November (Roman month) favored the cult of Isis. The Romans did not number days of a month sequentially from the first day through the last. Instead, they counted back from the three fixed points of the month: the Nones (5th or 7th), the Ides (13th or 15th), and the Kalends (1st) of the following month. The Nones of November was the 5th, and the Ides the 13th. The last day of November was the "pridie Kalendas Decembrīs," "day before the Kalends of December". Roman counting was inclusive; November 9 was "ante diem V Idūs Novembrīs", "the 5th day before the Ides of November,"
September (Roman month) may represent a magico-medical charm to ensure healthy wine, with the lizard either a potent lustration or the potential damage to be warded off. The lizard is also an attribute of Apollo Sauroctonos. In calendar mosaics from Hellín in Roman Spain and Trier in "Gallia Belgica", September is represented by the god Vulcan, the tutelary deity of the month in the "menologia rustica", depicted as an old man holding tongs. The mosaic from Hellín (2nd–3rd century) depicts each of the months as a personification with or representing a zodiac sign. September is shown holding balance scales and assisted by Vulcan.
