"This volume aims to introduce the reader to Greek and Roman ways of expressing numbers, weights and measures - matters often relegated to footnotes or tabulations in an appendix. Yet the words, the symbols and the calculations used in the classical world have an interest in themselves and often reveal unexpected facets of the culture which employed them." "The book is, quite simply, an indispensable point of reference for every student of ancient texts or of classical culture in general."--Jacket.
