From the Roman Board Games website:

In Roman antiquity this game was known as alea, meaning "gambling", but came to be called Tabula, "board" or "table", since it was played on a board. Alea dates back to several centuries BCE and appears to have evolved directly from Duodecim Scriptorum, the game of Twelve Lines. Tabula bears some similarity to Egyptian Senet, which dates back to at least 3000 BCE.'

From the BGG entry:

'A version of Ludus Duodecim Scriptorum, the Roman precursor to Backgammon. Players move their stones round the 24 place track, knocking each other off as they go.'
