Note 71 — Chapter IX
Reading edition
In England there is a cockle called the purple, from the coloring matter it contains, believed to be one of the sources from which the celebrated Tyrian dye was obtained. The discovery is attributed in mythical story to a dog. The Tyrian Hercules was one day walking with his sweetheart by the shore, followed by her lap-dog, when the animal seized a shell just cast upon the beach. Its lips were stained with the beautiful purple flowing from the shell, and its mistress, charmed with the color, demanded a dress dyed with it of her lover.
