Additional 18851, f. 6v: calendar page for November

This calendar page, for the month of November, contains another unusual depiction of a zodiac sign.  Sagittarius, the archer, is commonly shown as a centaur (half-man, half-horse), but in this instance his lower body appears to be a lion.  Below, the work of fattening hogs and cattle continues, while two men in the lower left seem to be engaged in a sale of livestock.
