From extant artifacts it (re)discovers the structure and methods of use of the abaci used by the Romans and peoples before them back to Mesopotamia, and tests the methods by solving perplexing math problems in antiquity (e.g., YBC 7289).

The abaci methods using pebbles and The Salamis Tablet are blindingly fast compared to any other methods available to the ancients. This demonstrated fact is contrary to long held views of many historians that abaci use was cumbersome and slow.

An historical analysis of modern civilizations that did not include the impact of high speed computers would be seriously biased and flawed.

I don't read much about ancient mathematics (my main focus has
been from roughly the late 1700s to the present), but my impression
has been that historians regarded abaci use as being quite fast.
All my math history books are at home, and I'm not, so I can't
check this now (and I don't have time now to usefully search the
google digitized book's archive).
