Medals give a very great light to history in confirming such passages as are true in old authors, and settling such as are told after different manners.
If we consider the different occasions of ancient and modern medals, we shall find that they both agree in recording the great actions and successes in war; allowing still for the different ways of making it and the circumstances that attended it.
Among the Romans, to preserve great events upon their coins, when any particular piece of money grew very scarce it was often recoined by a succeeding emperor.
The figures of many ancient coins rise up in a much more beautiful relief than those on the modern; the face sinking by degrees in the several declensions of the empire till, about Constantines time, it lies almost even with the surface of the medal.
Nothing can be more pleasant than to see virtuosos about a cabinet of medals, descanting upon the value, rarity, and authenticalness of the several pieces.
