These first four
lamps are all
types found in Jordan but I'm afraid your doubts about their authenticity are probably correct:
1 & 4) Both are likely to be
fake. A large number of
fake copies of these distinctive 'Jerash'
lamps with zoomorphic handles began circulating on the market about fifteen years ago. They are much fatter and cruder than the real ones.
3) Crude
fake of the 'Darom' (northern variety)
type.
2) Another
type of
lamp found in Jordan but also likely to be
fake.
If they were real, only number 3 would be of the
Roman period; the others would be of the
Byzantine or
Islamic periods.
