My maker's life is my food


this is for a screenplay for a fantasy film. There is a magic table (Mensa Magica, did I get that right?...) and in the Book it says in Latin -- "My maker's life is my food". Or, "I eat my maker's life."

It is a riddle the meaning of which is: for the table to function, it needs the blood of the man who made the table (his "life", as blood symbolizes life.)

Thank you in advance!
