	Welcome to my web Page
	For the past 40 years I have been studing Mexican History in particular the XVI Century,  where I have been tracing the Artistic Indigenous work during Spanish Colony.
	After years of research in this area I have started revisiting  many  Prehispanic Sources  in  particular the works of Fray Toribio de Benavente Motolinía and Fray Bernardino de Sahagún.
	My background in Chemistry helped me to  Decipher the Maya Blue pigment the elusive and beautiful pigment developed by one of the most fascinating civilisations of the world.
	Using microscopic imaging I discovered the ingredients and production process of the pigment. The most important is a special clay palygorskite.   Chapman mentioned the organic compound and Van Olphen discovered palygorskite but I synthesized from añil leaves.
	Another of my passions is the Medieval and Colonial Christian Iconography in particular XVI Century in New Spain (Mexico) and Romanic and Gothic periods in Europe.
	My latest work has come from different collaboration with several Chemists and physicists, Dr Giaccomo Chiari and Dr David Ajò, from the University of Turin, and Dr Manuel Sánchez del Rio from the ESRF in France. Together we are conducting Spectral Analysis of Maya Blue Pigment.
	I am Emeritus Professor of the INAH - Instituto Nacional de Antropología e Historia in México. The  interview for this ocassion resumes much of my Life: Constantino Reyes-Valerio, a life full of wisdom
CONACYT	I am part of the Sistema Nacional de Investigadores (SNI-CONACYT), a research council established by the Mexican Government to promote Scientific Research.
	In  1972  I was a Fellow of the John Simon Guggenheim Memorial Foundation.
