sketch: London, Wallace Collection, 14.5" x 25" (36.83 x 63.5 cm.) tapestry: 15' 11" x 24' 5" (485.14 x 744.22 cm.)This tapestry depicts Constantine's defeat of his co-emperor Maxentius in 312 at the Battle of Milvian Bridge. The stone bridge's right arch is interrupted by wooden beams, indicating that Rubens followed Baronio's suggestion that Maxentius tampered with the bridge to trap Constantine. Instead, he was hoist on his own petard when it collapsed early, sending him plummeting into the river, where the weight of his own armor drowned him. Rubens also drew heavily on his own 1615 depiction of the battle of the Greeks and the Amazons, another bridge battle.
