Murex is the name of a family of sea snails that led to the Phoenicians controlling the very lucrative trade in purple dyed silk(b). Some have attributed the origin of the name ‘Phoenicia’ to a Greek word meaning ‘purple’.
The dye had been extracted from the Murex snails and the resulting cloth was considered highly desirable to such an extent that in later years the colour was reserved for members of the Roman imperial family. It took 10,000 snails to produce one gram of dye, making it extremely expensive. Unfortunately, the downside is that this purple dye stank badly.
Demand for this exclusive dye persisted for nearly 3,000 years. Purple was also the preserve of cardinals in the Roman Catholic Church, equating them with kings, until the 15th century when red was decreed for them, a situation that still pertains.
There is some suggestion that the Phoenicians were not the first to develop this process following the discovery of mounds of Murex shells on Crete dated to the early 2nd millennium BC. It is also claimed that the Italians of the same period also knew of the procedure(g) .
Over a century ago James Baikie noted that “the dyeing of robes with the renowned ‘Tyrian purple,’ must be denied to them and claimed for the Minoans. In 1903, Messrs. Bosanquet and Currelly found on the island of Kouphonisi (Leuke), off the south-east coast of Crete, a bank of the pounded shell of the murex from which the purple dye was obtained, associated with pottery of the Middle Minoan period; and in 1904 they discovered at Palaikastro two similar purple shell deposits, in either case associated with pottery of the same date.”
It is difficult not to see a possible link between murex dye developed by the Phoenicians and the biblical injunction to Jews of the same region to wear blue (tekhelet) tassels (tzitziyots) from the corners of four-cornered garments. Recently, near the caves of the Dead Sea Scrolls a rare 2,000-year-old fragment of cloth was discovered(c) that had been treated with the Murex dye.
Michael Hübner pointed out that that apart from Murex, Northwest Africa and the Canaries were home to the Indigo plant and Orseille lichen, which both can be used to produce blue dyes(h).
Frank Joseph notes that Berber village elders even today wear special dark blue robes when meeting in council. This is seen as an echo of the custom of the kings of Atlantis as recorded by Plato Critias (120b-c).
A similar purple dyeing process was discovered in Central America(a) adding to the suggestion of pre-Colombian contacts between Europe and the Americas. In September 2016, it was announced(e) that “a George Washington University researcher has identified a 6,200-year-old indigo-blue fabric from Huaca, Peru, making it one of the oldest-known cotton textiles in the world and the oldest known textile decorated with indigo blue.” Unfortunately, the source of the dye was not identified. Even today, in Oaxaca, Mexico, shellfish dyeing is still carried on, but using the milky liquid from the purpura patula, a marine mollusk(f), unlike the murex mollusk which is killed in the process of obtaining the ink, the purpura have always been milked alive and left to replenish their dye fluid for harvesting at another time. If there was a dyeing link between the Americas and the Mediterranean. in which direction did it initially travel?
Pliny the Elder noted that Uba, a Numidian king, intended to establish Murex farming on the Hesperides located 12,000 km from Cadiz. This comment has been linked with a mention by Diodorus Siculus regarding a large island know to the Phoenicians outside the Pillars of Heracles. Advocates of an Atlantic location for Atlantis have seized upon these two references, although the linkage is somewhat tenuous.
There is an extensive online article(d) on the history and use of ‘Tyrian Purple’.
*A few years ago the BBC published a short piece(i) on the chemistry behind the Tyrian Purple. In August 2018 they returned to the subject with a more extensive article(j) outlining the mythology and history associated with the dye.*
