Clean Monday
Clean Monday is a public holiday in Greece and Cyprus, where it is celebrated with outdoor excursions, the consumption of shellfish and other fasting food, a special kind of azyme bread, baked only on that day, named "lagana" () and the widespread custom of flying kites. Eating meat, eggs and dairy products is traditionally forbidden to Orthodox Christians throughout Lent, with fish being eaten only on major feast days, but shellfish is permitted in European denominations. This has created the tradition of eating elaborate dishes based on seafood (shellfish, molluscs, fish roe etc.). Traditionally, it is considered to mark the beginning of the spring season, a notion which was used symbolically in Ivan Bunin's critically acclaimed story, "Pure Monday".
Anan ben David
In addition, he maintained that as long as Israel is in exile the flesh of animals, with the exception of the deer, the pigeon and the turtle-dove, is forbidden from being eaten (although permitted animals may be eaten with dairy). Within Judaism, restrictions on consuming meat and poultry that extend beyond the Rabbinic concept of kashrut are not unique to Ananism—the Talmud relates that after the destruction of the Second Temple certain ascetics (perushim) such as Abu Isa sought to prohibit meat and wine because they had been employed in the Temple ritual, and that Rabbi Joshua ben Hananiah repressed the movement. In modern times, Rabbi Abraham Isaac Kook, the first Ashkenazic chief rabbi of the British Mandate for Palestine, argued that vegetarianism is supported in the Tanakh as a Jewish ideal.
