Some of these indirect products of Aristotle’s industry were entered upon stone and are still preserved in fragments. The first of these is for convenience referred to as the Fasti (“calendar” or “register”) and contained the annual victors in each event at the City Dionysia from about 502/1 B.C. when volunteer comuses were first given a place in the festival program. This inscription was cut upon the face of a wall built of four rows of superimposed blocks and almost six feet in height. The text was arranged in vertical columns. There were originally sixteen of these and most of them contained one hundred and forty-one lines. The presence of a heading over the first five columns, however, reduced the lines upon them to one hundred and forty. For the most part the lines in adjoining columns were placed exactly opposite one another, but toward the bottom of col. 13 the writing was crowded so that this column perhaps contained no less than one hundred and fifty-three lines. As the entries for 346-342 B.C. fell in this space, most authorities accept Dr. Wilhelm’s conclusion that the body of the inscription was cut at that period and received additional entries, year by year, for subsequent festivals until about 319 B.C.[373] Whoever was responsible for the original inscription must have excerpted the appropriate items from Aristotle’s _Didascaliae_ and, for the brief period intervening between the publication of Aristotle’s book and 346-342 B.C., from the original archives.
