Collon, Dominique & John Curtis. 2017. “Some stamp seals of Achaemenid date“, In Y. Heffron, A. Stone and M. Worthington (eds), At the Dawn of History: Ancient Near Eastern Studies in Honour of J.N. Postgate, 765-780. Winona Lake, Indiana: Eisenbrauns.
This paper discusses a collection of 17 distinctive bronze stamp seals. They are all plaques or tablets of bronze, more or less flat on both surfaces, and square or rectangular in shape. More than half of them have a distinctive ladder-pattern border around the decorated face of the seal. The designs are usually highly stylized but sometimes more naturalistic. These seals may be compared with a stone seal from Nimrud and a silver ring from Kamid el-Loz. They apparently date from the Achaemenid period, 5th-4th century BC, and probably derive mostly from the western part of the Persian empire.
