Roma Eterna
Robert Silverberg
 The novel is presented as a series of vignettes over a period of about 1500 years, from 1282 ab urbe condita (AD 529) to 2723 AUC (AD 1970). Most of the story-chapters involve Roman politics, either the competition between the Western and Eastern Empires to dominate the other or the violent creation of the Second Roman Republic in about 2603 AUC (AD 1850). Others describe the first Roman circumnavigation of the world and unsuccessful attempts to conquer Nova Roma (North America). Many features of our own history are repeated in this history, though under changed circumstances: The equivalent of the 16th and 17th Centuries have bold navigators and adventurers, romanticised by later generations but unpleasantly brutal and ruthless when looked at closely; in the late 18th to mid-19th Centuries, a decadent old order is overthrown by revolution followed by a reign of terror and the reemergence of Republicanism; though Italy remains a central part of the Roman Empire, the Latin dialect spoken there develops into a kind of Italian, and the name "Marcus" changes into "Marco"; though Vienna is a provincial capital which never had an Emperor of its own, its population dances the Waltz; by the 20th Century, people travel by cars rather than carriages and by the second half of the century, space flight is achieved. It concludes with the first story to be written, when a group of Hebrew citizens in Alexandria prepare to depart Earth in a rocket which explodes shortly after takeoff. But they will try again, still believing God chose them to inherit the Promised Land, just not on Rome-dominated Earth.
