(16) The essay published in French by Alexandre Lenoir in 1809, while curious and original, contains little real information on the Tablet, which the author seeks to prove was an Egyptian calendar or astrological chart. As both Montfaucon and Lenoir--in fact all writers on the subject since 1651--either have based their work upon that of Kircher or have been influenced considerably by him, a careful translation has been made of the latter's original article (eighty pages of seventeenth century Latin). The double-page plate at the beginning of this chapter is a faithful reproduction made by Kircher from the engraving in the Museum of Hieroglyphics. The small letters and numbers used to designate the figures were added by him to clarify his commentary and will be used for the same purpose in this work.
