thinking of going off on a tour of used bookshops across the country to hunt them down if possible, so any recommendations would be great.

Once I get those two I think I'll have pretty much every 20th century pre-Caighdeán book by Conamara authors in the first edition, barring only the works of Pádhraic Óg Ó Conaire, which are a lot easier to find I've found.

You could find them in the National Library or maybe NUI Galway and get the missing story that way?

Oh, I've already found it and read it, but I want a physical copy of it. I actually found one recently and will purchase it tomorrow. The physical copy is for my own Conamara-oriented library. Slowly working its way towards pre-Caighdeán Conamara filled completion, then I'll venture out to Mayo.
