The Land Leviathan is a novel by Michael Moorcock [1]. Originally subtitled "A New Scientific Romance", it has been seen as an early steampunk novel, dealing with an alternative British Imperial history dominated by airships and futuristic warfare. It is a sequel to The Warlord of the Airand is also published in the compilation volume the Warlord of the Air.
The story of Oswald Bastable's continuing adventures "trapped forever in the shifting tides of time" is framed with the conceit of the book being a long lost manuscript, as related by Moorcock's grandfaster. The elder Moorcock travels to China in an attempt to track down Bastable, meeting Una Persson of the Jerry Cornelius novels on the way.
Bastable's story takes in a South Africa ruled by Ghandi, a 'Black Attila' leading an African army on a conquest of Europe and an apolcalyptic war against the United States featuring the "vast, moving ziggurat of destruction" of the title.
It was first published in 1974 and has remained in print, in various editions, ever since.
