Now this is interesting:
We have granted to Publius Canidius and his heirs the annual exportation of 10,000 artabas [300 tons] of wheat and the annual importation of 5,000 Coan amphoras [ca. 34,500 gallons] of wine without anyone exacting anything in taxes from him or any other expense whatsoever. ... Let it be written to those to whom it may concern, so that knowing it they can act accordingly.
Make it so!
