I've lost count of how many times I've read this book and had to replace it at least once. De Camp's depiction of the life, events and people of post-Imperial Italy are dead on accurate as far as I can tell, and the fictional aspect of the work is highly engaging.
The book gives away its 1938 vintage, when the protagonist Martin Padway is able to exchange about $5.00 worth of modern Italian coins for 93 post-Imperial silver sesterces, enabling him to survive his first 72 hours in old Rome. He could do this, of course, because in 1938 Italy, like most countries, still circulated real silver coins. I can't help wondering how the protagonist would have fared if he only had today's inflated zinc and tin tokens?
