In 1633 the eminent French humanist FABRI de PEIRESC, in forwarding to KIRCHER, a sketch of letters engraved on the sword of GUSTAVUS ADOLPHUS , pointed out that they: "ne sont pas sans qudq rapport d'ailleurs de vos alphabets de Barachias, si la memoire no me trompe" v. PUG. 568 f. 364. Aix, 30 March 1633.,
