Ptolemy's Catalogue of Stars ¹

Abstract

JUST forty years ago the late Prof. Peters, of Clinton, New York, and Mr. Knobel began independently, and without either of them knowing of the other's work, to investigate the Catalogue of Stars in Ptolemy's Almagest. They soon, however, got into correspondence, and eventually met in Paris in 1887. By that time Peters had collated most of the manuscripts in Continental libraries, and Mr. Knobel then undertook to examine those in England. Peters died in 1890, and in November, 1891, most of his papers and notes bearing on the subject were forwarded to Mr. Knobel, who completed the work, and has now at last suceeded in getting it printed.
