ローマ帝国衰亡史
The novel's title is a contraction of Edward Gibbon's "The History of the Decline and Fall of the Roman Empire." The title alludes also to the German philosopher Oswald Spengler's "The Decline of the West" (1918–1922), which first appeared in an English translation in 1926 and which argued, among other things, that the rise of nations and cultures is inevitably followed by their eclipse.
