[6] The area was the settled homeland of the ancient Mesoamerican Zapotec civilization going back at least 2500 years, with the oldest archeological finds being in the Valley of Oaxaca.San Bartolo refers to the patron saint, Bartholomew and Coyotepec is from Nahuatl meaning "hill of coyotes".[4][9] The techniques for making the pottery have changed little during these centuries, with plates serving as potters’ wheels and design remaining traditional.Doña Rosa discovered that by polishing the nearly dry clay before firing, the gray color turned to a shiny black.[2] The center of the town is similar to that of the city of Oaxaca, with a main plaza, parish church and municipal palace.[10] The museum's roots extend to 1905, when local resident Manuel Guzmán donated land for the establishment of a cultural center.In that year, it sponsored, along with ARIPO - Artesanías e Industrias Populares del estado de Oaxaca, the first crafts competition.The museum has held temporary exhibits such as "Mujeres tejiendo historias" (Women knitting stories), "Grandes Maestros del Arte Popular de Oaxaca" (Grand Masters of Popular Art in Oaxaca) and "Historia y evolución del barro negro" (History and evolution of barro negro pottery).[5][11] The museum offers guided tours in Spanish and English, workshops for adults and children, and spaces to rent for events.[14] Two pottery pieces which are indicative of San Bartolo are the traditional Cantaro, a large jar which can be used for liquid storage or as a musical instrument and the "chango mezcalero" or mezcal monkey.This is a clay container in the shape of a monkey to hold mezcal, Oaxaca main distilled spirit, which has become a collectable folk art item.The family believes that Doña Rosa's husband, Juventino Nieto, invented the design at the request of cantina operators from the city of Oaxaca.In that same year, he created a mural in barro negro at the Baseball Academy in San Bartolo Coyotepec sponsored by the Alfredo Harp Helú Foundation.[2] Agriculture employ about 19% of the population growing vegetables such as corn, beans and squash blossom, as well as decorative flowers such as daisies, Mexican marigolds and poinsettias.However, the people here still called him "Padre" (Father) and he continues to live in the house that has been traditionally reserved for parish priests with his wife and two children.[17] Beginning in 2004, Marinero began to publicly support gay marriage as well[18] In 2009 the Academy of Baseball was founded in San Bartolo Coyotepec by Alfredo Harp Helú.The facilities cover more than ten hectares and include a library, computer center, three baseball fields, and living quarters for students.
