How they got to Ispahan I was unable to discover.

They are very old, and evidently by good masters.
The way back to our comfortable quarters at Djulfa lay over the Zandarood river.

There are five bridges, the principal one being that of Allaverdi Khan, named after one of the generals of Shah Abbas, who superintended its construction.

It is of solid stonework, and built in thirty-three arches, over which are ninety-nine smaller arches above the roadway on both sides, enclosing a covered-in pathway for foot-passengers.

The roadway in the centre, thirty feet wide, is well paved with stone, and perfectly level.
