Well, you could go to a big library and look for the eclipse canons of Oppolzer or Meeus and Mucke. Now we have a much better reply, at least for eclipses of the Moon. Each page contains the data for 70 consecutive lunar eclipses, one event per line. Clearly the book isn't a mere observing guide, for three of its pages would span the entire lifetime of any one person. Such a canon has many uses.
Historians can often deduce exact dates of ancient writings simply because an eclipse is mentioned.
Comparisons between early records and modern eclipse calculations have already revealed, in detail, how the Earth's rotation rate has been slowing during the past three thousand years. What most distinguishes the Liu-Fiala canon is its improved accounting for this variable rotation effect, plus its use of new analytical expressions for the motions of the Moon and Sun developed by French astronomers within the last decade. 91 minutes later, respectively. Tucked in a sleeve are acetate overlays for polar and Mercator maps, allowing a reader to find out in seconds where on Earth any given eclipse can be seen. Whether exploring the power of Stonehenge as an eclipse predictor or engaging in other numerological exercises, many people find endless fascination in eclipse cycles.
