This chapter re-examines the role of the Irish in the origins of the Old English alphabet. There are many theories about the Old English alphabet's origins. These include those contained in Karl Luick's Historische Grammatik and E. Sievers and K. Brunner's Altenglische Grammatik, which both offered the view that the model for the Old English alphabet was the Latin alphabet. But the first work to cover Old English orthography was Alistair Campbell's Old English Grammar, which rejected the notion that the Latin alphabet which underlay the Old English alphabet was the one taught by the Irish.
