The astute observations of linguist Paul de Lagarde on Persian manuscript in Europe predating 1700 make an essential catalogue for anyone interested in the state of the field in the late 19th century. Citing each manuscript, Lagarde provides an annotated catalogue of 61 pieces that include descriptions from the initial publication of each text as well as his own observations. His study gives a sense of importance of each piece considered, demonstrating their relationships with other known documents. Also included in this unique study are the Judeo-Persian versions of the prophets Isaiah, Jeremiah, and Ezekiel (the latter only through chapter 9).
