The Jewish-Christian controversy, as it is known, includes reflection on the fig- ure of the Nazarene. The richest and most systematic contributions by Jewish tradition to this discourse in the medieval and early modern period are found in Jewish anti-Christian polemical literature.1 In this article I trace the figure of Jesus that was hidden through the polemical and apologetic strategy of the text Sefer Ḥizzuq Emunah (Strengthening of the Faith), composed by Lithuanian Karaite scholar Isaac ben Abraham Troki (c. 1533–1594) at the end of the 16th century. The article reflects on this particular portrait of Jesus, which was read by leading European intellectuals and philosophers.2 Furthermore, the extraor- dinary reception history of this text indicates that Sefer Ḥizzuq Emunah was for a long time a privileged example of what Christians knew about Jewish anti-Chris- tian literature.3 Although Isaac ben Abraham Troki’s biography remains a desideratum, we know that he came from a line of great Karaite scholars and became a leader of his own Karaite community in Troki (Lithuania),4 one of the most important cultural and religious centers of Karaism in the 16th century.5 Isaac ben Abraham Troki was a prolific writer. His literary production covered liturgical poems that include piyutim (םיטויפ), composed in a Turkic language with Hebrew script known as karaim language,6 derushim (םישרד), a homilet- ic interpretation of the Bible, biblical commentaries and a treatise against the Rabbanite.7 Although he belonged to a Karaite group, Isaac ben Abraham knew Talmudic literature well and often cited rabbinic quotations and Jewish classi- cal commentators, an approach found in his main work, the polemical treatise against Christianity Sefer Ḥizzuq Emunah.8 This material was therefore intelligi- ble to a wider Jewish community.

The Karaites therefore reject the Talmud and the rabbinical tra- ditions. Recent scholarship (Polliack 2003, xvii–xviii) has defined Karaite Judaism as “a Jewish religious movement of a scripturalist and messianic nature, which crystallized in the second half of the ninth century in the areas of Persia-Iraq and Palestine […] Karaism, in its spiritual essence and in the grain of its history, should be regarded […] as one manifestation of the multi-faceted nature of Jewish culture and identity”. 6 Kizilov 2007. 7 Akhiezer 2006.
