The same goes for the Isidorus Mercator of the address. Yeah, Isidore of Seville was an authoritative church father from Spain (significant because of the relationship between the decretals and the Hispana) and Marius Mercator was a widely known translator of Greek texts (significant because the Pseudo-Isidore claims to be presenting new translations of some of the Greek church councils, as we'll see shortly). But what kind of sense does it make to blend the two figures together? Wouldn't that just seem like a stupid joke -- and a clear fiction -- to anybody who knew both authors?
Forging the decretals was obviously deadly serious business for all involved. I guess it's just odd to find our team playing funny games like this.
