Letter to János Bolyai (4 April 1820) Published in: Samu Benkő (ed.), Bólyai-levelek, Kriterion, 1975, p. 123 As quoted in: O'Connor, John J.; Robertson, Edmund F., "Farkas Bolyai", MacTutor History of Mathematics archive, University of St Andrews. Having himself spent a lifetime unsuccessfully trying to prove Euclid's fifth postulate, Farkas discouraged his son János from any further attempt. No monument should stand over my grave, only an apple-tree, in memory of the three apples; the two of Eve and Paris, which made hell out of earth, and that of I. Newton, which elevated the earth again into the circle of heavenly bodies.
