I have been following this thread with great interest. I play(ed) the Scottish pipes, the piob mhor, and have travelled extensively but nowhere have I seen or heard bellow pipes except in Ireland and England. In Scottish Gaelic discussions re bagpipes (or pipe, singular) there is no mention of uillean pipes but a union pipe is called piob na comh sheirm which could be translated as an harmonious pipe. A bellows pipe, piob shionnaich, is called an Irish bagpipe.
A recent posting said 'chanter' was English which, of course, comes from French and Latin before that. There are two Gaelics words for chanter, feadan or whistle, and seannsair which, to my ears, sounds like a Gaelic interpretation of chanter (soft ch sound).
As far as antiquity is concerned there is a mention in Edward Dwelly, quoting from The Expository Times, 1905 "…. The use of the bagpipe can be traced to the most remote antiquity, although it seems, if not comparatively modern in connection with the Highlands, at least to have held a second place in comparison with the harp in the estimation of the bulk of the people, until the last few centuries. The Greek word sumphonfa, which appears as an Aramic loan-word in Daniel, iii, 5, is translated as 'bagpipe' by every competent translator. There is no doubt that the verse relating the arrival of the prodigal son's brother in the New Testament, should be rendered "now his elder son was in the field, and as he came and drew nigh to the house, he heard the bagpipes and dancing."
