This English translation of a Latin work De termino vitae (Roth Collection 632) is a treatise on free will and determinism. It was originally published by Menasseh himself as ‘Tseror hahayim; De termino vitae: libri tres’ in 1639.
The original edition was dedicated to the managing directors of the West India Company, which was co-founded by Jewish merchants. It was prefaced by a eulogy by Johan van Beverwijck (1594–1647), a noted physician and author of a medical treatise on the nature of women.
Menasseh’s text was followed by a Latin "Carmen intellectuale" by Jacob Rosales, alias Manoel Bocarro Francês, (1593–1662), a medical author and correspondent with Galileo. Rosales dedicated his piece to van Beverwijck, an illustration of the ties between Jewish and Christian scientists.
