And he that maketh a Covenant with the Author, by mediation of the Actor, not knowing what Authority he hath, but onely takes his word; in case such Authority be not made manifest unto him upon demand, is no longer obliged: For the Covenant made with the Author, is not valid, without his Counter–assurance. But if he that so Covenanteth, knew before hand he was to expect no other assurance, than the Actors word; then is the Covenant valid; because the Actor in this case maketh himselfe the Author. And therefore, as when the Authority is evident, the Covenant obligeth the Author, not the Actor; so when the Authority is feigned, it obligeth the Actor onely; there being no Author but himselfe.
