An ancient Roman moulded terracotta pottery oil lamp, known as a slipper lamp. The body of the lamp is typically adorned with a relief design representing decorated and painted foliage ornaments and a raised handle. The lamp is decorated with a raised circle nozzle top. Lamps such as this one are occasionally known as animal head lamps, due to the appearance of the knob on the handle. Its basic function was to provide light through the oil in the tank and the wick that was located in the rostrum. It was also used as a votive and funerary element. Circa: 100 to 200 AD.
