This is a close up taken of the Buddha faces in Angkor Wat, Cambodia.
Unlike many of the Buddhas I saw in China which were carved out in situ from a big piece of rock, the statues here were assembled from blocks of rock stacked together.
This begs two questions. For one, how to control the carving so that the profiles and details match with the adjoining blocks and that when assembled together give the 3D they want.
Secondly, how did transport, lift and stack the heavy blocks together?
While we were there, we were just bewildered!
