Editorial Principles

The Greek text. The text is based on a transcription made from photographs of the Vaticanus, subsequently collated with Hultsch’s text, Commandino’s translation, and the partial editions. Some passages, where moisture had long ago made the manuscript difficult to read, were collated again with the Vaticanus itself; personal inspection revealed that much of the text in these places could be read from the impression of the scribe’s pen. In a small number of passages the original text is practically illegible; these have been enclosed in half-brackets (“⌈”, “⌉”) in this edition.
