In page Eldad ha-Dani:

"

Metz was the first to analyze the contents of Eldad's book in the light of the reports of other travellers.[1] Abraham Epstein followed Metz's method, and came to the conclusion that Eldad's book is like a historical novel in which truth is mixed with fiction.[2][3] According to Epstein, the Halakhot and laws described by Eldad are genuine, and were in use among the countrymen of Eldad, either in a province of eastern Africa or in Yemen, where the Jews at that time knew Hebrew, but did not recognize the Talmud. Eldad could not have been a native of Ethiopia, the country of the Beta Israel, since no trace of Ge'ez appears in Eldad's Hebrew. There are some traces of Arabic, which Eldad must have known, although he asserted the contrary.[citation needed]
