The map was based on the work of Christian Kruik van Adrichem. Zaddiq explains, in the colophon he prepared for the map, how he copied van Adrichem's map and translated its captions into Hebrew, and that he carefully checked that every detail would be appropriate for his Jewish audience. Zaddiq made some significant changes to the original map. It contained a number of illustrations of Jesus's life at the appropriate places in Canaan, which Zaddiq removed—details such as a miniature illustrating the Exorcism of the Gerasene demoniac and one for the Transfiguration of Jesus on Mount Tabor. On the other hand, he added details appropriate to a Jewish audience, including a number of ships that fly historically important flags: a ship near the Nile delta flies a Muslim flag, signifying the Muslim rule over Egypt, and another off the coast of north Sinai flies the Star of David. According to Rehav Rubin, This Jewish element perhaps gives voice to the author's desire to visit Eretz Yisrael or his deep yearning for the reestablishment of the Judean kingdom.
