Seder for Tu BiShvat — written by an unknown author from the school of Rabbi Isaac Luria (Arizal) — first published as a pamphlet in Venice in 1728. It contains four basic sections: After an introduction that explains the basis for the Tu BiShvat seder, there is a prayer to be said before the actual seder begins. This is followed by a description of the order of the fruit to be eaten and the way wine should be blended in each of the four cups. The bulk of the seder consists of selections from the Bible, early rabbinic texts, and the greatest portion of this material is taken from the Zohar.
