Harold Bloom is best known as a champion and staunch defender of the Western canon, see his book, The Western Canon.

The Western canon is (in my view) that body of thought, values, literature, philosophy, and art that underpins cultures from ancient Greece and Rome, to W.Europe and N.America today. It is important as the standard and style of living of billions of people in all senses depends on it. A measure of the importance of the Western canon can be derived by the hostility to it by the so-called progressive/ woke movement.
(The 'School of Resentment', multiculturalists, feminists, Marxists, neoconservatives).

That crowd claim that everything bad is due to us, to the West, that the songs, cuisine, clothes, stories, and so on of all other cultures should be studied but that of the West shall only be denigrated.
Observe that the hostility is mainly white, apart from a few hoping for cash handouts. Yet the other cultures who are not sitting on their backsides- Korea, Japan, China, India, SE Asia- are not destroying their own achievements but are actively absorbing from the Western canon.

The book of Bloom's that I particularly like is The Book of J.
This is a serious and readable study on the authorship of the Bible, suggestions are made as to who wrote various parts. An intriguing idea is that a major contributor was a woman, a senior, at the court of King Solomon, who put together a set of of the old stories for teaching and entertaining children. Bloom portrays the God of the Old Testament as one of the great fictional characters with a personality he describes as egoist.
