His writings, all in Dutch, flowed in a continuous stream from 1524 (though none is extant before 1529) and amounted to over 200 in number. His
magnum opus was '
T Wonder Boeck (
n.d. 1542, divided into two parts; 1551, handsomely reprinted, divided into four parts; both editions anonymous). Its chief claim to recognition is its use, in the latter part, of the phrase
Restitutio Christi, which apparently suggested to
Servetus his title
Christianismi Restitutio (1553). In the first edition is a figure of the "new man," signed with the author's monogram, and probably drawn as a likeness of himself; it fairly corresponds with the alleged portrait, engraved in 1607, reproduced in the appendix to
Alexander Ross's
Pansebeia (1655), and idealized by P. Burckhardt in 1900. Another work,
Verklaringe der Scheppenissen (1553) treats mystically the
Book of Genesis, a favourite theme with
Böhme,
Swedenborg and others. ==References==
