Known in Sinhalese as Sandakada Pahana (Lamp), it is roughly translating into English as moonstone. The name is based on its shape and design. The first Moonstone was creating during the latter stage of the UNESCO ancient Anuradhapura Kingdom.
The carvings of the semi-circular stone slab were the same in every Sandakada Pahana. A half lotus was carving in the center, which enclosed by several concentric bands. Indeed, the first band from the half lotus is decorating with a procession of swans, followed by a band with an intricate foliage design known as liyavel. So, the third band has carvings of four animals; elephants, lions, horses, and bulls. These four animals follow each other in a procession symbolizing the four stages of life: growth, energy, power, and forbearance. The fourth and outermost band contains a carving of flames, usually interpreted as representing a fire altar.
