Ptolemy's Almagest
"G.J. Toomer's new English edition of Ptolemy's classic treatise is more than just a fresh translation.... What Toomer has produced is the best edition in any language, one that will remain the standard preferred text for years to come."--Nature"On the whole the accuracy and faithfulness to the original, including the small but important matter of a scrupulous adherence to Ptolemy's own mathematical notations, are exemplary."--G.E.R.
