| Dec 25, 2014 at 20:17 | comment | added | Joel David Hamkins | Doesn't the essential idea---that symmetries have to do with invariance under certain reflections or rotations---go back to the ancients? Although they didn't have our function concept, they did understand all the isometries of the plane. | |
