What is a Ell and a Cubit (Royal/Egyptian)?
The Ell is an historical unit of length, primarily used for measuring cloth and textiles. Its exact length varied considerably depending on the region, country, and time period, making it a non-standardized unit overall, though often legally defined within specific jurisdictions.
It is generally understood to have originated from the length of the arm or forearm, similar to the cubit. The name itself derives from the Proto-Germanic word *alinō, meaning "forearm".
Common historical values demonstrate this variability:
- English Ell: Traditionally 45 inches (1.25 yards, exactly 1.143 meters). This was the most common ell in England, particularly for measuring imported Flemish cloth.
- Scottish Ell: Approximately 37.06 inches (about 0.941 meters), based on the standard Scottish inch.
- Flemish (or Brabant) Ell: Approximately 27 inches (about 0.686 meters). Widely used in the Low Countries, a major center for textile production.
- French Ell (Aune): Varied, but often around 46.77 inches (about 1.188 meters) in Paris. The aune itself had different lengths in different French regions.
- Polish Ell (Łokieć): Approximately 22.7 inches (about 0.576 meters).
- Swedish Ell (Aln): Approximately 23.3 inches (about 0.593 meters).
The Royal Cubit (Ancient Egyptian: meh nesut) was the primary ancient Egyptian standard unit of linear measure. It was based on the length of the forearm from the elbow to the tip of the extended middle finger, plus the width of the palm. It is considered one of the earliest attested standard units of measurement.
The Royal Cubit was typically divided into 7 palms (shesep), with each palm further divided into 4 digits or fingers (djeba), totaling 28 digits. Its length varied slightly over time and location but is generally accepted to be approximately 52.3 to 52.9 centimeters (about 20.6 to 20.8 inches). A common average value used is 0.524 meters.
A shorter Common Cubit or Short Cubit (Ancient Egyptian: meh sherer) also existed, measuring 6 palms (24 digits), approximately 45 cm.
Note: The Ell is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Cubit (Royal/Egyptian) belongs to the imperial/US customary system.
History of the Ell and Cubit (Royal/Egyptian)
The ell was a fundamental unit for the textile trade across Europe, flourishing from the medieval period through the early modern era and into the 19th century. Its origins likely lie in anthropomorphic measurements related to the arm, similar to the cubit.
The lack of a universal standard led to numerous regional variations. Different cities, guilds, or nations established their own "standard" ell, often physically represented by a metal rod kept by authorities. This variation could sometimes be a source of trade disputes but also reflected local manufacturing and trade practices.
The English ell of 45 inches (longer than the standard English yard of 36 inches) became particularly well-established, possibly to account for shrinkage or to provide a customary "bonus" measure when selling cloth.
With the rise of standardized measurement systems like the Imperial system (promoting the yard) and especially the Metric system (introducing the meter), the ell gradually became obsolete during the 18th and 19th centuries. Legal reforms in many countries formally abolished it in favor of metric units.
The Royal Cubit emerged very early in Egyptian history, likely during the Predynastic or Early Dynastic Period (before 3000 BCE). Its standardization was crucial for the large-scale construction projects undertaken by the pharaohs.
- Early Standardization: It represents one of history's first successful attempts at creating and maintaining a standard unit of length, essential for architectural precision and administrative consistency.
- Cubit Rods: Physical standards, known as cubit rods, were created from durable materials like wood, slate, or granite. These rods were often inscribed with subdivisions (palms, digits, and sometimes fractions of digits) and sometimes bore dedications or official insignia. Examples have been found in tombs, such as that of Tutankhamun, and likely served as official benchmarks.
- Monumental Construction: The Royal Cubit was the fundamental unit used in the design and construction of temples, palaces, and most famously, the pyramids. The precise dimensions of structures like the Great Pyramid of Giza reflect careful measurement using this standard.
- Longevity: The Royal Cubit remained the standard measure in Egypt for millennia, from the Old Kingdom through the Ptolemaic period and into Roman times, demonstrating remarkable stability.
Common Uses for ells and cubits
Explore the typical applications for both Ell (imperial/US) and Cubit (Royal/Egyptian) (imperial/US) to understand their common contexts.
Common Uses for ells
The ell is now obsolete but was historically crucial for:
- Textile Trade: Its primary and defining use was measuring and selling lengths of cloth (wool, linen, silk, etc.). Cloth was often priced and sold "by the ell".
- Tailoring and Dressmaking: Used by artisans creating garments.
- Mercantile Records: Appears frequently in historical merchant accounts, inventories, customs documents, and trade records. Understanding the local ell is vital for interpreting these economic historical sources.
- Land Measurement (Rarely): In some specific, localized contexts, an ell might have been used for land, but this was uncommon compared to units like the rod or chain.
