Open Quo Fuit to see these 12 presences on the
globe, filter them by date, and follow the journey year by year.
In each of these, a source puts Paul Cohen and the place in the same dated sentence without stating
that Paul Cohen 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.

Two people documented in the same place in the same year is a correlation, not a meeting.
Quo Fuit will never say they met without a source that says so.
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.
