Hillel ben Eliakim
Hillel ben Eliakim (known as Rabbenu Hillel) was a Greek-speaking talmudist who lived in Silivri near Constantinople, or perhaps in Salonika. He is best known for his commentaries on selected tannaitic midrashim, which circulated among the Tosafists in northern Europe and rabbinic authors in Provence. His published commentary on the Sifra and Sifre is a straightforward exegesis of rabbinic works. Hillel draws on several earlier authors, including Hayya Ga’on (939–1038), Rashi (1040–1105), and Nathan ben Yeḥiel (1035–ca. 1110). He often compared Sifra and Sifre with the Talmud and would frequently translate Hebrew terms into Greek. He also wrote responsa and other commentaries.
