Aztec sun stone

Aztec is a term used to refer to certain ethnic groups of central Mexico, particularly those groups who spoke the Nahuatl language and who achieved political and military dominance over large parts of Mesoamerica in the 14th, 15th and 16th centuries, a period referred to as the Late post-Classic period in Mesoamerican chronology. Often the term "Aztec" refers exclusively to the people of Tenochtitlan, situated on an island in Lake Texcoco, who called themselves Mexica Tenochca or Colhua-Mexica. Sometimes it also includes the inhabitants of Tenochtitlan's two principal allied city-states, the Acolhuas of Texcoco and the Tepanecs of Tlacopan, who together with the Mexica formed the Aztec Triple Alliance which has also become known as the "Aztec Empire". In other contexts it may refer to all the various city states and their peoples, who shared large parts of their ethnic history as well as many important cultural traits with the Mexica, Acolhua and Tepanecs, and who like them, also spoke the Nahuatl language. In this meaning it is possible to talk about an Aztec civilization including all the particular cultural patterns common for the Nahuatl speaking peoples of the late postclassic period in Mesoamerica.




Fourth National Flag

The Flag of the United Mexican States or Mexico is a vertical tricolor of green, white, and red with the national coat of arms charged in the center of the white stripe. While the meaning of the colors has changed over time, these three colors were adopted by Mexico following independence from Spain during the country's War of Independence. The current flag was adopted in 1968, but the overall design has been used since 1821 when the First National Flag was created. The current law of national symbols, Law on the National Arms, Flag, and Anthem, that governs the use of the national flag has been in place since 1984. Throughout history, the flag has changed 4 times, as the design of the coat of arms and the length-width ratios of the flag have been modified. However, the coat of arms has had the same features throughout: an eagle, holding a serpent in its talon, is perched on top of a prickly pear cactus; the cactus is situated on a rock that rises above a lake. The coat of arms is derived from an Aztec legend that their gods told them to build a city where they spot an eagle and a serpent, which is now Mexico City.




Front page of the sheet music to the Mexican anthem

The National Anthem of Mexico (Spanish: Himno Nacional Mexicano) was officially adopted in 1943. The lyrics of the national anthem, which allude to Mexican victories in the heat of battle and cries of defending the homeland, were composed by poet Francisco González Bocanegra in 1853, after his fiancée locked him in a room. In 1854, Jaime Nunó arranged the music which now accompanies González's poem. The anthem, consisting of ten stanzas and a chorus, entered into use on September 16, 1854. From 1854 until its official adoption, the lyrics underwent several modifications due to political changes in the country. Unofficially, the anthem is sometimes called "Mexicanos, al grito de guerra" (Spanish for "Mexicans, at the cry of war") which is also the first line of the chorus.Officially since 1943, the full national anthem consists of the chorus, 1st stanza, 5th stanza, 6th stanza and 10th stanza.The modification of the lyrics was ordered by President Manuel Ávila Camacho in a decree printed in the Diario Oficial de la Federación.




Page 9 of the Dresden Codex showing the classic Maya language written in Mayan hieroglyphs (from the 1880 Förstermann edition)

The Mayan languages (alternatively: Maya languages) form a language family spoken in Mesoamerica and northern Central America. Mayan languages are spoken by at least 6 million indigenous Maya, primarily in Guatemala, Mexico, and Belize. In 1996, Guatemala formally recognized 21 Mayan languages by name,and Mexico recognizes eight more.The Mayan language family is one of the best documented and most studied in the Americas.Modern Mayan languages descend from Proto-Mayan, a language thought to have been spoken at least 5,000 years ago; it has been partially reconstructed using the comparative method.Mayan languages form part of the Mesoamerican Linguistic Area, an area of linguistic convergence developed throughout millennia of interaction between the peoples of Mesoamerica. All Mayan languages display the basic diagnostic traits of this linguistic area. For example, all use relational nouns instead of prepositions to indicate spatial relationships.




An image of Our Lady of Guadalupe

Our Lady of Guadalupe, also called the Virgin of Guadalupe (Spanish: Nuestra Señora de Guadalupe or Virgen de Guadalupe) is a 16th century Roman Catholic icon depicting an apparition of the Virgin Mary. It is Mexico's most beloved religious and cultural image. Our Lady of Guadalupe is known in Mexico as "La Virgen Morena", which means "The brown-skinned Virgin". Our Lady of Guadalupe's feast day is celebrated on December 12, commemorating the account of her appearances to Juan Diego on the hill of Tepeyac near Mexico City from December 9 through December 12, 1531.The Virgin of Guadalupe is a cultural symbol of significant importance to the Mexican identity.Some historians consider that the icon was meant to syncretically represent both the Virgin Mary and the indigenous Mexican goddess Tonantzin, providing a way for 16th century Spaniards to gain converts among the indigenous population of early Mexico. It may have provided a method for 16th century indigenous Mexicans to covertly practice their native religion, although the contrary was asserted in the canonization process of Juan Diego.




