From his early twenties onwards, Beverland focused on compiling a grand work on sexual lust, which would be titled ‘De Prostibulis Veterum’ (‘On the prostitution of the ancients’). By 1677 Beverland contemplated the publication of his ideas and in 1678 he offered a first glimpse of his conclusions in "Peccatum Originale" ("Original Sin"). To silence the criticism he received after his first publication, from members of the Dutch Reformed Church in particular, Beverland decided to edit the work. He published a second edition, "De Peccato Originali" ("On Original sin"), in 1679.
