What to Burn? - Shabbat 20
Today’s Talmud page does not explore this historical or theoretical background, but rather the rules about fire and Shabbat candles stipulated in the Mishnah texts under consideration. These Mishnah texts also take the Pharisaic/Rabbinic perspective on the issue as a given, so they are more concerned with the mechanics of following through on that approach. After all, fire is an active chemical process, and often requires stirring or adding wood which could be considered conscious interventions to “kindle” a fire as forbidden on Shabbat. So in general logs should catch fire through the “greater part,” says the Mishnah, and the Talmud explores what that means – of each log or the entire pile? Of its thickness or circumference, or both? Or another way to think about it, so that an artisan would not use it for something else. And we have the predictable debate of which burning materials need to catch fire “through the greater part” and which do not.
In that same vein of materials, we also read about what materials may serve as acceptable wicks for Shabbat candles, and what may not. The reasoning behind these exclusions is not explored until tomorrow’s page, because they are more interested in what materials the Mishnah is talking about – the vocabulary has changed enough that they are not sure what each word means? Some rabbis even say, “I asked nekhutay yama [seafarers] what it is” to find out what the Mishnah’s rabbis meant. In other words, as much as the Talmud claims to be an organic and precise transmission of oral tradition from the earliest generations of Jewish legend through Pharisees and early Rabbis, sometimes they just don’t know what the words mean any more.
