Quo Fuit places 3 dated presences for Al-Ma'mun across 3 places, from 786 to 809.
Each one keeps the sentence it was taken from and a link to its source.

Every dot is a place Al-Ma'mun is documented in, on a dated record. The interactive globe carries the full detail.

Open Quo Fuit to see these 3 presences on the
globe, filter them by date, and follow the journey year by year.
In each of these, a source puts Al-Ma'mun and the place in the same dated sentence without stating
that Al-Ma'mun was there. They are kept apart from the timeline above for exactly that reason:
a mention is not a presence, and Quo Fuit does not quietly promote one into the other.

How to read this page
Every line above is a dated fact taken from a source, with the sentence it came from and a link
back to it. Nothing is inferred, and a gap in the record is not evidence that someone was elsewhere.
A tag says how the fact is carried by its source: documented a structured,
explicitly dated record, attested a sentence that states the person was there,
mentioned a sentence that ties the person to the place without stating presence.

See Al-Ma'mun on a 3D globe, filter the record by date, and cross this life with another to find
