Proof. Thus probatio viva, or proof alive, was applied to testimony of witnesses; and probatio mortua, or dead proof, to documentary evidence; also, probatio plena and semiplena were technical terms, translatable by "full proof" and "half full," — the one being proof of a public instrument by two witnesses; the other, proof of a private writing by one witness.
