Theory that \'Celts\' are a myth

[authun]

In approximately what year was that decision made? :?:

Well it's less of a decision and more a gradual acceptance.

The antiquarians started to use it in the 17th century. I think the first attestation is in 1607, "The Indians were wont to use no bridles, like the Græcians and Celts." in 'The historie of foure-footed beastes'. Then it is picked up by the likes of Milton, "the Ionian gods ... who o'er the Celtic fields roamed the utmost Isles.".

Of course it is still a long way before the term becomes popular. Celtic Football Club was established in 1887, so it had definitely happened by then as presumably there were enough fans around in Scotland who knew what it meant. In Ireland Robert Cane founded the Celtic Union in 1853 which then started to issue a publication named 'The Celt'. Again the term too must have meant something to the membership.

So, I reckon it must have made the change from literary term to popular term sometime between 1667 and 1853, but I don't know the track.
