This detail is from the title page of Kikayon Yonah by Jonah ben Isaac Teomim (1712), and shows the printer’s device through which we can peep in to an eighteenth-century printing workshop.

The device belongs to a Calvinist theologian and Hebraist, Heinrich Jacob von Bashuysen, who established a Hebrew printing house in Hanau in the early 1700s. More than one hundred works were published here, many of which was written by Bashuysen himself.
Have a look at the publication information under the device:
