What metaphors are used in The Spinoza of Market Street by Isaac Bashevis Singer?

Singer is credited with preserving the memory of this rich culture through the settings and metaphor of his fictional stories in the context of the Jewish world in which he grew up. In addition, Singer's stories, written in Yiddish and meticulously translated into English, in themselves represent an effort to preserve the Yiddish language, also severely devastated by the death of much of the world's Yiddish-speaking population in the Holocaust.
