Dresden CodexThe Dresden Codex is a Maya book, which was believed to be the oldest surviving book written in the Americas, dating to the 11th or 12th century. However, in September 2018 it was proven that the Maya Codex of Mexico, previously known as the Grolier Codex, is, in fact, older by about a century. The codex was rediscovered in the city of Dresden, Germany, hence the book's present name. It is located in the museum of the Saxon State Library.
AmateAmate (amate aˈmate from āmatl ˈaːmat͡ɬ) is a type of bark paper that has been manufactured in Mexico since the precontact times. It was used primarily to create codices. Amate paper was extensively produced and used for both communication, records, and ritual during the Triple Alliance; however, after the Spanish conquest, its production was mostly banned and replaced by European paper. Amate paper production never completely died, nor did the rituals associated with it.
Cypriot syllabaryThe Cypriot or Cypriote syllabary is a syllabic script used in Iron Age Cyprus, from about the 11th to the 4th centuries BCE, when it was replaced by the Greek alphabet. A pioneer of that change was King Evagoras of Salamis. It is descended from the Cypro-Minoan syllabary, in turn, a variant or derivative of Linear A. Most texts using the script are in the Arcadocypriot dialect of Greek, but also one bilingual (Greek and Eteocypriot) inscription was found in Amathus.
Heat mapA heat map (or heatmap) is a 2-dimensional data visualization technique that represents the magnitude of individual values within a dataset as a color. The variation in color may be by hue or intensity. "Heat map" is a relatively new term, but the practice of shading matrices has existed for over a century. Heat maps originated in 2D displays of the values in a data matrix. Larger values were represented by small dark gray or black squares (pixels) and smaller values by lighter squares.
YaxhaYaxha (or Yaxhá in Spanish orthography) is a Mesoamerican archaeological site in the northeast of the Petén Basin region, and a former ceremonial centre and city of the pre-Columbian Maya civilization. Yaxha was the third largest city in the region and experienced its maximum power during the Early Classic period (c. AD 250–600). The city was located on a ridge overlooking Lake Yaxha. The name of the city derives from the Mayan for "blue-green water"; it is a notable survival of a Classic period place-name into the modern day.
Phaistos DiscThe Phaistos Disc (also spelled Phaistos Disk, Phaestos Disc) is a disk of fired clay from the Minoan palace of Phaistos on the island of Crete, possibly dating to the middle or late Minoan Bronze Age (second millennium BC). The disk is about in diameter and covered on both sides with a spiral of stamped symbols. Its purpose and its original place of manufacture remain disputed. It is now on display at the archaeological museum of Heraklion.
TikalTikal (tiˈkɑːl) (Tik’al in modern Mayan orthography) is the ruin of an ancient city, which was likely to have been called Yax Mutal, found in a rainforest in Guatemala. It is one of the largest archeological sites and urban centers of the pre-Columbian Maya civilization. It is located in the archeological region of the Petén Basin in what is now northern Guatemala. Situated in the department of El Petén, the site is part of Guatemala's Tikal National Park and in 1979 it was declared a UNESCO World Heritage Site.
GraphemeIn linguistics, a grapheme is the smallest functional unit of a writing system. The word grapheme is derived and the suffix -eme by analogy with phoneme and other names of emic units. The study of graphemes is called graphemics. The concept of graphemes is abstract and similar to the notion in computing of a character. By comparison, a specific shape that represents any particular grapheme in a given typeface is called a glyph. There are two main opposing grapheme concepts.
CuneiformCuneiform is a logo-syllabic script that was used to write several languages of the Ancient Near East. The script was in active use from the early Bronze Age until the beginning of the Common Era. It is named for the characteristic wedge-shaped impressions (Latin: cuneus) which form its signs. Cuneiform was originally developed to write the Sumerian language of southern Mesopotamia (modern Iraq). Cuneiform is the earliest known writing system. Over the course of its history, cuneiform was adapted to write a number of languages in addition to Sumerian.
UnicodeUnicode, formally The Unicode Standard, is an information technology standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. The standard, which is maintained by the Unicode Consortium, defines as of the current version (15.0) 149,186 characters covering 161 modern and historic scripts, as well as symbols, thousands of emoji (including in colours), and non-visual control and formatting codes.
