Thanks. Possibly the Chinese took over the Roman abacus. There were indeed trade relations (e.g. Asia minor: Antikythera mechanism; silk road). ----Ursprüngliche Nachricht---- Von : jcortada@umn.edu Datum : 20/02/2019 - 22:11 (MZ) An : marcweber@att.net Cc : herbert.bruderer@bluewin.ch, members@sigcis.org, members@lists.sigcis.org Betreff : Re: [SIGCIS-Members] History of Rome. How did they calculate? Well, if we going retro, I theorize it is the following that they used since new thinking in Roman historiography suggests the Romans had contact with Asian markets.

Hi all: Does anyone know how the Romans calculated with the Roman numeral system? What is the meaning of the right-most slot of the Roman hand abacus? Do you have Roman hand abaci (original devices or replicas) in your collection? Thank you very much for your help.
