Memphian, mem′fi-an, adj. relating to Memphis, an ancient capital of Egypt.
But history and tradition assert that they were the tombs of the Memphian Kings.
Your Memphian, however, is not at all content to date from 1820.
Cheops, one of the Memphian Kings, built the largest of the Pyramids, and near it are several others not much less in size.
Through the Memphian dark of the tomb cut a spear of light, touching the last stone of the stairway.
