Nineteenth-century editors of the Livonian Rhymed Chronicle regarded the now lost Riga MS (= R) as primary, asserting that the only other extant MS for the chronicle, Cpg. 367 (= H), though actually a sister-manuscript, was an ortho-graphically debased copy ofthe former. Obliged because of a large lacuna in R to resort to H (207va, 37–215va, 15) for textual continuity, they proceeded, in line with then established practice for MHG, to normalize these lines, thereby sweeping away various details that would have shed light on the dialectal features of H. On the basis of an examination of such details taken from the manuscript portion in question it is argued that the dialect area in which H was written is East Central German.