- Literature and Culture: Referenced in historical texts, literature, and idioms (e.g., "Give him an inch, and he'll take an ell").
Common Uses for cubits
The Royal Cubit was integral to many aspects of ancient Egyptian society:
- Architecture and Construction: Defining building dimensions, column heights, room layouts, and overall structural proportions.
- Land Surveying: Measuring fields for agriculture, taxation, and property boundaries, especially after the annual Nile flood receded.
- Record Keeping: Used in administrative documents, inventories, and calculations.
- Craftsmanship: Measuring materials like stone blocks, timber, rope, and textiles.
- Art and Iconography: Used to establish proportions in statues and reliefs according to canonical rules.
- Religious and Funerary Contexts: Cubit rods were sometimes included in tomb equipment, possibly symbolizing order and correctness or serving a practical purpose in the afterlife.
- Historical Texts: The term "cubit" appears in various ancient texts, including the Bible, though the specific length intended (Egyptian Royal, common, Babylonian, etc.) can be context-dependent.
Frequently Asked Questions
Questions About Ell (ell)
How long is an Ell?
There is no single fixed length for the ell; it varied significantly by location and time. Some key examples include:
- English Ell: 45 inches (1.143 m)
- Scottish Ell: ~37 inches (~0.94 m)
- Flemish Ell: ~27 inches (~0.69 m)
- French Aune (Ell): ~47 inches (~1.19 m) Always check the context (region and era) when encountering a measurement in ells. The English ell of 45 inches is often assumed in English-language historical contexts unless otherwise specified.
How does the Ell compare to a Yard?
The English ell (45 inches) is exactly 1.25 times longer than the standard yard (36 inches). However, other ells could be shorter (like the Flemish ell) or have different relationships to the local yard equivalent.
Is the Ell related to the Elbow or Arm?
Yes, the name "ell" derives from Proto-Germanic *alinō ("forearm"), cognate with Latin ulna and Greek ōlénē, all referring to the forearm or elbow. This strongly suggests an origin based on the length of the human arm, similar to the cubit. However, the standardized lengths adopted for trade were often considerably longer than a literal forearm.
Why did the Ell length vary so much?
The variation stemmed from:
- Lack of Universal Standards: Before the metric system, measurement standards were highly localized.
- Regional Customs: Different areas developed their own traditional lengths based on local needs and practices.
- Trade Protectionism: Sometimes, variations were maintained deliberately by guilds or cities.
- Evolution Over Time: The definition could change even within the same region over centuries.
Is the Ell an SI unit?
No, the ell is not part of the International System of Units (SI). It is an historical, customary unit belonging to various pre-metric systems. The corresponding SI unit for length is the meter (m).
Is the Ell still used today?
No, the ell is obsolete and is not used for any standard commercial, scientific, or practical measurements today. Its use was superseded primarily by the yard (in Imperial/US customary systems) and the meter (in the metric system). Its relevance is now purely historical.
About Cubit (Royal/Egyptian) (cubit)
How was the Royal Cubit standardized?
Standardization was achieved through the creation and maintenance of master cubit rods. These physical exemplars, often made of durable stone like granite, were likely kept in major temples or administrative centers. Officials and craftsmen would use copies made from these masters for practical work. The rods themselves were meticulously marked with the primary divisions of 7 palms and 28 digits, often including finer subdivisions. This system ensured consistency across large projects and different regions of the kingdom.
What is the difference between a short cubit and a royal cubit?
The two main cubit measures in ancient Egypt were:
- Short Cubit (meh sherer): Measured 6 palms (24 digits), approximately 44.7 to 45 cm (around 17.6 inches). It represented the distance from the elbow to the tip of the thumb or closed fist. It was likely used for more common, everyday measurements of cloth, goods, or smaller objects.
- Royal Cubit (meh nesut): Measured 7 palms (28 digits), approximately 52.3 to 52.9 cm (around 20.6 inches). It was the length from the elbow to the tip of the middle finger plus one palm width. This was the official standard used for monumental architecture, land surveying, and significant state projects. It likely held a higher status and was associated with the pharaoh and divine order.
How long was the Royal Cubit?
The Royal Cubit was approximately:
- 0.523 to 0.529 meters (m)
- 52.3 to 52.9 centimeters (cm)
- 20.6 to 20.8 inches (in)
- Roughly 1.72 feet (ft)
A value of 0.524 m is often used as a representative average.
Is the Cubit still used today?
No, the ancient Egyptian Cubit (both Royal and short) is obsolete. It has not been in practical use for centuries, having been replaced by other measurement systems and ultimately by the metric system. Its relevance today is purely historical, archaeological, and academic.
Is the Cubit an SI unit?
No, the Cubit is not an SI unit. It is an ancient, traditional unit of measurement originating in Egypt. The SI base unit for length is the meter (m).
