Incunabulum (incunabula, in the plural) is a Latin word meaning diaper or cradle. The term refers to books published during the early years following the invention of printing, approximately in the period 1445-1500. It is usually assumed that some 35,000 books were printed during this period, of which over 200 were in Hebrew. Rashi’s Commentary on the Torah is the first Hebrew-language book whose place (Italy) and date (5235) of printing are specifically stated in the work itself.
Incunabula are rare books of great historical and cultural value, and accordingly they are priceless.
