Boston: Harvard University Press, 1957. First edition. 8vo, 328  pp, hardcover in dust jacket. Includes a bibliography and index.
Bouwsman's important work on the remarkable religious universalist, astronomer, linguist, Cabbalist and diplomant, long out of print and scarce.
Very good, with some toning to paper and slight creakiness to rear hinge. The dust jacket has a long tear along the front gutter, and additional toning and chipping - fair only. Item #27413
