Barbavara Ciphers

[Mark Knowles]

Perhaps: cum d(omi)no gorel(l)o origlia

and that's just an embellishment between dno and gorelo / gorello?

There was a "Gorello Origlia". However he seems to have died in 1412 before the date I associate with the cipher. Although maybe he had a son or other relative with the same first name.

D'Gorello

Jacopo Origlia was a 15th-century Italian noble and religious figure. He could have been representing the Kingdom of Aragon, Kingdom of Naples or the Pope.

This could be a completely incorrect identification.
