57. The Marquis Maffei has examined the siege and battle of
Verona with that degree of attention and accuracy which was
due to a memorable action that happened in his native
country. The fortifications of that city, constructed by
Gallienus were less extensive than the modern walls, and the
amphitheatre was not included within their circumference.
