ローマ帝国のサイコロ

うおー、これで GURPS Imperial Rome をプレイしたい。と思ったが、GURPS では D20 って使わないんだったな。2世紀頃のローマ帝国だから五賢帝の頃か。何かのゲームに使われていた20面体サイコロらしい。

A ROMAN GLASS GAMING DIE

A ROMAN GLASS GAMING DIE
Circa 2nd Century A.D.
Deep blue-green in color, the large twenty-sided die incised with a distinct
symbol on each of its faces
2 1/16 in. (5.2 cm.) wide
Acquired by the current owner's father in Egypt in the 1920s.
Several polyhedra in various materials with similar symbols are known from the Roman period. Modern scholarship has not yet established the game for which these dice were used.

直径 5.2cm って結構でかいな。
