„Very few things happen at the right time, and the rest do not happen at all. The conscientious historian will correct these defects.“
— Herodotus ancient Greek historian, often considered as the first historian -484 - -425 a.C.
This statement is not to be found in the works of Herodotus. It appears in the acknowledgements to Mark Twain's A Horse's Tale (1907) preceded by the words "Herodotus says", but Twain was simply summarizing what he took to be Herodotus' attitude to historiography.
