Pirkei deRabbi Eliezer פרקי דרבי אליעזר

The book opens with a story about Rabbi Eliezer ben Hyrcanus himself: how, grown and unlearned, he left home to study—and only then turns to Creation. Then come the ten utterances by which the world was made, the ten trials of Abraham, the ten wonders in Egypt and at the sea: everything set out in tens.

From it come many details everyone knows without knowing their source: that Asenath was Dinah's daughter, that Elijah and Phinehas are one man, that the moon was diminished. By scholarly dating the book was composed in the eighth or ninth century; the name of Rabbi Eliezer, who lived seven hundred years earlier, stands on it as the hero of the first chapters, not as its compiler.
