Just as it was necessary to leave out many of the images, there was also wealth of information about the customs they depicted that needed to be pared down into succinct captions. One illustration that intrigued me more than the others was Tu b’Shevat, or “The New Year for Trees.” A New Year for Trees? I was intrigued, so I looked to see what The Book of Customs had to say about it:
This was the date on which the year was determined for tithing of fruit trees during Temple times. Since a tenth of the fruit was obligated to be given to the Levites and Temple each year, it was necessary to calculate from a measurable turning point in the growing season.
At first I was disappointed by this description — to me it sounded like celebrating tax day as a holiday. But as I read further, Tu b’Shevat revealed itself as a great testament to the ability for customs to take on a life of their own. It turns out that many traditions have been built around the holiday — from simply eating fruit to reciting passages in the Bible, Talmud, and Kabbalah related to fruit. More recently, Tu b’Shevat is interperated by many as a kind of Jewish Arbor Day — an occasion for celebrating the environment, planting trees, and raising ecological awareness.
The truth is that many of the customs shown in this slideshow followed a similar historical trajectory, becoming abstracted from their original purpose — and of course, Judaism doesn’t hold a monopoly on this sort of evolution. What kind of traditions have you observed that have expanded out from their origins — for New Years, for trees, or otherwise?
