Note 138 — BOOK II. AN ACCOUNT OF THE WORLD AND THE ELEMENTS.

The æra of the Olympiads commenced in the year 776 before Christ; each olympiad consists of 4 years; the 58th olympiad will therefore include the interval 548 to 544 B.C. The 21st vol. of the “Universal History” consists entirely of a “chronological table,” and we have a useful table of the same kind in Brewster’s Encycl., article “Chronology.”
