Fun, short, simple and in full colour! You won't end up knowing the list of the 4th century emperors, but you'll never again confuse a Roman legionary of Augustus with one of Constantine, and one of Constantine with a Viking. Weapons and helmets, formations, logistics, their families or religion, explained in a few lines and with more than 50 drawings which fill these pages with life. Nothing else is intended. Watch to learn. For those who already know the period, it might seem brief, for the rest it opens the doors to the most unknown and decisive period of the Roman Empire; and well, the drawings are so cute...
