According to the Sthapatya Veda (the Indian tradition of architecture), the temple & the town should mirror the cosmos. The temple architecture & the city plan are, therefore, related in their conception.
The Temple represents the outer & the inner cosmos. The outer cosmos is expressed in terms of various astronomical connections between the temple structure & the motions of the sun, the moon, & the planets. The inner cosmos is represented in terms of the consciousness at the womb of the temple & various levels of the superstructure that correspond to the states of consciousness.
The temple must be seen as a structure that gives us considerable information about the science & cosmology of its times. Regarding technology behind the constructions, one must look at each structure separately & see how it fits in the evolving techniques of design & artistic representation across the region.
This fantasy concept artwork exactly mirrors such a Temple of Time.
