Lately, I came across “Lostafeln”, “lot tables” (with “lot” as in “fate”), something like a horoscope. Look at these pictures, drawn from two early fifteenth-century books.
Is it just me or could they have been the role models for the notorious f57v…?
I’m particularly intrigued by the concentric rings with the “start” markers, and the alphabetic letter sequences.
