Chessboard
Board games have been known since ancient history, with the oldest records being paintings in mastabas of the First and Third Dynasties of Egypt (3100-2700 BC). The first known version of chess appeared around the 6th century in India and was called Chaturanga, played on a board of the game Ashtapada. This board was monochromatic and divided into eight columns by eight rows, with special marks called "castles" in the first, fourth, fifth, and eighth squares of the "a", "d", "e", and "h" columns, which served a function in Ashtapada, but not in Chaturanga.
Backgammon
Touraj Daryaee (2006)—on the subject of the first written mention of early precursors of backgammon—writes:
In the 11th century "Shahnameh", the Persian poet Ferdowsi credits Burzoe with the invention of the tables game "nard" in the 6th century. He describes an encounter between Burzoe and a Raja visiting from India. The Raja introduces the game of chess, and Burzoe demonstrates "nard", played with dice made from ivory and teak. Today, Nard is the name for the Persian version of backgammon, which has different initial positions and objectives. H. J. R. Murray details many versions of backgammon; modern Nard is noted there as being the same as backgammon and maybe dating back to 300–500 AD in the Babylonian Talmud, although others believe the Talmud references the Greek race game Kubeia.
