of this particular person. The name of this king on coins is 
generally written Zam; but on a drachm in the Bartholomaei 
Collection (Plate XVIII, Fig. 8) and on others described by 
Mordtmann (Z.D.M.G., 1865, p. 440, No. 100 ; and 1880, p. 109) 
the name is written in full amasp. Drouin (Les Légendes 
des Monnaies Sassanides, p. 39) seems to believe erroneously 
that this reading should be Zam af(zut). Thomas (Sassanians 
in Persia, p. 66 sq.) attributes the coins of Jimasp wrongly to 
Hormazd III (457-459) and Rapson (J.R.A.S., 1904, p. 679, 
fig. 10 of the Plate) assigns a drachm to Jamasp, which in 
reality is one of Kobad I (488-497 and 499-531). Vincent 
Smith (Indian Museum Catalogue, Vol. 1, p. 226) assigns erro- 
neously a drachm of Jamasp to Firdz I (459-484).
