Emily Dickinson Lexicon

CHRO-NOL'O-GY, n. [Gr. χρονολογια; χρονος, time, and λογος, discourse or doctrine.]

The science of time; the method of measuring, or computing time by regular divisions or periods, according to the revolutions of the sun, or moon; of ascertaining the true periods or years when past events or transactions took place; and arranging them in their proper order according to their dates. If history without chronology is dark and confused; chronology without history is dry and insipid. – A. Holmes.
