Jean Foy Vaillant (1632–1706) was a scholarly French numismatist and collector of coins who authored a large number of important numismatic works on ancient coins. The work at hand went through several editions, culminating in the 1743 imprint, revised and edited by J.F. Baldini. Numismata imperatorum romanorum is Vaillant's most notable contribution to numismatics, and this, the last edition published during his lifetime, is perhaps the scarcest.
