We don’t usually look at this object from this direction, so I will give you a big clue and tell you what it is called.
This is a fanoos.
What is a fanoos?
Florence Nightingale is often know as ‘the lady with the lamp’, and this is the lamp.
A fanoos is a Turkish lamp that collapses down flat when not being held or hung up. It was the light that Miss Nightingale carried as she walked the 3 miles from one end of Scutari Hospital to the other.
