What dynasty did Imhotep rule in?

Answer 1

Imhotep was an Egyptian polymath, who served under the Third Dynasty king Djoser as chancellor to the pharaoh and high priest of the sun god Ra at Heliopolis. He is considered to be the first architect and engineer and physician in early history though two other good physicians, Hesy-Ra and Merit-Ptah lived around the same time.

Imhotep was one of very few mortals to be depicted as part of a pharaoh's statue. He was one of only a few commoners ever to be accorded divine status after death.
