where did the expression beat a dead horse come from
Flogging a dead horse According to the Oxford English Dictionary,[1] the first recorded use of the expression in its modern sense was by the English politician and orator John Bright, referring to the Reform Act of 1867, which called for more democratic representation in Parliament. Trying to rouse Parliament from its apathy on the issue, he said in a speech, would be like trying to flog a dead horse to make it pull a load. The Oxford English Dictionary cites The Globe, 1872, as the earliest verifiable use of flogging a dead horse, where someone is said to have "rehearsed that [. . .] lively operation known as flogging a dead horse".[2]
