Euclidean geometry Euclidean geometry Euclidean geometry is a mathematical system attributed to Alexandrian Greek mathematician Euclid, which he described in his textbook on geometry: the "Elements". Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions (theorems) from these. Although many of Euclid's results had been stated by earlier mathematicians, Euclid was the first to show how these propositions could fit into a comprehensive deductive and logical system. The "Elements" begins with plane geometry, still taught in secondary school (High School) as the first axiomatic system and the first examples of formal proof. It goes
Ptolemaic cult of Alexander the Great propaganda to support the claims of his own dynasty. As part of this effort, Alexander was elevated from a simple patron god of Alexandria to the status of a state god for the Greek populations of the entire Ptolemaic empire, even beyond the confines of Egypt. During the early Ptolemaic dynasty (), Ptolemy I began the construction of the Tomb of Alexander the Great in Alexandria (the , "sēma", ), and appointed a priest (, "hiereus") to conduct religious rites there.
