Maya scholars owe a lot to a determined Englishwoman named Adela Catherine Breton. In 1900 she rode into the ruins of Chichen Itza where she spent the next eight years sketching and painting the fading murals and reliefs. Today her record is all that remains of many of those invaluable works of art. Other artists are now making similar copies of the last originals before they, too, are obliterated.
