Lest Darkness Fall

Martin Padway, 20th-century archaeologist, becomes a reluctant one-way time-traveller, landing in Rome on the verge of the Dark Ages. With no way home, he sets out to make the world he's in a better place. In short order, Padway "invents" and introduces such things as Printing and newspapers, Arabic numerals, Double entry bookkeeping, Copernican astronomy, and, most important—Distilling. And the world of decaying Rome will never be the same!
