Lanterns were portable sources of light used to illuminate caves, tunnels, etc.

French Assassin Arno Dorian used lanterns to find his way around the caves underneath Saint-Denis, clearing the way of bats and insects. If Arno were to fall into water, his lantern would be disabled until he dipped it in oil.
Arno also used the Head of Saint-Denis as a lantern, which didn't have to be dipped in oil.
