Photographed in 1971, in Mexico, this is the famous Pyramid of the Sun – the largest building at the Teotihuacan complex on the Avenue of the Dead. A sacrificial altar and temple are thought to have once existed on the top. It was constructed in about 100AD and is the third largest pyramid in the world, although not nearly one of the tallest. Much of the outer plaster as well as artifacts did not survive to be studied by Archeologists as they either weathered away or were looted. I have a liking for very blurred photographs because of the way they emphasize form, light and pattern. This person’s camera focused on a row of stones at the very bottom, leaving the impressive slope of stairs as a bright and tantalizing blur.
