The Scorpion - Volume 1 - The Devil's Mark

Rome the beautiful is dying, the symbol of civilization falling, the
empire burning. Hidden from massacres and looting, a strange meeting
is held by nine families who share the Roman Empire. To retain their
power, they decide to support a new
religion—Christianity—as well as its representative, the
pope. But who are these 9 mysterious families? Later, much later,
it's the Renaissance. Christianity prospers. A brigand called
“the Scorpion” makes a living by unearthing relics in the
depths of the Roman catacombs, which he sells at high prices to
princes and bishops. Trebaldi, a powerful cardinal, takes an interest
in this Scorpion, who is either a creature of the devil... or a
witness to a cursed era who must disappear...This two-volume book
includes "The Pope's Secret".
