Early Irish Cattle
'Scharff's* 1923 work on early Irish cattle suggests that Bos Longifrons or brachyceros was the original Celtic breed, imported from Asia via continental Europe in the late Stone Age. These animals were supposedly even smaller than the diminutive 'Kerry' breed, which may be their contemporary successors.'
