James Samuel Cole (letter, 8 May) is wrong to claim that Blake's hymn is based on the British Israelite myth. His ideas were the opposite and came from the 18th-century Celtic revival. He believed the patriarchs of the Old Testament were descended from the druids of Britain. Before we pronounce Blake "loony" we should keep an open mind. The great strength of his question "And did those feet ...?" is that nobody knows the answer.
