Blood of Jesus Christ, or Blood of Christ, was a military order instituted at Mantua by Vincenzo I Gonzaga, Duke of Mantua, and approved by Pope Paul V, on 25 May 1608. The devise of this order was, Domine probasti me, or that Nihil hoc triste recepto. Hermant speaks of this order, and observes that it took its name from some drops of the blood of Jesus, said to have been preserved in the cathedral church of Mantua. Their number was restricted to twenty, besides the Grand Master; the office whereof was attached to himself and his successors.
There was also a congregation of nuns in Paris called Blood of Jesus Christ, reformed from the Cistercians.
