Aztec dreadlocks?

Tentatively removed:

Dreadlocks were also part of Mexican culture. In a description of an Aztec ritual, Historian William Hickling Prescott referred to dreadlocked Priests of the Aztec civilization, a Mesoamerican people of central Mexico in the 14th, 15th and 16th century. "On the summit he was received by six priests, whose long and matted locks flowed disorderly over their sable robes, covered with hieroglyphic scrolls of mystic import. They led him to the sacrificial stone, a huge block of jasper, with its upper surface somewhat convex." (William H. Prescott, History of the Conquest of Mexico)

The Aztecs may, indeed, have worn dreadlocks.  However, the quote provided refers to only "matted locks," which certainly are not the same as dreads.  A bad case of "bed-head" is not dreadlocks.  I've searched the Internet for "Aztec dreadlocks" and came up with zilch.  Please, please provide definitive information before reinserting this unsubstantiated, and subwhat dubious, information.  Thanks.
