Hi Seth,
Although the
lamps shown in your reference may look vaguely similar to the
lamp shown by the OP (Frederic), they are actually very different. The "pattern on the margins" (raised dot decoration) is merely a superficial similarity.
The three
lamps indicated in your reference (Figs. 49, 50 and 159) are typical examples of
lamps made in western
Asia Minor (the
Ephesus area) during the 5th to 6th centuries AD - the
Byzantine period. They are very distinctive and immediately recognisable.
The
lamp shown by the OP was, as I said, made in
North Africa around the 2nd century AD - the
Roman period and much earlier than those
Asia Minor lamps despite the similar decoration.
(Examples of
North African
lamps are shown as Figs. 51, 52 and 161 in your reference but they are later
types and of an entirely different
style.)
By the way, I've been after a copy of Iconomu for some time. If you come across any please let me know.
