From the secretion of a gland of the purple snail can be obtained purple dye. In the sunlgiht, the colorless secretion first turns green, then blue and then purplish and scarlet. Already in the 1st millennium BC, the Phoenicians used purple snails to dye. Roman magistrates and senators wore their togas with a purple stripe and also the togas of the Roman emperors were colored with purple. Since the amount of secretion of a snail is very low, you needed about 10,000 purple snails for 1 kg of wool. Purple snails were imported to Carnuntum for further processing. 7,4 x 4,9 cm
