Provenance: Yes, all three came from the same collection. My grandparents’ estate, New England, USA. They were avid collectors and world travelers. I wish i could tell you more. I am not an expert and i am only guessing based on what my grandfather used to call them (whale fat oil lamp) At one point he had them all cataloged (hence the #s on the bottom). I do not have any of his records about the lamps. They had hundreds of oil lamp Technology Ancient Lamps The earliest use of stone lamps seems to have arisen approximately 15,000 to 20,000 years ago. Ancient stone lamps have been discovered in the ancient caves at Lascaux and seemed to have been used to illuminate the cave walls for the extensive cave paintings. These early lamps were carved out of indigenous stone and used animal fats for fuel. A small cavity held the oil and the lamp was initially wickless. But by 8,000 B.C. plant-based oils started to appear particularly olive oil. Olives began to be cultivated in the Middle East where they later spread throughout the Mediterranean region. It proved to be a good flame source because it was easy and inexpensive to manufacture and produced a fair amount of light. In the northern climates where the olives couldn’t grow animal-based fats remained popular.
