A trefoil is a graphic form composed of the outline of three overlapping rings, used in architecture, Pagan and Christian symbolism, among other areas. The term is also applied to other symbols with a threefold shape. A similar shape with four rings is called a quatrefoil.
The Olmecs were the earliest known major Mesoamerican civilization, flourishing in the modern-day Mexican states of Veracruz and Tabasco from roughly 1200 to 400 BCE during Mesoamerica's formative period. They were initially centered at the site of their development in San Lorenzo Tenochtitlán, but moved to La Venta in the 10th century BCE following the decline of San Lorenzo. The Olmecs disappeared mysteriously in the 4th century BCE, leaving the region sparsely populated until the 19th century.
Filippo di ser Brunellesco di Lippo Lapi, commonly known as Filippo Brunelleschi and also nicknamed Pippo by Leon Battista Alberti, was an Italian architect, designer, goldsmith and sculptor. He is considered to be a founding father of Renaissance architecture. He is recognized as the first modern engineer, planner, and sole construction supervisor. In 1421, Brunelleschi became the first person to receive a patent in the Western world. He is most famous for designing the dome of the Florence Cathedral, and for the mathematical technique of linear perspective in art which governed pictorial depictions of space until the late 19th century and influenced the rise of modern science. His accomplishments also include other architectural works, sculpture, mathematics, engineering, and ship design. Most surviving works can be found in Florence.
Lorenzo Ghiberti, born Lorenzo di Bartolo, was an Italian Renaissance sculptor from Florence, a key figure in the Early Renaissance, best known as the creator of two sets of bronze doors of the Florence Baptistery, the later one called by Michelangelo the Gates of Paradise. Trained as a goldsmith and sculptor, he established an important workshop for sculpture in metal. His book of Commentarii contains important writing on art, as well as what may be the earliest surviving autobiography by any artist.
Florence Cathedral, formally the Cathedral of Saint Mary of the Flower, is the cathedral of the Catholic Archdiocese of Florence. Commenced in 1296 in the Gothic style to a design of Arnolfo di Cambio and structurally completed by 1436 with the dome engineered by Filippo Brunelleschi; the basilica's exterior is faced with polychrome marble panels in various shades of green and pink, bordered by white, and features an elaborate 19th-century Gothic Revival (west) façade by Emilio De Fabris.
In knot theory, a branch of mathematics, the trefoil knot is the simplest example of a nontrivial knot. The trefoil can be obtained by joining the two loose ends of a common overhand knot, resulting in a knotted loop. As the simplest knot, the trefoil is fundamental to the study of mathematical knot theory.
The Florence Baptistery, also known as the Baptistery of Saint John, is a religious building in Florence, Italy. Dedicated to the patron saint of the city, John the Baptist, it has been a focus of religious, civic, and artistic life since its completion. The octagonal baptistery stands in both the Piazza del Duomo and the Piazza San Giovanni, between Florence Cathedral and the Archbishop's Palace.
El Perú, is a pre-Columbian Maya archeological site occupied during the Preclassic and Classic cultural chronology periods. The site was the capital of a Maya city-state and is located near the banks of the San Pedro River in the Department of Petén of northern Guatemala. El Perú is 60 km (37 mi) west of Tikal.
Tak'alik Ab'aj is a pre-Columbian archaeological site in Guatemala. It was formerly known as Abaj Takalik; its ancient name may have been Kooja. It is one of several Mesoamerican sites with both Olmec and Maya features. The site flourished in the Preclassic and Classic periods, from the 9th century BC through to at least the 10th century AD, and was an important centre of commerce, trading with Kaminaljuyu and Chocolá. Investigations have revealed that it is one of the largest sites with sculptured monuments on the Pacific coastal plain. Olmec-style sculptures include a possible colossal head, petroglyphs and others. The site has one of the greatest concentrations of Olmec-style sculpture outside of the Gulf of Mexico, and was made a World Heritage Site in 2023 because of its long history of occupation.
