What is a Aln and a Cubit (Royal/Egyptian)?
The Aln (Swedish), Alen (Danish and Norwegian) was a traditional Scandinavian unit of length, analogous to the English ell or cubit. Its length varied significantly by region and time but was generally based on the length of the forearm.
Key standardized or common values include:
- Swedish Aln: Officially standardized (as the Rydaholmsaln) in 1665 and confirmed in 1735 as exactly 2 Swedish fot (feet). This equates to approximately 0.5938 meters (or 59.38 cm / 23.38 inches).
- Danish Alen: The common standard (Sjællandsk alen) was 2 Danish fod (feet), equating to approximately 0.6277 meters (or 62.77 cm / 24.71 inches).
- Norwegian Alen: Often followed the Danish standard due to political union. After 1824, it was legally defined as 2 Norwegian fot, equating to 0.6275 meters (or 62.75 cm / 24.70 inches), very close to the Danish value.
The Aln/Alen was typically subdivided into 4 kvarter (quarters).
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 Aln 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 Aln and Cubit (Royal/Egyptian)
The Aln/Alen originates from the Proto-Germanic word for forearm (alinō), reflecting its basis as an anthropomorphic unit, similar to the cubit in other cultures. For centuries, its length was inconsistent, varying between regions, cities, and trades within Sweden, Denmark, and Norway.
- Early Variations: Numerous local standards existed, often based on physical rods kept by authorities or guilds.
- Standardization Efforts:
- Sweden: Attempts at standardization culminated in the adoption of the Rydaholmsaln (based on a specific iron standard bar from Rydaholm church) in 1665, defined as 2 fot. This standard (≈0.5938 m) became mandatory nationwide in 1735.
- Denmark & Norway: The Sjællandsk alen (Zealand ell, ≈0.6277 m) became the dominant standard in Denmark and, consequently, in Norway during their union. Norway later formally adopted a slightly different value (≈0.6275 m) based on its own fot definition in 1824.
- Metrication: The Aln/Alen was officially replaced by the metric system during the 19th and early 20th centuries: Norway in 1875, Sweden in 1889, and Denmark in 1907.
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 alnar and cubits
Explore the typical applications for both Aln (imperial/US) and Cubit (Royal/Egyptian) (imperial/US) to understand their common contexts.
Common Uses for alnar
Historically, the Aln/Alen was a fundamental unit for everyday trade and craft:
- Textiles: Its most prominent use was measuring cloth (wool, linen, silk). Standardization was often driven by the textile trade.
- Timber and Lumber: Measuring lengths of wood.
- Rope and Cordage: Measuring lengths of rope.
- Construction: Used in building measurements, though perhaps less formally than in trade.
- General Trade: Measuring various goods sold by length.
It was less commonly used for land surveying, where units like the stång (rod) or mil (mile) were preferred.
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 Aln (aln)
How long is an Aln/Alen?
There isn't one single value, as it depended on the country and era. The main official standards were:
- Swedish Aln: ~0.594 meters / ~23.4 inches
- Danish Alen: ~0.628 meters / ~24.7 inches
- Norwegian Alen: ~0.628 meters / ~24.7 inches (very close to Danish)
Always consider the context (Swedish, Danish, or Norwegian) when encountering this unit in historical documents.
What's the difference between the Aln in different countries?
The primary difference was length:
- The Swedish Aln (≈59.4 cm) was noticeably shorter than the Danish and Norwegian Alen (both ≈62.8 cm).
- All were typically defined as 2 local fot (feet), but the length of the fot itself varied between the countries.
Is the Aln related to the English Ell?
Yes, both the Aln/Alen and the English Ell are historical units of length derived from the concept of the cubit or forearm length (Latin ulna). However, their standardized lengths differed significantly. The most common English Ell was 45 inches (1.143 m), much longer than any standard Scandinavian Aln/Alen.
Is the Aln/Alen still used today?
No, the Aln/Alen is obsolete. It was officially replaced by the meter in Sweden, Denmark, and Norway during the metrication process in the late 19th and early 20th centuries. Its use today is purely historical.
Is the Aln an SI unit?
No, the Aln/Alen is not an SI unit. It is a traditional unit from the historical Scandinavian systems of measurement. The SI base unit for length is the meter (m).
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).
