פירוש על עבודה זרה 106:17

Ulla graphically disagrees with R. Judah, quoting, not incidentally, a tradition ascribed to two Eretz Yisraeli sages. According to both of them, even those who hold that broken fragments of idols are prohibited, this is because they do not annul idols even when broken. But pedestals are not themselves worshipped, so when a pedestal breaks, they just throw it away and get another one.
