Hieroglyphic in the context of "Middle Egyptian language"

Cretan hieroglyphs are a hieroglyphic writing system used in early Bronze Age Crete, during the Minoan era. It predates Linear A by about a century, but the two writing systems continued to be used in parallel for most of their history. As of 2025, it is undeciphered.

The writing systems used in ancient Egypt were deciphered in the early nineteenth century through the work of several European scholars, especially Jean-François Champollion and Thomas Young. Ancient Egyptian forms of writing, which included the hieroglyphic, hieratic and demotic scripts, ceased to be understood in the fourth and fifth centuries AD, as the Coptic alphabet was increasingly used in their place. Later generations' knowledge of the older scripts was based on the work of Greek and Roman authors whose understanding was faulty. It was thus widely believed that Egyptian scripts were exclusively ideographic, representing ideas rather than sounds. Some attempts at decipherment by Islamic and European scholars in the Middle Ages and early modern times acknowledged the script might have a phonetic component, but perception of hieroglyphs as purely ideographic hampered efforts to understand them as late as the eighteenth century.

The Rosetta Stone, discovered in 1799 by members of Napoleon Bonaparte's campaign in Egypt, bore a parallel text in hieroglyphic, demotic and Greek. It was hoped that the Egyptian text could be deciphered through its Greek translation, especially in combination with the evidence from the Coptic language, the last stage of the Egyptian language. Doing so proved difficult, despite halting progress made by Antoine-Isaac Silvestre de Sacy and Johan David Åkerblad. Thomas Young, building on their work, observed that demotic characters were derived from hieroglyphs and identified several of the phonetic signs in demotic. He also identified the meaning of many hieroglyphs, including phonetic glyphs in a cartouche containing the name of an Egyptian king of foreign origin, Ptolemy V. He was convinced, however, that phonetic hieroglyphs were used only in writing non-Egyptian words. In the early 1820s Champollion compared Ptolemy's cartouche with others and realised the hieroglyphic script was a mixture of phonetic and ideographic elements. His claims were initially met with scepticism and with accusations that he had taken ideas from Young without giving credit, but they gradually gained acceptance. Champollion went on to roughly identify the meanings of most phonetic hieroglyphs and establish much of the grammar and vocabulary of ancient Egyptian. Young, meanwhile, largely deciphered demotic using the Rosetta Stone in combination with other Greek and demotic parallel texts.

In mathematics, the regula falsi, method of false position, or false position method refers to a family of algorithms used to solve linear equations and smooth nonlinear equations for a single unknown value.In its oldest known examples found in cuneiform and hieroglyphic writings, the method replaces simple trial and error with proportional correction of an initial guess. In modern usage, the method relies on linear interpolation based on two different guesses.
