Roma Eterna

Roma Eterna is a science fiction fixup novel by American writer Robert Silverberg, published in 2003, which presents an alternative history in which the Roman Empire survives to the present day. Each of the ten chapters was first published as a short story, six of them in Asimov's Science Fiction, between 1989 and 2003.

Plot introduction
The point of divergence is the failure of the Israelite Exodus from Egypt. Moses and many of the Israelites drowned, and the remnant, led by Aaron, were fetched back to slavery in Egypt, a traumatic event recorded for posterity in the Book of Aaron, an alternate version of the Bible. Later, the Hebrews were freed from bondage and remained a distinct religious-ethnic minority in Egypt, practicing a monotheistic religion, up to the equivalent of our 20th century (the 27th century of the Roman calendar).

Still, affairs of the larger world and the rise and fall of empires and cultures remained roughly the same as in our history until the division of the Roman Empire, which was never Christianised in this history. Mutual assistance between the Western and the Eastern Roman Empire against barbarian invasions preserved both from falling and kept Roman rule intact throughout the imperial dominions.

Despite the absence of Christianity, which, in our history, considerably influenced early Islam, Muhammad still started his prophetic career but was assassinated by a perceptive Roman agent, nipping Islam in the bud and thus precluding the spread of any monotheistic religion through the Roman Empire. Monotheism remained limited to the specific Hebrew sect in Egypt.

Plot summary
The novel is presented as a series of vignettes over a period of about 1500 years, from to. 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. Others describe the first Roman circumnavigation of the world and unsuccessful attempts to conquer Nova Roma (Central 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.

Literary significance and reception
The book received a share of negative criticism. It was accused of concentrating too much on the upper class and not drawing a detailed picture of Roman life and its change through the ages. The only story in the book to receive true praise from reviewer Alma A. Hromic is the last chapter, To the Promised Land, which incidentally, does not deal with Romans or the upper class of the Empire.

Five of the stories in the series, "Waiting for the End," "Getting to Know the Dragon," "A Hero of the Empire," "With Caesar in the Underworld," and "The Reign of Terror" were nominated for the Sidewise Award for Alternate History upon their original publications, although none of the stories won.
