The illustrations (with the exception of the second, which is taken from a photograph of the antique) have been adapted from a series Of designs, published early in this century, by Pinelli, a Roman artist (i781 — is3s), who ac quired a considerable reputation among his countrymen, especially for the power of repre senting energetic action. I may be allowed to express my great obligations to the pains and skill (to which indeed this volume is otherwise much indebted) which have been used in making these designs available for the present purpose.
