Harris Horblit, 100 Books Famous in the History of Science, 1964 was the topic of an earlier blog post.
Here I present: Euclid, The Elements’, 300 BC. Harrison Horblit listed Euclid, The Elements’, 300 BC as the earliest of his books in the history of science.
INTRODUCTION.
Geometry was one of the two (2) fields of prehistoric mathematics, the other being Arithmetic (study of numbers).
Geometry means Earth measurement. Early people used Geometry to build roads, temples, pyramids, and irrigation systems.
Euclid was a Greek mathematician who lived in Alexandria, EGYPT, during the reign of Ptolemy-I, placing his writing around 300 BC.
Euclid (300 BC) organized Greek geometry into a 13-volume set of books named The Elements’, in which the geometric relationships were derived through deductive reasoning. Thus, today’s geometry is often called Euclidean Geometry, also known as plane geometry because the relationships deal with flat surfaces.

COMMENT.
Numeral is a syntactic element’. Syntax elements’ include: noun, verb, adverb, pronoun, adjective, article, preposition, conjunction, interjection and numeral.
Arithmetic (study of numbers) is prehistoric before the advent of writing.
Speech can convey arithmetic and geometry, as it did in ancient and prehistoric times.
