COLBURN, Zerah (1804 -39). ZerAh Colburn. London: Henry Meyer, 1813. Full-length stipple-engraved portrait of the lightning calculator and child prodigy, ?From a drawing by T. Hull Esq. in the possession of F Baily, Esq.? holding a battledore and shuttlecock. 15 x 13?. Margins scuffed and skinned, old mounting tape, else good. This image was used as the frontispiece to Colburn?s Memoir in a much smaller format. Rare; the first example we have encountered. The caption below the likeness well summarizes Colburn?s miraculous nature: ?A child just eight years of age endowed with the remarkable faculty of solving a great variety of arithmetical questions by the operation of his mind.? Below the caption is the printed statement: ?A printed account of the child is delivered with the portrait.? This was likely a sheet of similar size, giving further details on Colburn?s remarkable abilities. His life story, written ?by himself? was published in America twenty years later.
