According to Wolf ("Bibl. Hebr." ii. 1385), the history of Hebrew typography at Frankfurt-on-the-Main begins with 1625, in which year seliḥot were printed there. But Steinschneider and Cassel declare this statement doubtful. The chronogram of a certain prayer book seems to show that it was printed there in 1656, but this chronogram is known only from references to it in a second edition printed at Amsterdam in 1658 ("Cat. Bodl." Nos. 2149, 2152). It may be said with certainty, however, that Hebrew printing began in Frankfurt not later than 1662, when the Pentateuch with a German glossary was printed. The books printed at Frankfurt up to 1676 do not bear any printer's name.
