Teotihuacan – also written Teotihuacán, with a Spanish orthographic accent on the last syllable – is an enormous archaeological site in the Basin of Mexico, just 30 miles (48 km) northeast of Mexico City, containing some of the largest pyramidal structures built in the pre-Columbian Americas. Apart from the pyramidal structures, Teotihuacan is also known for its large residential complexes, the Avenue of the Dead, and numerous colorful, well-preserved murals. Additionally, Teotihuacan produced a thin orange pottery style that spread through Mesoamerica.

The city is thought to have been established around 100 BC and continued to be built until about 250 AD. The city may have lasted until sometime between the 7th and 8th centuries AD. At its zenith, perhaps in the first half of the 1st millennium AD, Teotihuacan was the largest city in the pre-Columbian Americas, with a population of perhaps 125,000 or more, placing it among the largest cities of the world in this period. Teotihuacan began as a new religious center in the Mexican Highland around the first century AD. This city came to be the largest and most populated center in the New World. Teotihuacan was even home to multi-floor apartment compounds built to accommodate this large population. The civilization and cultural complex associated with the site is also referred to as Teotihuacan or Teotihuacano.

Juan Villoro (Mexico City, 1956) is a Mexican writer and journalist. He has been well known among intellectual circles in Mexico, Latin America and Spain for years, but his success among the readers grew since receiving the Herralde Prize for his novel El testigo.

Juan Villoro received his bachelor's degree in sociology from the Metropolitan Autonomous University, Iztapalapa campus. As a rock music fan, he was the DJ for the radio program "El lado oscuro de la luna" (the Spanish translation of The Dark Side of the Moon by Pink Floyd) from 1977 until 1981. He was then made the cultural attaché to Berlin in the then German Democratic Republic.

For three decades, Villoro has produced a steady output of articles for various Mexican periodicals, concentrating in such areas as sports, rock, cinema, literature and travel. Palmeras de la brisa rapida: un viaje a Yucatán ("Palm Trees of the Rapid Breeze: A Journey to Yucatan") 1989 is an account of his travels in a part of Mexico known for its Mayan culture. His first novel was El disparo de argón ("The Shot of Argon"), published in 1991. Los once de la tribu ("The Eleven of the Tribe"), published in 1995, collects many of his best short, non-fiction essays and interviews. The title refers to the number of people on an international football team. He covers a wide range of topics, including Andy Warhol, the Rolling Stones, the television series Dallas, the absurdities of publishing children's literature in the United States and an interview with Jane Fonda.
