Church of the Nativity: 1940

That's a Queen Elizabeth Hat, very stylish among British women of a certain age between about 1937 and 1940.

(Referring to the late Queen Mother, of course, who became Queen Consort at the end of 1936.)

Judging by the western ladies hats the date would be more like 1928-1930 I think.

The hanging things are oil lamps, not censers. Just above the lamps themselves are oval ostrich eggs -- a symbol of hope and the Resurrection. The lamps are lowered during the day to be refilled and have their wicks trimmed. Orthodox churches in Jerusalem and elsewhere have dozens of these lamps, many of them donated over the centuries by Christian pilgrims.

What are the things hanging in the picture? Incense?
