326. A longer, and consequently more exact period than the above-mentioned § 320, for comparing and examining Eclipses which happen at long intervals of time, is 57 _Julian_ years 324 days 21 hours 41 minutes and 35 seconds; in which time there are just 716 mean Lunations, and the Sun is again within 5 minutes of the same Node as before. But a still better period is 557 years 21 days 18 hours 30 minutes 12 seconds; in which time there are 6890 mean Lunations; and the Sun and Node meet again so nearly as to be but 11 seconds distant. [Sidenote: An account of the following catalogue of Eclipses.] 327. We shall subjoin a catalogue of Eclipses recorded in history, from 721 years before CHRIST to _A. D._ 1485; of computed Eclipses from 1485 to 1700; and of all the Eclipses visible in _Europe_ from 1700 to 1800. From the beginning of the catalogue to _A.D._ 1485 the Eclipses are taken from STRUYK’s _Introduction to universal Geography_, as that indefatigable author has, with much labour, collected them from _Ptolemy_, _Thucydides_, _Plutarch_, _Calvisius_, _Xenophon_, _Diodorus Siculus_, _Justin_, _Polybius_, _Titus Livius_, _Cicero_, _Lucanus_, _Theophanes_, _Dion Cassius_, and many others. From 1485 to 1700 the Eclipses are taken from _Ricciolus_’s _Almagest_: and from 1700 to 1800 from _L’art de verifier les Dates_[73]. Those from _Struyk_ have all the places mentioned where they were observed: Those from the _French_ authors, _viz._ the religious _Benedictines_ of the Congregation of St. _Maur_, are fitted to the Meridian of _Paris_: And concerning those from _Ricciolus_, that author gives the following account.
