What is Tyrian purple? Origin and etymology

Tyrian purple is a color derived from a dye made from the secretion of the purple gland (hypogillary gland) of snails belonging to the family Muricidae. This secretion changes from colorless to yellow, green, blue, and then purple upon contact with air and subsequent oxidation. This phenomenon is due to a photochemical reaction, and the beautiful purple color is obtained through a very complex process. Only a small amount of dye can be extracted from a single snail, and due to its rarity, it has been treated as an expensive dye since ancient times.

The historical background of the color Tyrian purple

The history of Tyrian purple is ancient, believed to have originated in Phoenicia around 1600 BC. This technique flourished along the Mediterranean coast, with Tyre-produced purple being considered the finest and known as "Tyrian purple" or "royal purple." In the Roman Empire, it became a color that only a select few privileged classes, such as emperors and senators, were permitted to wear, and it was a symbol of authority.

In Japan, descriptions of purple dye can be found as far back as the "Records of Wei: Account of the Wa People," but the most reliable artifacts include the "Purple Ground Phoenix-Shaped Brocade" among the treasures of the Shōsōin. However, ancient Japanese purple dye mainly came from the roots of the gromwell plant, and there is debate as to whether Tyrian purple dye was used on a large scale. It is known that Tyrian purple dye is still used in some of the ceremonial garments used in the Shikinen Sengu (periodic rebuilding) of Ise Grand Shrine.

Related literature, waka poetry, and seasonal words

Due to its rarity and noble nature, Tyrian purple is sometimes depicted as a special color in literary works. However, instances where "Tyrian purple" is explicitly mentioned in classical Japanese literature are fewer than instances where "purple" dyed from gromwell is used. This is thought to be because plant-based dyes were the mainstream for purple dyeing in Japan. Although it does not directly exist as a seasonal word, its noble hue is sometimes associated with elegant scenes.

FAQ

❓ What is the difference between purple dyed with Tyrian purple and purple dyed with gromwell?
While Tyrian purple is an animal-based dye (from the secretions of snails), the purple from gromwell is a plant-based dye (from the roots of the gromwell plant). Tyrian purple develops its color in sunlight and is resistant to fading, but gromwell purple develops its color in alkaline conditions and is sensitive to light and acid. In terms of hue, Tyrian purple tends to have a stronger reddish tint, while gromwell purple tends to have a stronger bluish tint.
❓ Why is the color of Tyrian purple called "Imperial Purple"?
In the ancient Roman Empire, wearing cloth dyed with Tyrian purple was limited to a select few privileged classes, such as emperors and the highest-ranking clergy. Due to its rarity and high production cost, it became a symbol of authority and came to be known as "royal purple."
❓ Is dyeing with Tyrian purple still practiced today?
Yes, it is practiced. However, because the raw material, shellfish, is difficult to collect and the dyeing process is complex, it is extremely rare and expensive. In Japan, it is passed down as a traditional technique, such as dyeing some of the ceremonial garments used in the Shikinen Sengu (periodic rebuilding) of Ise Grand Shrine. In addition, some workshops produce and sell it as a craft.
