GIC 475

thunderbolt

rectangular 

5.5–6 x 3.5 mm 

Neapolis (Samaria)

Possibly applied (with GIC 343) by XII Fulminata in the area of Neapolis in perhaps AD 115-117. Another explanation was that the eagle and thunderbolt referred to the cult of Zeus Hypsistos. It is difficult to date the cmks as late as the founding of the temple of Zeus under Hadrian.
