    Re: Tides by bearing of the moon

    This is the oldest method of determining the time of High (and Low) Tide; it
    was in use at least since the 15th century. One can find descriptions in the
    "Quatri Partitu" of Alonso de Chaves (ca. 1545) and in English in two
    versions of Chaucer's treatise on the astrolabe (which may be later
    additions), not to forget the French booklets by Guillaume Brouscon. A table
    giving the moon's bearings for the main ports at high and low tide was
    included in practically every textbook on navigation well into the 19th
    If you want to read more about it, see: Howse, Some Early Tidal Diagrams,
    in: Mariner's Mirror, Vol. 79 (1993), 27 - 43. The booklets by Brouscon are
    dealt with by Dujardin - Troadec, Les Cartographes Bretons du Conquet. La
    Navigation en Images 1543 - 1650, Brest 1966.
