(so called of its shining) occurs only in (John 18:3) (It there probably denotes any kind of covered light, in distinction from a simple taper or common house-light, as well as from a flambeau. Lanterns were much employed by the Romans in military operations. Two, of bronze, have been found among the ruins of Herculaneum and Pompeii. They are cylindrical, with translucent horn sides, the lamp within being furnished with an extinguisher.—ED.)

<p>lan'-tern (phanos, phaino, "to give light"): Lanterns were carried by the mob which arrested Jesus in Gethsemane (Joh 18:3, probably better "torches"). The word "lantern" in the time of early versions had a much wider significance than now. The Romans, however, had lanterns in the times of Christ, made by use of translucent skins, bladders, or thin plates of horn.</p>
