Rudberg was the first who elaborated upon the idea that Plato's attempt to realize his political ideas in the city of Syracuse could have heavily inspired the Atlantis account. Interpretations Ancient Some ancient writers viewed Atlantis as fictional or metaphorical myth; others believed it to be real. Aristotle believed that Plato, his teacher, had invented the island to teach philosophy. The philosopher Crantor, a student of Plato's student Xenocrates, is cited often as an example of a writer who thought the story to be historical fact. His work, a commentary on Timaeus, is lost, but Proclus, a Neoplatonist of the fifth century AD, reports on it. The passage in question has been represented in the modern literature either as claiming that Crantor visited Egypt, had conversations with priests, and saw hieroglyphs confirming the story, or, as claiming that he learned about them from other visitors to Egypt. Proclus wrote: The next sentence is often translated "Crantor adds, that this is testified by the prophets of the Egyptians, who assert that these particulars [which are narrated by Plato] are written on pillars which are still preserved." But in the original, the sentence starts not with the name Crantor but with the ambiguous He; whether this referred to Crantor or to Plato is the subject of considerable debate. Proponents of both Atlantis as a metaphorical myth and Atlantis as history have argued that the pronoun refers to Crantor. Alan Cameron argues that the pronoun should be interpreted as referring to Plato, and that, when Proclus writes that "we must bear in mind concerning this whole feat of the Athenians, that it is neither a mere myth nor unadorned history, although some take it as history and others as myth", he is treating "Crantor's view as mere personal opinion, nothing more; in fact he first quotes and then dismisses it as representing one of the two unacceptable extremes". Cameron also points out that whether he refers to Plato or to Crantor, the statement does not support conclusions such as Otto Muck's "Crantor came to Sais and saw there in the temple of Neith the column, completely covered with hieroglyphs, on which the history of Atlantis was recorded. Scholars translated it for him, and he testified that their account fully agreed with Plato's account of Atlantis" or J. V. Luce's suggestion that Crantor sent "a special enquiry to Egypt" and that he may simply
