True lamps, not bowls modified to be used as lamps, were first made in the Middle Bronze I period (2250–2000 B.C.). The designs, probably brought to Canuan by settlers from the north, included four spouts serving as wick-rests; some had flatter bases than the earlier bowl-lamps. By folding four flaps of the soft clay toward the center of the lamp, wick-rests were created at the corners formed between turned-in flaps.
