פירוש על עבודה זרה 15:7

This is an etymological story of the origins of Kalenda and Saturnalia. Some scholars also point to this story as the origin of why we light candles on Hannukah. Holidays around the winter solstice are often associated with fire, as a way of noting the beginning of the days getting longer, or to at least bring light to the darkest days of the year (in the northern hemisphere). There is also a sense here of cultural expropriation—your holidays were originally our holiday (in a sense) and you corrupted them. While there is of course a negative side to this phenomenon, the supremacist ideology it espouses, it also seems to me quite natural.
