- McCrone discovered that the Vinland Map, purporting to show that Leif Ericson had visited America some five centuries before Columbus, had traces of anatase, a pigment not synthesized until about 1920.

Origin
Early 19th century: from French, from Greek anatasis 'extension', with allusion to the length of the crystals.
