About this source
What it is
This is an inscription carved into sandstone rock, known as Inscription IV-B, found at the Water Mountain of Djedefre in the New Valley region of Egypt's Western Desert. It records the Horus name and personal name of King Cheops, another name for Khufu.
Why it matters
Inscriptions like this were left by expeditions sent out during a king's reign, often to quarries or distant sites. This one names Khufu directly, making it a rare primary record of his name from his own time, found far from the pyramids most people associate with him.