Michelozzo di Bartolomeo Michelozzi, known mononymously as Michelozzo, was an Italian architect and sculptor. Considered one of the great pioneers of architecture during the Renaissance, Michelozzo was a favored Medici architect who was extensively employed by Cosimo de' Medici. He was a pupil of Lorenzo Ghiberti in his early years, and later collaborated with Donatello.
Teopantecuanitlan is an archaeological site in the Mexican state of Guerrero that represents an unexpectedly early development of complex society for the region. The site dates to the Early to Middle Formative Periods, with the archaeological evidence indicating that some kind of connection existed between Teopantecuanitlan and the Olmec heartland of the Gulf Coast. Prior to the discovery of Teopantecuanitlan in the early 1980s, little was known about the region's sociocultural development and organization during the Formative period.
Chalcatzingo is a Mesoamerican archaeological site in the Valley of Morelos dating from the Formative Period of Mesoamerican chronology. The site is well known for its extensive array of Olmec-style monumental art and iconography. Located in the southern portion of the Central Highlands of Mexico, Chalcatzingo is estimated to have been settled as early as 1500 BCE. The inhabitants began to produce and display Olmec-style art and architecture around 900 BCE. At its height between 700 BCE and 500 BCE, Chalcatzingo's population is estimated at between five hundred and a thousand people. By 500 BCE it had gone into decline. The climate in Morelos is generally warmer and more humid than the rest of the Highlands. The Chalcatzingo center covers roughly 100 acres (0.40 km2). Evidence indicates that this was a site of ritual significance.
Izapa is a very large pre-Columbian archaeological site located in the Mexican state of Chiapas; it is best known for its occupation during the Late Formative period. The site is situated on the Izapa River, a tributary of the Suchiate River, near the base of the volcano Tacaná, the sixth tallest mountain in Mexico.
Mesoamerica, along with Mesopotamia and China, is one of three known places in the world where writing is thought to have developed independently. Mesoamerican scripts deciphered to date are a combination of logographic and syllabic systems. They are often called hieroglyphs due to the iconic shapes of many of the glyphs, a pattern superficially similar to Egyptian hieroglyphs. Fifteen distinct writing systems have been identified in pre-Columbian Mesoamerica, many from a single inscription. The limits of archaeological dating methods make it difficult to establish which was the earliest and hence the progenitor from which the others developed. The best documented and deciphered Mesoamerican writing system, and the most widely known, is the classic Maya script. Earlier scripts with poorer and varying levels of decipherment include the Olmec hieroglyphs, the Zapotec script, and the Isthmian script, all of which date back to the 1st millennium BC. An extensive Mesoamerican literature has been conserved, partly in indigenous scripts and partly in postconquest transcriptions in the Latin script.

A trefoil is a graphic form composed of three leaves or lobes.
The Southern Maya Area is a region of Pre-Columbian sites in Mesoamerica. It is long believed important to the rise of Maya civilization, during the period that is known as Preclassic. It lies within a broad arc going southeast from Chiapa de Corzo in Mexico to Copán and Chalchuapa, in Central America.
A foil is an architectural device based on a symmetrical rendering of leaf shapes, defined by overlapping circles of the same diameter that produce a series of cusps to make a lobe. Typically, the number of cusps can be three (trefoil), four (quatrefoil), five (cinquefoil), or a larger number (multifoil). The word comes from Latin folium which meaning “leaf.”
Regional communications in ancient Mesoamerica are believed to have been extensive. There were various trade routes attested since prehistoric times. In this article, especially the routes starting in the Mexico Central Plateau, and going down to the Pacific coast will be considered. These contacts then went on as far as Central America.
The North Doors of the Florence Baptistery were made by Lorenzo Ghiberti between 1403 and 1424 and represent his first masterpiece, before the celebrated Gates of Paradise. The work is signed in the center, above the panels of the Nativity and the Adoration of the Magi: “OPVS LAUREN/TII•FLOREN/TINI.” After restoration in 2013-2015 the doors were displayed in the new Museo dell'Opera del Duomo and replaced by a copy.