Radar topography reveals the 180 kilometer (112 mi) ring of the crater; clustered around the crater's trough are numerous sinkholes, suggesting a prehistoric oceanic basin in the depression left by the impact (Image courtesy NASA/JPL-Caltech).

The Chicxulub Crater (IPA[tʃikʃuˈlub]) is an ancient impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located near the town of Chicxulub, after which the crater is named—as well as the possible literal translation of the name, "the tail of the devil."The crater is more than 180 kilometers (110 mi) in diameter, making the feature one of the largest confirmed impact structures in the world; the impacting bolide (asteroid or comet) that formed the crater was at least 10 km (6 mi) in diameter. The crater was discovered by Glen Penfield, a geophysicist who had been working in the Yucatán while looking for oil during the late 1970s. Evidence for the impact origin of the crater includes shocked quartz, a gravity anomaly, and tektites in surrounding areas. The age of the rocks and isotope analysis show that this impact structure dates from the end of the Cretaceous Period, roughly 65 million years ago.





In habitat in Oaxaca

Pinguicula moranensis (pronounced /pɪŋˈɡwɪkjʊlə ˌmɒrəˈnɛnsɪs/) is a perennial rosette-forming insectivorous herb native to Mexico and Guatemala. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 10 centimeters (4 in) long, which are covered in mucilagenous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single pink, purple, or violet flowers appear twice a year on upright stalks up to 25 centimeters long. The species was first collected by Humboldt and Bonpland on the outskirts of Mina de Morán in the Sierra de Pachuca of the modern-day Mexican state of Hidalgo on their Latin American expedition of 1799–1804.





Hurricane Ismael off the coast of Baja California

Hurricane Ismael was a weak Pacific hurricane that killed over one hundred people in northern Mexico in September of the 1995 Pacific hurricane season. It developed from a persistent area of deep convection on September 12, and steadily strengthened as it moved to the north-northwest. Ismael attained hurricane status on September 14 while located 210 miles (340 km) off the coast of Mexico. It continued to the north, and after passing a short distance east of Baja California it made landfall on Topolobampo in the state of Sinaloa with winds of 80 mph (130 km/h). Ismael rapidly weakened over land, and dissipated on September 16 over northwestern Mexico. The remnants entered the United States and extended eastward into the Mid-Atlantic States.Offshore, Ismael produced waves of up to 30 feet (9 m) in height. Hundreds of fishermen were unprepared by the hurricane, which was expected to move more slowly, and as a result 52 ships were wrecked, killing 57 fishermen. The hurricane destroyed thousands of houses, leaving 30,000 people homeless.




Hurricane Lane, as seen from TERRA MODIS

Hurricane Lane was the strongest Pacific hurricane to make landfall in Mexico since Hurricane Kenna of 2002. The thirteenth named storm, ninth hurricane, and sixth major hurricane of the 2006 Pacific hurricane season, Lane developed from a tropical wave on September 13 to the south of Mexico. It moved northwestward parallel to the coast of Mexico, and steadily intensified in an area conducive to further strengthening. After turning to the northeast, Lane attained peak winds of 125 mph (205 km/h), and made landfall in the Mexican state of Sinaloa at peak strength. It rapidly weakened and dissipated on September 17, and later brought precipitation to southern Texas.Throughout its path, Lane resulted in four deaths and moderate damage. Damage was heaviest in Sinaloa where the hurricane made landfall, including reports of severe crop damage. Across Mexico, an estimated 4,320 homes were impacted by the hurricane, with about 248,000 people affected. Moderate flooding was reported in Acapulco, resulting in mudslides in some areas. Damage across the country totaled $2.2 billion (2006 MXN, $203 million (2006 USD).




Female (left) and male (right) Cochineals

Cochineal is the name of both crimson or carmine dye and the cochineal insect (Dactylopius coccus), a scale insect in the suborder Sternorrhyncha, from which the dye is derived. There are other species in the genus Dactylopius which can be used to produce cochineal extract, but they are extremely difficult to distinguish from D. coccus, even for expert taxonomists, and the latter scientific name (and the use of the term "cochineal insect") is therefore commonly used when one is actually referring to other biological species; suffice it to say that the reader should be aware that there is more than one cochineal insect. The primary biological distinctions between species are minor differences in host plant preferences, in addition to very different geographic distributions. D. coccus itself is native to tropical and subtropical South America and Mexico.This type of insect, a primarily sessile parasite, lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid which deters predation by other insects. Carminic acid can be extracted from the insect's body and eggs to make the dye. Cochineal is primarily used as a food colouring and for cosmetics.
