David Aboav, Euclid’s book on divisions of figures: a conjecture as to its origin. Arch. Hist. Exact Sci. (2008) 62:603–612
It is shown how a diagram on the reverse of a Greek coin of Aegina of the fifth century b.c.e., is simply constructed with the help of Proposition 36 of Euclid’s Book on Divisions [of Figures], and it is conjectured in the absence of contemporary evidence that, since Euclid expressly designated this proposition to be the last in the book, he may have had in mind the diagram, which, some 200 years after its appearance on the coinage, may still have played a significant role in geometry.
As to coins in general it has been said (Poole 1911, p. 869) that “although they
confirm history, [they] rarely correct it, and never very greatly” and that “we gain
from them scarcely any direct historical information, except that certain cities or
princes issued money”. The coin here examined, however, appears to furnish one of
the rare examples of such direct information, and supports the view that Artmann’s
identification of the design on a coin of Aegina as illustrating a proposition of Euclid’s
Elements makes the subject of the present note acceptable for discussion.
