    Re: Ptolemy Stone...?
    From: Alexandre Eremenko

    Dale,
    Here is the reference on the Ptolemy's column that I mentioned:
    
    http://www.caeno.org/pdf/Evans_Greek%20variable%20calendars_Ptolemy%20Canobus%20stela.pdf
    
    It is called "Ptolemy's stella" in this text.
    
    The official name is "Canobus inscription". Full translation is in the second volume
    of Opera omnia of Ptolemy edited by Hedberg, Lepizig 1907.
    
    It contains not only the inclination of ecliptic but all constants
    (length of the year, various periods of the moon, periods, excentricities and inclinations
    of planets etc.) necessary to use his planetary theory.
    
    Probably Ptolemy anticipated the coming of the Dark Age, and thought that these precious data
    will be better preserved in stone rather than on papirus.
    He was mistaking:-)
    
    Alex.
