<< I have been following the postings on Euclid with some interest. One question: Is there a discrepancy between the following two messages? >>
I don't think so. You should look at the full passage in Proclus and see how his confident (but not really very helpful) description of mathematicians breaks down with Euclid, where we get a 'perhaps this, perhaps that' kind of answer. Do not forget that Proclus was a great collector and reader of texts, and would have been more confident if he had found a credible story. The reference in Archimedes is surely a later insertion. Pappus on Euclid is another gentle but vague description which doesn't really say anything. Can anyone quote me the bit from Apollonius, please..

<< ?? Proclus says "He [Euclid] lived in the time of Ptolemy the First, for Archimedes, who lived after the time of the first Ptolemy, mentions Euclid" (apparently meaning only a reference to the _Elements_, the genuineness of which has been questioned). Apollonius and Pappus mention Euclid by name. >>
-----> Avinoam Mann gives us Pappus:
<< From book 7 of Pappus' Collection (Jones ed., v.1, p.116, section 34), about Euclid: "-for he was the fairest of men, and kindly to everyone who was the slightest bit able to augment knowledge, as he should be, and he was not at all belligerent, and though exacting, not boastful..." This says a lot about Euclid the man, even if does not tell us anything about his date or place. Pappus does not give a reference, and these words are in the context of criticising Appolonius (the one who is boastful), but still we cannot ignore them, from somebody who had at his disposal sources no longer available to us. >>
