And it came to pass, that in process of time, at the end of two years, his bowels fell out by reason of his sickness, and he died of sore diseases. And his people made no burning for him, like the burning of his fathers.
Mishnah Avodah Zarah
These are the festivities of the idolaters: Kalenda, Saturnalia, Kratesis, the anniversary of accession to the throne and birthdays and anniversaries of deaths, according to Rabbi Meir. But the Sages say: a death at which burning [of articles of the dead] takes place is attended by idolatry, but where there is not such burning there is no idolatry. But the day of shaving ones beard and lock of hair, or the day of landing after a sea voyage, or the day of release from prison, or if an idolater holds a banquet for his son the prohibition only applies to that day and that particular person.
