    The Beautiful Cubit System I Douglas 2019 The Beautiful Cubit System Ian Douglas, B.Sc [email protected] 30 June 2019 Version 1.0.0 DOI: https://doi.org/10.5281/zenodo.3263864 This work is licensed under the Creative Commons Attribution 4.0 International License. Abstract An analysis of the Egyptian Royal cubit, presenting some research and opinions flowing from that research, into what I believe was the original cubit, and how it was corrupted. I show various close arithmetic approximations and multiple ways of getting the divisions of the cubit, as well as some related measures. The cubit also encapsulates the basic components for the metric system. Keywords: Egyptology, metrology, royal cubit, cubit, metre, foot, metric system Contents 1. Introduction 2. Overview of current understanding 3. An alternative origin 4. Different ways of approximating the royal cubit 5. Different ways of getting the cubit divisions 6. Geometry, the Royal Cubit and the metric system 7. Bibliography 1. Introduction The cubit is a well-know ancient measure of length, used around various places in the Middle East and Mediterranean region in the distant past. 1 The Beautiful Cubit System I Douglas 2019 It is allegedly based on the length of a human (male) fore-arm. It is typically measured from the back of the elbow to some point between the wrist and the end of the outstretched middle finger, or in some variants, a point beyond that. The problem with this approach is that everyone’s arm is a different length. If the heights of the dynastic Egyptians is taken as representative, then their arms would have been too short to justify the accepted lengths.

    103 SAXON BUILDI NG MEASUREMENTS P.J.Hu99 ins 27 Grange Court, Waltham ~bbey, ~ssex. Abstract The medieval ~nglish rod of 5.OJ m has been shown to have been in use back to the 6th c~ntury.The sub-divi'sions so fa.r detected are thirds and sixths of this .rod. '1',10 particular a.spects are considered in this paper. The first is vhether the rod was divided further into feet; it is suggested that the manupes-the foot measured by hand-at 15 to the rod is the likely contender. The second aspect concerns building data from r-Juckine. At least 66 Saxon post-hole buildings have been analysed and, provisionally, it appears that 40 were set out using a rod of about 4.65 m and 25 using the 5.03 m rod. Extant rods in the Saxon bomeland likewise have a mean value of 4.65 m suggesting this measure Has brought over by the original Saxon settlers at Bucking. Introduction In a developing sub'ject new ideas are formula.ted and old ideas rightly questioned and possibly discarded. Ne," data may support established hypotheses or change or add to the picture. At any particular time one or hvo aspects of a developing subject will appear to be of special importance in a \vorker t s mind. Such is the position at the present time. The first as~ect of current interest is whether or not the 5.03 m rod, used in the Saxon period, was divided into feet. The second aspect concerns a site '''here two measuring systems appear to have been in use.

  • English Customary Weights and Measures
    English Customary Weights and Measures Distance In all traditional measuring systems, short distance units are based on the dimensions of the human body. The inch represents the width of a thumb; in fact, in many languages, the word for "inch" is also the word for "thumb." The foot (12 inches) was originally the length of a human foot, although it has evolved to be longer than most people's feet. The yard (3 feet) seems to have gotten its start in England as the name of a 3-foot measuring stick, but it is also understood to be the distance from the tip of the nose to the end of the middle finger of the outstretched hand. Finally, if you stretch your arms out to the sides as far as possible, your total "arm span," from one fingertip to the other, is a fathom (6 feet). Historically, there are many other "natural units" of the same kind, including the digit (the width of a finger, 0.75 inch), the nail (length of the last two joints of the middle finger, 3 digits or 2.25 inches), the palm (width of the palm, 3 inches), the hand (4 inches), the shaftment (width of the hand and outstretched thumb, 2 palms or 6 inches), the span (width of the outstretched hand, from the tip of the thumb to the tip of the little finger, 3 palms or 9 inches), and the cubit (length of the forearm, 18 inches). In Anglo-Saxon England (before the Norman conquest of 1066), short distances seem to have been measured in several ways.

