Alexander (the Great, to identify him properly from all the other Alexanders I have known, my ex-boss Lindsay among them), well he and the Roman emperors displayed a penchant for Tyrian purple
. The Romans used Tyrian purple
to prove that class distinction existed.
Marine gastropods of the family Muricidae produce Tyrian purple
(6,6'-dibromoindigo; Cooksey 2001), a dye of significant historical importance that can be obtained from no other natural source (Westley & Benkendorff 2008).
By 1857, Perkin's factory was producing "Tyrian Purple
" for sale to commercial silk dyers and he was working on new dyes for wool and cotton (1).
- the original hue - is believed to have been discovered as long ago as 4,000 years, during the Minoan civilisation.
This dates back to the Roman times, when clothing was died with Tyrian purple
(produced from the mucus of the hypobranchial gland of various species of marine mollusks, notably Murex) and limited to the upper class.
The resultant dye varies from violet to dark, blood red and was known in the Levantas Tyrian purple
after the production site at the city of Tyre on the eastern Mediterranean.
A colour by virtue of its rarity or difficulty of production (Tyrian purple
, Iznik red, lapis lazuli) can have the status of a precious material and be used accordingly.
One was Tyrian purple
, obtained from a snail in the harbor of Tyre, a dye so expensive it was reserved in late Roman times for royalty.
The award's name was a tribute to the murex seashell, which produces the Tyrian purple
dye, widely used during Phoenician times.
ABSTRACT The intertidal purple snail Plicopurpura pansa was intensively exploited for "Tyrian Purple
," leading to declining populations and prohibition by the Mexican government of commercial exploitation.
so that the color was called Tyrian purple
. Between the difficulty of amassing a quantity of it, and its great desirability, its price went sky-high, but it still sold, albeit only to the rich and powerful.
These develop enzymatically in light and oxygen into a purple pigment known as "Tyrian Purple
," Royal Purple" or "Shellfish Purple." Fretter and Graham (1994) considered the main function of the hypobranchial gland to be a secretor of mucus for trapping and cementing particulate matter sucked into the mantle cavity with the respiratory water current prior to its expulsion.
pansa to obtain "Tyrian Purple
" and to collect the snails as a bait for fishery or as a special food for foreigners should be enforced and should be extended to the removal the snails from the crevices of intertidal rocks.
In pre-Roman and Roman times "Tyrian purple
" from the Mediterranean muricids Murex trunculus, M.
ABSTRACT Most marine snails of the families Muricidae and Thaididae produce in their hypobranchial gland (mucus gland) a colorless secretion containing minute amounts of chromogens, which develop under the influence of light and oxygen into a pigment known as "Tyrian Purple
." The hypobranchial gland of Plicopurpura pansa (Gould, 1853) is an exception among the muricids, because it is so active the snails can be stimulated periodically to expulse the secretion without harming the animals.
