The Status Symbol of Keys Within the Ancient Roman Empire

2 Comments

Metal keys first appeared during the Ancient Roman Empire and were viewed and often flaunted during the period as an indicator of wealth and/or elevated social status, as Ancient Roman keys were typically comprised of bronze or iron, occasionally worn as decorative jewelry (e.g. rings, bracelets, belt attachments etc.), and used primarily to secure high value items (e.g. jewelry boxes, document cases, coin chests etc.) making them both functional tools but also visible reminders of social status and income. Because only the wealthy could afford metal keys within the Ancient Roman Empire, lower socioeconomic classes relied upon more simplistic, wooden lock mechanisms and in many cases left valuable possessions unsecured entirely. Some Ancient Roman keys featured intricate designs (e.g. animal motifs and geometric patterns etc.), personalized and designed to reflect the predilections of the owner of the key and the lock it is designed for. The Latin term for key, which is “clavis”, evolved and came to mean “code” or “solution” over time, which is notable because it demonstrates the period when physical access and security and intellectual access and security became conceptually correlated with one another. Archaeologists and historians have recovered metal keys from Ancient Roman villas, balneae (pronounced “bahl-neh-eye”) which are bathhouses, and burial sites, often discovered alongside personal items (e.g. grooming tools, coins, small religious tokens etc.). The modern day concept of personal security and having exclusive access to one’s belongings and/or information traces its origins back to these early locking mechanisms and keys as what began as a practical intervention for safeguarding valuables laid the foundation for the modern day systems of privacy, ownership, and controlled access to sensitive and/or valuable information or objects

The Origin of Uppercase and Lowercase Letters and the Influence of Typesetting Upon the English Language

Leave a comment

The term “uppercase” and “lowercase” in relation to alphabet letters was derived during the Victorian period within England. Advertising was highly prominent during the 19th century and used ubiquitously by businesses. The poster makers who would serve these businesses would use letters which were essentially stamps, dipped into thick, viscous, oily ink, specifically formulated this way to cling to and transfer cleanly onto coarse paper which was designed to be rough so that it could absorb as much ink as possible. Compositors, which was the name for this particular vocation during the 19th century, would keep their letters in a type case with large letters at the top and small letters at the bottom. The letters were kept in what was effectively a suitcase which did not close which is where the terms “uppercase” and “lowercase” originated from, as the letters were stored in either the upper portion of the type case or the lower portion of the type case. Each individual letter, a block referred to as a “sort”, was cast in metal and crafted backward to be arranged by hand by a skilled craftsperson. The layout of the case, with capital letters in the upper section and lowercase letters in the bottom, was highly pragmatic, as it positioned the most often used letters at the bottom closer to the person setting the typeset. Interestingly, this pragmatism influenced the English language as compositors not only set letters, they also selected when to use punctuation, spacing, and line breaks, all of which shaped how text was read and understood. Because movable type requires physical pieces for every character used, punctuation was to be used deliberately as too many commas, colons, em dashes etc. meant more time spent, more metal used, and more space being taken up upon the page. This physical constraint helped standardize English punctuation use and even influenced sentence structure, encouraging clarity and economy in writing which are themes that have endured into the 21st century

The Fermentation and Manufacturing Process of Ancient Roman Garum (Fish Sauce)

Leave a comment

The Ancient Roman’s created a special fermented fish sauce called “garum”. Garum was highly valuable and in modern times accounting for inflation, garum would cost $1250.00 for 1 liter. Garum was made from nothing more than salt and decayed fish. The original preparation is unknown as the ancient recipes have been lost. The fishes organs and digestive fluids help in the fermentation process. The container which the garum is made in is left in the sun for a few days to allow the process to ferment as much as possible. The oily slush oozing from the fishes organs and digestive enzymes is the garum and it is loaded with nutrients and contains glutamate which triggers chemical receptors on the tongue to make the brain crave more of it. Glutamate is the primary ingredient/component in monosodium glutamate, commonly abbreviated as “MSG”, and is used by many chefs all over the world

The Origin of the Excalibur Sword Mythology

Leave a comment

In 1136 A.D., a Welsh cleric named Geoffrey of Monmouth while traveling through South Wales, wrote a chronicle entitled “Historia Regum Brittaniae” (pronounced “his-tor-ee-yah ray-gum brit-ann-ee-eye”) which means the “History of the Kings of England” in Latin. This compendium was a clever weave of historical facts and fantastical tales, and the text did a great deal to reignite the legend of King Arthur and his Knights of the Round Table. Geoffrey wrote of Caliburnus which is translated to “Excalibur” in English, the mythical sword which provided Arthur the destiny to rule over England. Geoffrey accounts that the sword was forged upon the Isle of Avalon which would “carve the souls from out of them with blood”. Excalibur is an excellent demonstration of how highly the English venerated their swords, with other western cultures following suit

The Discovery of Pulsar Stars

Leave a comment

Neutron stars were thought to be preposterous when first suggested until 1967 when scientists used radio-antenna telescopes to map the universe. 3 pulses would be unusual, 4 pulses would be phenomenal, but scientists had received pulses from certain parts of the universe 24 hours per day, 7 days per week for months on end. The reason the pulses occurred was because every rotation of the neutron star causes energy to swipe past Earth exactly how light from a lighthouse sweeps light onto the oceans. Scientists first thought the pulses were from aliens until they proposed that the new star had to be denser than any type previously discovered, being the size of a planet but with the power of a star. Astronomers named these new stars “pulsars” and investigated continuously until 1 year later when they found a pulsar, burried deep within the remains of a super local, the pulsar known as the “Crab Pulsar” which is the closest pulsar to Earth. Interestingly, Swiss astronomer Fritz Zwicky had mathematically proven this phenomena 80 years prior but was labeled a hack for his wild theories

