"A tract entitled Clypeum Veritatis, otherwise The Shield of Truth, which appeared early in 1618, is a typical deliberation on the pro et contra side, and I am taking it out of due order as it connects with the next tract. It claims (i) to deal with everything which “hereunto has been set forth openly, either for or against the Most Honourable and Blessed Brotherhood of the Rosy Cross,” and (2) to exhibit once and for all that which zealous disciples may expect confidently therefrom. The author in this case also was Irenaeus Agnostus, who subscribes himself (1) as writing from Tunis on February 21 of the year mentioned, (2) by special command of the glorious Brotherhood, he being (3) its “unworthy notary” through- out Germany. It affirms (1) that our highest good and way to the blessed life lies in the knowledge of God; (2) that the man who is devoted to the word of God is ever proceeding further in the quest of wisdom; and (3) that learning must be maintained for the propagation of celestial doctrine.
