Mosque details
It looks like a minbar, but at the top there is a sundial.
The actual sundial.
Koranic inscription on one of the columns, right in from the main entrance.
With its simplicity, the detail of the Great Mosque becomes quite effective. In the courtyard there are a number of objects which seems like they were randomly placed there during an excavation or something. But in fact, it is a question of 4 wellheads, looking like the base of Roman columns, a drain and a minbar-like sundial. There is a second sundial on the eastern colonnade, which was used in afternoons.
Drain in the middle of the courtyard, used to collect rainwater which was preserved in underground cisterns. Note what looks like useless decorations around the hole. It is really made to remove dust from the water before it came to the hole.
