"The head of the largest bird is made of
segments of circles, whose radii vary between 32
and 66 feet. The figure is much stylized,
showing in profile, while two circles of equal
diameter could represent two eyes. The two
curves continuing from the end of the neck have
exactly the same radius, being both concentrical
to the eyes." Maria Reiche, Mystery on the
desert.
