later. Early Jain and Buddhist literature, along with Kautilya's Arthashastra, describe structures, embellishments and designs of these temples – all with motifs and deities currently prevalent in Hinduism. Bas-reliefs and murtis have been found from 2nd to 3rd century, but none of the temple structures have survived. Scholars theorize that those ancient temples of India, later referred to as Hindu temples, were modeled after domestic structure – a house or a palace. Beyond shrines, nature was revered, in forms such as trees, rivers, and stupas, before the time of Buddha and Vardhamana Mahavira. As Jainism and Buddhism branched off from the religious tradition later to be called Hinduism, the ideas, designs and plans of ancient Vedic and Upanishad era shrines were adopted and evolved, likely from the competitive development of temples and arts in Jainism and Buddhism. Ancient reliefs found so far, states Michael Meister, suggest five basic shrine designs and combinations thereof in 1st millennium BCE: A raised platform with or without a symbol A raised platform under an umbrella A raised platform under a tree A raised platform enclosed with a railing A raised platform inside a pillared pavilion Many of these ancient shrines were roofless, some had toranas and roof. From the 1st century BCE through 3rd century CE, the evidence and details about ancient temples increases. The ancient literature refers to these temples as Pasada (or Prasada), stana, mahasthana, devalaya, devagrha, devakula, devakulika, ayatana and harmya. The entrance of the temple is referred to as dvarakosthaka in these ancient texts notes Meister, the temple hall is described as sabha or ayagasabha, pillars were called kumbhaka, while vedika referred to the structures at the boundary of a temple. With the start of Gupta dynasty in the 4th century, Hindu temples flourished in innovation, design, scope, form, use of stone and new materials as well as symbolic synthesis of culture and dharmic principles with artistic expression. It is this period that is credited with the ideas of garbhagrha for Purusa, mandapa for sheltering the devotees and rituals in progress, as well as symbolic motifs relating to dharma, karma, kama, artha and moksha. Temple superstructures were built from stone, brick and wide range of materials. Entrance ways, walls and pillars were intricately carved, while parts of temple were decorated with gold, silver and jewels. Visnu, Siva and other deities were placed in Hindu temples, while Buddhists and Jains built
