The dye substance is a mucous secretion from the hypobranchial gland of one of several species of medium-sized predatory sea snails that are found in the eastern Mediterranean Sea, and off the Atlantic coast of Morocco. Two shells of Bolinus brandaris, the spiny dye-murex, a source of the dye Another dye extracted from a related sea snail, Hexaplex trunculus, produced a blue colour after light exposure which could be the one known as tekhelet ( תְּכֵלֶת), used in garments worn for ritual purposes. Some speculate that the dye extracted from the Bolinus brandaris is known as argaman ( ארגמן) in Biblical Hebrew. Later (9th century) a child born to a reigning emperor was said to be porphyrogenitos, 'born in the purple'. The production of Tyrian purple was tightly controlled in the succeeding Byzantine Empire and subsidized by the imperial court, which restricted its use for the colouring of imperial silks. the phrase 'donned the purple' means 'became emperor'). As a result, 'purple' is sometimes used as a metonym for the office (e.g. īy the fourth century CE, sumptuary laws in Rome had been tightened so much that only the Roman emperor was permitted to wear Tyrian purple. The even more sumptuous toga picta, solid Tyrian purple with a gold stripe, was worn by generals celebrating a Roman triumph. The most senior Roman magistrates wore a toga praetexta, a white toga edged with a stripe of Tyrian purple. The expense meant that purple-dyed textiles became status symbols, whose use was restricted by sumptuary laws. īecause it was extremely difficult to make, Tyrian purple was expensive: the 4th century BCE historian Theopompus reported, 'Purple for dyes fetched its weight in silver at Colophon' in Asia Minor. It came in various shades, the most prized being that of black-tinted clotted blood. The dye was greatly prized in antiquity because the colour did not easily fade, but instead became brighter with weathering and sunlight. It has been suggested that the name Phoenicia itself means 'land of purple'. Tyrian purple may first have been used by the ancient Phoenicians as early as 1570 BCE. The pigment was expensive and complex to produce, and items colored with it became associated with power and wealth. Production of Tyrian purple for use as a fabric dye began as early as 1200 BCE by the Phoenicians, and was continued by the Greeks and Romans until 1453 CE, with the fall of Constantinople. Tyrian purple is a pigment made from the mucus of several species of Murex snail.

In the foreground, two Roman magistrates are identified by their toga praetexta, white with a stripe of Tyrian purple.īiological pigments were often difficult to acquire, and the details of their production were kept secret by the manufacturers. Caesar, riding in the chariot, wears the solid Tyrian purple toga picta. A twentieth-century depiction of a Roman triumph celebrated by Julius Caesar.
