Campanella. It is a farrago of vanities, has no order, many obscurities,
and perpetual barbarisms. One thing I have learned in wandering through

Authorities differ with regard to the ultimate fate of this author. Some
say that he was killed in prison in 1599; others declare that he was
released and fled to France, where he enjoyed a pension granted to him by
Richelieu. However, during his incarceration he continued his studies, and
wrote a work concerning the Spanish monarchy which was translated from

him into enterprises which were outside the proper sphere of his
philosophy. In this he followed the example of many other luckless
authors, to whom the advice of the homely proverb would have been valuable
which states that "a shoemaker should stick to his last."

sentences were reversed by the Parliament of Paris in 1777. This book has
often been reproduced and translated in other languages. De Lisle was
exposed to the persecutions of the Reign of Terror, and another work of
