R. S. O. Tomlin has recently provided an excellent publication of an amulet found in the City of London in 1989. It is a long, narrow strip cut from a sheet of pewter, with 30 lines of Greek text, and the bearer was a certain Demetri(o)s. By a curious coincidence, two of the Greek inscriptions of Britain also involve a Demetrios, though a different one. They are inscribed on two bronze plates found in York about 1840. One reads , the other , and the bearer is presumably identical with a grammaticus from Tarsus of the same name, described as having come from Britain to Delphi in one of Plutarch's dialogues. This note mainly treats the second of two hexameter oracles incorporated in the text of the London amulet, but I begin by discussing the text as a whole.
