Bythner, Victor. לשון למודים (Leshon limudim) Lingua eruditorum. Oxford: William Turner, 1638. Bythner, a Polish-born scholar, taught Hebrew in Oxford and Cambridge. According to Anthony à Wood, he was ‘blessed with a most admirable geny for the obtaining of the tongues’. It is no coincidence that his popular book on Hebrew grammar (it was reprinted and adapted as late as 1853) was part of the collection of the Spanish and Portuguese Synagogue’s Talmud Torah, also called Ets ḥayim. The tradition of studying Hebrew grammar, together with the more traditional subjects of a yeshivah, had already been established by the mother community in Amsterdam.
