The cubit (normally defined as the length from elbow to fingertip) is the most widespread unit of measure from the ancient world. However, ancient cubits vary and not all cubits are defined as the distance from elbow to fingertip. Investigation reveals the cubit length to be anywhere from 17 to 24 inches. Cubits are classified into two main groups—long and short. Generally, the short cubit was used for commercial purposes while the longer length was incorporated in building and architecture.
The cubit was originally a Sumerian, and later an Egyptian, measure which was adopted by many of the surrounding cultures. The copper bar cubit of Nippur identifies the Sumerian cubit as 517mm (20.4 inches).
In Egypt, both a common (short) cubit and a longer Royal or Sacred cubit emerged. The common Egyptian cubit was the length of the forearm from the elbow to the tip of the middle finger (about 18 inches). This common cubit is also found throughout Biblical literature. It was divided into the span of the hand (one-half cubit), the palm or width of the hand (one sixth), and the digit or width of a finger (one twenty-fourth). The Egyptian Royal or Sacred cubit was longer.
The Egyptian Royal (Sacred) cubit has survived in both wood and stone, as well as in the meticulous dimensions of Egyptian architecture. Preserved in the Cubit Rod of Maya from the time of Tutankhamen, the Royal or Sacred cubit is identified as 20.6 inches. There are 28 ‘digits’ on this 523mm rod, with lines at every fourth digit representing the palm. The earliest Egyptian monuments used this same cubit length which shows the Royal Egyptian Cubit remained accurate for thousands of years.
Undoubtedly, the most important reference for the royal cubit length is the King’s Chamber in the Great Pyramid. It is the most accurately wrought, the best preserved, and the most exactly measured of all the data that are known. The cubit in the Great Pyramid is 523mm (20.62 inches).
According to the astrophysicist Hans Becker, the resonant frequency of the Royal/Sacred cubit is 144,000 Hz—a harmonic of the speed of light. It is considered by some to be an antenna for cosmic frequencies.
Lost Cubit was identified in 2000 by Hans Becker during his work with Slim Spurling. According to Becker, the Lost Cubit is a previously unrecognized cubit length that may have been deliberately omitted from ancient records due to its powerful significance. It resonates at 177,000 Hz. Due to its dual ability to resonate with cosmic energy frequencies and earth energy frequencies, the Lost Cubit is considered by some to have properties that may affect DNA and longevity.
