Troki, Isaac ben Abraham - Account of his Life
He was born in Troki.He spoke also Latin and Polish and held conversations on theological subjects with Catholic, Protestant and Greek Orthodox clergymen. As a result his famous apology of Judaism, "Hizzuk Emnlunah" (the strengthening of faith), though published only a century after his death, was widely acclaimed and copied. Its penetrating examination of the vulnerable points of Christianity caused it to be translated into Latin with an extensive refutation, under the name "Tela ignea Satanae" (the fiery darts of Satan). Voltaire used some of its arguments and mentioned it as a masterpiece of its kind. Troki might have been dismayed at its notoriety, he had intended it for use by Jewish scholars only. Some of his hymns are included in the official Karaite prayerbook.He is said to have written also some works on Karaite ritual law.
