This 1,500-year-old Cave in India was Carved out of a Giant Boulder.This is Lomas Rishi Cave, one of several man-made Barabar Caves. The Barabar Hill Caves ( बराबर, Barābar) are the oldest surviving rock-cut caves in India, dating from the Maurya Empire (322–185 BCE), some with Ashokan inscriptions, located in the Makhdumpur region of Jehanabad district, Bihar, India, 24 km (15 mi) north of Gaya.The cave of Lomas Rishi is probably the most famous of the caves of Barabar, because of its beautifully carved door. It is on the southern side of Barabar granite hill, and is adjacent to Sudama cave, which is on the left. Lomas Rishi consists of two rooms: a rectangular room measuring 9.86×5.18m, and a circular, semi-hemispherical room 5m in diameter, which is accessed from the rectangular room by a narrow rectangular passage.This cave has an arched facade that probably imitates contemporary wooden architecture. On the periphery of the door, along the curve of the architrave, a line of elephants advances in the direction of stupa emblems. This is the characteristic form of the “Chaitya arch” or chandrashala, to be an important feature of architecture and sculpture in the rock for many centuries. It is clearly a stone reproduction of wooden buildings and other plant materials.
