Halichoth Olam [“Eternal Ways”]. With Samuel ha-Nagid. Mevo ha-Gemara [“Introduction to Talmud”] / Clavis Talmudica [Key to the Talmud]. Latin translation by Constantin L’Empereur van Oppyck. [Talmudic methodology]

Constantin L’Empereur van Oppyck (1591-1648) was a Dutch Christian Hebraist. He translated the following Hebrew works into Latin: Mishnah, Tractates Midoth and Bava Kama; the Itinerary of Benjamin of Tudela; Ibn Yachya’s Commentary to the Book of Daniel; the commentaries of Abravanel and Alsheich to Isaiah; and finally, the work of the grammarian Moses Kimchi. See EJ, Vol. VIII, col. 42 Mevo ha-Talmud was long attributed - mistakenly - to R. Samuel ha-Nagid of Granada. Recently Prof. Shraga Abramson and others have demonstrated that the true author was R. Samuel ben Chofni Gaon (d. 1013), Gaon of the famed Sura academy in Babylonia, and father-in-law of Hai Gaon. See EJ, Vol. XIV, cols. 807-8