  • The English Measurement System
    THE ENGLISH MEASUREMENT SYSTEM The measurement system commonly used in the United States today is nearly the same as that brought by the colonists from England. These measures had their origins in a variety of cultures –Babylonian, Egyptian, Roman, Anglo-Saxon, and Norman French. The ancient "digit," "palm," "span" and "cubic" units of length slowly lost preference to the length units "inch," "foot," and "yard." Roman contributions include the use of 12 as a base number (the foot is divided into 12 inches) and the words from which we derive many of our present measurement unit names. For example, the 12 divisions of the Roman "pes," or foot were called unciae. Our words "inch" and "ounce" are both derived from that Latin word. The "yard" as a measure of length can be traced back to early Saxon kings. They wore a sash or girdle around the waist that could be removed and used as a convenient measuring device. The word "yard" comes from the Saxon word "gird" meaning the circumference of a person’s waist. Standardizing various units and combining them into loosely related systems of measurement units sometimes occurred in fascinating ways. Tradition holds that King Henry I decreed that a yard should be the distance from the tip of his nose to the end of his outstretched thumb. The length of a furlong (or furrow-long) was established by early Tudor rulers as 220 yards. This led Queen Elizabeth I to declare in the 16th century, that henceforth the traditional Roman mile of 5000 feet would be replaced by one of 5280 feet, making the mile exactly eight furlongs and providing a convenient relationship between the furlong and the mile.

  • Ancient Egyptian Cubits – Origin and Evolution
    Ancient Egyptian Cubits – Origin and Evolution by Antoine Pierre Hirsch A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Near and Middle Eastern Civilizations University of Toronto © Copyright by Antoine Pierre Hirsch 2013 i Ancient Egyptian Cubits – Origin and Evolution Antoine Pierre Hirsch Doctor of Philosophy Near and Middle Eastern Civilizations University of Toronto 2013 Abstract This thesis suggests that prior to Ptolemaic and Roman times, ancient Egypt had two distinct and parallel linear systems: the royal system limited to official architectural projects and land measurements, and a great (aA) system used for everyday measurements. A key 1/3 ratio explains ancient Egyptian linear measurements and their agricultural origin. Emmer is 1/3 lighter than barley, consequently, for an equal weight, a container filled with emmer will be 1/3 greater than a container filled with barley. The lengths derived from both containers share the same 1/3 ratio. The second chapter, Previous Studies, lists the work of scholars involved directly or indirectly with ancient Egyptian metrology. The third chapter, The Royal Cubit as a Converter and the Scribe’s Palette as a Measuring Device, capitalizes on the colour scheme (black and white on the reproduction of Appendix A) appearing on the Amenemope cubit artifact to show the presence of two cubits and two systems: the black (royal system) and the white (great [aA] system) materialized by the scribe's palette of 30, 40, and 50 cm. The royal cubit artifacts provide a conversion bridge between the royal and the great systems. The information derived from the visual clues on the Amenemope cubit artifact are tested against a database of artifacts scattered in museums around the world.

    1 St Robert of Knaresborough Knaresborough Schools Project 2019 Maths and Measurement St Robert – Schools Project 2019: Maths and Measurement 2 THE CRAZY WORLD OF MEDIEVAL MEASUREMENTS: USE YOUR BODY Resources: Poppy seeds (possibly two small and messy), Barley, Rulers (cms and inches), Tape Measures (cms and inches); fingers, hands and arms; a range of things to measure TEACHER – Guide for introduction: Today, we can all agree how long or wide something is because we have an agreed set of measurements. We all have a ruler or a tape measure with exactly the same measurements on so we don’t have to worry or argue about things too much. But in the time of St. Robert, things were much more complicated. It was much harder to agree on sizes, lengths and distances. Discussion: Why was it harder to measure things accurately a long time ago than it is today? Who decides how long a centimetre or a metre, an inch or a mile is? And the same goes for how heavy something is – who decided what a kilogram or a pound was? And how large something is – a litre or a pint? How do we agree on these things? And why are these things important? Focus on measuring how long something is and consider some of the following: • People had a lack of interest as it didn’t matter much how tall you were in numbers – people could see how tall you were and could make an easy comparison with someone or something; people knew their local area and knew the distance or area of things; • Most people could not read or write although they had very good memories, were good with
