OK, I’m fact-checking one last bit from my Plato book. I’m discussing the famous legend that over the door of Plato’s academy there was an inscription: ‘no non-geometers allowed’. Here’s a page that contains a bit of background if you are unaware of this legend (which is pretty weakly sourced to a commentary on a commentary on Aristotle, I think it is. So who knows.) Anyway, I mention in the text that there are religious overtones, which is most certainly true. But here’s my problem. I read somewhere that over the doors of Greek temples, or at the boundaries of certain holy areas – sites forbidden to those who are unclean, by the terms of Drako’s Law – ‘no unclean persons allowed’. I distinctly recall reading, specifically, that the unclean bit was ‘unjust’; that is, (I presume) ‘adikaios’. So take Plato’s ‘ageometros’, swap it out and plug in ‘adikaios’ and – bob’s your uncle – you’ve got the thing you might read over a temple door. Trouble is: I went back to footnote this bit and it wasn’t where I thought it was. So I’m wondering whether what I have in my book is strictly accurate. Are there surviving inscriptions that are almost like the one Plato is supposed to have put over his door, with only one word different? Or are there reliable reports of the existence of such inscriptions? It’s not a big deal, because the general point about religious overtones stands: the inscription forbids the ‘impure’ from entry, as Drako’s law forbids access to ‘the holy things’ to those who are presently ritually unclean (for whatever reason). But I don’t want my book sullied by the impure inclusion of an epigraphic untruth, Zeus forbid!