The Advent and Evolution of Noodles Within China

Leave a comment

The oldest known noodles ever discovered were found in China and date back 4000 years, discovered virtually fully preserved in a sealed bowl buried beneath sediment. These noodles were not made of wheat but rather from millet, which provides insight into early culinary traditions of the ancient world. These millet based noodles were distinct from future varieties which relied upon wheat, reflecting the grains available in ancient China during the period. This discovery demonstrates the early noodle making techniques which became refined over the coming centuries. By 400 B.C., noodles existed across Asia, likely produced by mixing flour and water into a dough. In comparison to the noodles from 400 B.C., which were likely produced using wheat or other grains and kneaded into dough, the 4000 year old noodles appeared to have been hand pulled and stretched into thin strands rather than being cut. By 400 B.C., more structured noodle cutting methods had emerged, allowing for different regional styles and preparations of noodles to develop (e.g. Lamian which is a hand pulled noodle still popular during the modern day, Dao Xiao Mian which is shaved directly from a block of dough, Biang Biang Mian which is known for its wide belt like shape etc.). These discoveries highlight not only the ingenuity of early civilizations but also the evolution of food production and technologies to produce said food. The shift from millet based noodles to flour based dough reflects advancements in milling, agricultural practices, and culinary techniques, demonstrating how food has continuously adapted over time to the resources available to local populations

The Reason Europeans Began Consuming Coffee During the 16th Century

Leave a comment

Coffee was initially referred to as a drink only consumed by the devil and frowned upon until Pope Clement VIII tried it and changed his opinion which changed Rome, Italy’s stance. Coffee was seen as the devil’s drink because it was the drink of the Muslim and therefore by default the infidels with whom Christians had been at war for centuries. Pope Clement VIII famously stated that coffee was so delicious that Christians should cheat the devil by baptizing the beverage

How Plants Produce Food Via Photosynthesis

Leave a comment

If a leaf is magnified 1000x, green bacteria like structures can be observed, referred to as “chloroplasts,” which are packed into virtually every cell of a plant. These chloroplasts behave like bacteria, retaining their own deoxyribonucleic acid, and are only 5000ths of 1 millimeter (0.005 millimeters or 5 micrometers) in diameter. It is inside chloroplasts that photosynthesis occurs. Photons, which are tiny and rapid moving particles of electromagnetic energy (e.g. rays of light), are harvested upon the surface of the plant’s leaves, where they then enter the plant’s cells and are absorbed by the light harvesting complex located within the chloroplasts themselves. It is here that the photon is leveraged to drive the photolysis reaction, which is to split a water molecule and release oxygen, electrons, and hydrogen ions, fueling the energy transfer mechanisms that ultimately convert carbon dioxide into sugars for the plant’s growth and survival

The Caribbean Village of Biological Males Born Without Male Genitalia

Leave a comment

There is a village in the Dominican Republic called Salinas, in which 1 in 90 of the people born are born as males, with testicles, but without a penis, because of misconstrued instructions at birth. In males, the gene on the Y chromosome, specifically the Sex Determining Region Y (SRY), instructs the gonads to become testicles. This leads to the creation of dihydrotestosterone which is a stronger version of testosterone. Dihydrotestosterone transforms the tubercle which all males and females have, into a penis. Females do not make dihydrotestosterone, therefore their gonads become ovaries, and the tubercle becomes a clitoris. Infants perceived as female at birth, due to a lack of dihydrotestosterone during fetal development, later develop a penis during puberty when testosterone triggers penile growth, as it does in typical male development. Those who lack the ability to create dihydrotestosterone, as is the case with those born as males but raised as females in the Caribbean village of Salinas, Dominican Republic where it is common, are technically male, but without a penis, a condition referred to as “5 alpha reductase deficiency”. This condition is quite well accepted in this part of the world and even has a term which is “guevedoce(s)”, (pronounced “guava-doh-chey”) which means “penis/testicles at 12” in Spanish. This condition whilst common in this region of the Caribbean, it is very rare in other parts of the world

How Armor Was Decorated During the Medieval Period

1 Comment

Armor was embroidered during the Medieval period by using oil and lead paint to mark off ornate areas which would stand out and perhaps be decorated with gold or other precious metals in a process referred to as “gilding”. Gold does not easily bind to any type of metal and the only way to properly do so is to undergo a process which involves mixing the gold with mercury. Once applied, a mixture of salt, vinegar, and copper sulphate, which is root killer, makes a paste which eats through the metal leaving the painted parts untouched, and resulting in an etched piece of armor. Blacksmiths sometimes heat treated armor which turned it a blueish hue which essentially rusts the metal as it is referred to as an “oxide” and an oxide occurs when a metal comes into contact with oxygen which reacts with the metal and creates a deposit when heated to a very specific temperature, as the heat is what shifts the red color of rust to the blue area of the color spectrum
