Panel painting

In the process of examining a panel painting recently, I have
discovered a wax seal on the back (panel painting, possibly
sixteenth or seventeenth century Italian).

The heraldry contains: a hat (cappello romano or saturno worn by
bishops and cardinals), rope (with 12 tassels coming off which is
likely to mean Bishop), an eagle and a cherub.  The legend refers to
Saints Nazarius and Celsus, but the rest is in a mixture of Latin,
French and Spanish. There is a corresponding panel mark with two
"SS" with a chalice in between. I am looking for someone who might
help me decipher it and I would be happy to send an image.
