The mathematical work of Anania Shirakatsi
Abstract: This paper aims to give a brief account of the mathematical work of the 7th-century Armenian polymath and natural philosopher Anania Shirakatsi. The three sections of Anania's ``Book of Arithmetic'' -- tables of arithmetic operations, a list of problems and their answers, and a collection of entertaining puzzles -- are presented and discussed, the focus being on the problems and solutions. A close examination of the structure of these problems reveals that Anania's proficiency in arithmetic was considerably more sophisticated than their mathematical contents might suggest. The geography of Anania's problems is illustrated through two maps highlighting the locations referenced within these problems.
