Keter Torah, the 613 mitzvot and seven Rabbinic mitzvot. Rabbi David Vital. Constantinople, 1536. Printed by Eliezer ben Gershom Soncino.
The author, Rabbi David Vital (amongst the Jews expelled from Spain and a rabbi in Italy, son-in-law of the Mahardach of Corfu), based his work on a poem of 620 words [the numerical value of the word Keter in Hebrew], and each word hints to another mitzvah of the 613 mitzvot and of the seven Rabbinic mitzvot. The acrostic (acronym of the poem) is composed of the letters of the full version of the Ten Commandments. Most of the book is an explanation of the hints in the poem with laws and novellae on each mitzvah.
The book has more poems by the author. Also printed are illustrations of "hands" for calculating the tekufot and an illustration of the innards of an animal [for laws of treifot].
