The History of The Decline and Fall of the Roman Empire, a major literary achievement of the 18th century published in six volumes, was written by the celebrated English historian Edward Gibbon. Volume I was published in 1776, and went through six printings (a remarkable feat for its time). Volumes II and III were published in 1781; volumes IV, V, VI in 1788-89. The original volumes were published as quartos, a common publishing practice of the time.
