I'm working on carbon isotope shifts in late prehistoric skeletal material (late Neolithic through to Iron Age) from both Britain & the Continent. Millet, as a C4 plant, is a suspect for some of what I'm seeing on the western European mainland & I've seen literature which supports the presence of Panicum miliaceum in increasing amounts over the period I'm looking at. But I've never seen any reference to its presence in the UK. I'm increasingly wondering why it isn't there - surely if it's around in small quantities in Germany, Austria, Switzerland & Denmark (for instance) as early as the Neolithic and increasing in quantities through to the Iron Age, it would have got to Britain somehow, at least by the Iron Age, even if only on a bird & a breeze? I'm not necessarily so concerned about the idea of it as a domesticated crop, only as a presence, perhaps just as a 'weed' that could get included in the diet of domesticated herbivores. Does anyone have any information/literature references/comments? Mandy Jay
