This is a fine example of a Masoretic Bible. “Masorah” means “tradition,” in this case the tradition of how the biblical text is pointed (with vowels) and therefore read. During the manuscript age, copying errors from one text to its copy were quite common, and students of the text lived with this fact. But the books of the Tanakh (Hebrew Bible) were considered to be divine communication, and so such errors—which might change the meaning of the text—were intolerable. To “freeze” the text in its correct form, attention was paid to the rarer words and forms in the biblical text, with the assumption that careful attention would preserve the text in its correct form. The notations surrounding the biblical text—in the margins, at the top of the page and at its bottom—provide the record of these rare forms and where else in the Tanakh (Hebrew Bible) they might be found. 

Despite sharing the concern for accuracy displayed in other Masoretic Bibles, this Tanakh is visually distinct from many. The writing is large and bold, the margins include stylized birds and other figures. This text, written on paper and not parchment, has clearly been influence by the culture in which it was produced—Muslim Yemen of the 15th century. It is a reflection of the fact that Jews, while treasuring and preserving their own tradition, were inevitably part of the cultures in which they made their homes.
