Scots vs Irish
If you thought the Picts were confusing (see earlier post), their nomenclature is a model of clarity compared with the Scots and the Irish. Example:
There's a Scottish monastery (Schottenkloster) in Vienna, founded in the 12th century. Why is it so-called? Because it was founded by Irish monks.
(Does this sort of apparent illogic explain the popularity of the "Irish joke"? Discuss.)
This delightful fact was mentioned in passing on Radio 4's Food Programme on Sunday 16 Dec. They were doing a feature on Vienna's Christmas markets, if you want to listen again.
