They are made of cut stones, and the technique of which traces back to Hellenistic tradition. New measurements confirm that these domical vaults with pendentives form a hemisphere. They were probably constructed in the second century AD. A shallow dome made of cut stone voussoir was adequate to create a geometrical form, but it was considerably inapplicable to a monument more than 10 m in diameter. This method was a tentative solution before the pendentive dome was innovated in the second half of the sixth century AD., https://www.jstage.jst.go.jp/article/aija/78/693/78_2387/_article/-char/ja/},
