Amongst the fanatics whose works were fatal to them must be enrolled the famous advocates of polygamy, Johann Lyser, Bernardino Ochino, and Samuel Friedrich Willenberg. Lyser was born at Leipsic in 1631, and although he ever remained a bachelor and abhorred womankind, nevertheless tried to demonstrate that not only was polygamy lawful, but that it was a blessed estate commanded by God. He first brought out a dialogue written in the vernacular entitled _Sinceri Wahrenbergs kurzes Gespraech von der Polygamie_; and this little work was followed by a second book, _Das Koenigliche Marck aller Laender_ (Freyburg, 1676, in-4). Then he produced another work, entitled _Theophili Aletaei discursus politicus de Polygamia_. A second edition of this work followed, which bore the title _Polygamia triumphatrix, id est, discursus politicus de Polygamia, auctore Theoph. Aletoeo, cum notis Athanasii Vincentii, omnibus Anti-polygamis, ubique locorum, terrarum, insularum, pagorum, urbium modeste et pie opposita (Londini Scanorum_, 1682, in-4). On account of the strange views expressed in this work he was deprived of his office of Inspector, and was obliged to seek protection from a powerful Count, by whose advice it is said that Lyser first undertook the advocacy of polygamy. On the death of his friend Lyser was compelled frequently to change his abode, and wandered through most of the provinces of Germany. He was imprisoned by the Count of Hanover, and then expelled. In Denmark his book was burned by the public executioner. At another place he was imprisoned and beaten and his books burned. At length, travelling from Italy to Holland, he endured every kind of calamity, and after all his misfortunes he died miserably in a garret at Amsterdam, in 1684. It is curious that Lyser, who never married nor desired wedlock, should have advocated polygamy; but it is said that he was led on by a desire for providing for the public safety by increasing the population of the country, though probably the love of notoriety, which has added many authors' names to the category of fools, contributed much to his madness.
