Note 313 — Chapter V
Reading edition
The Cretan tincture was extracted from a plant which Theophrastus, Dioscorides, and Pliny respectively name. The last calls it the Phycos thalassion. This was not a sea-weed, but a lichen—probably the same from which the orchid purple of modern art is prepared. See Birdwood, “Indian Arts,” i. p. 238.
