Aboa [Turku], Johann Christoph Frenckell, 1762. 4to (22.0 x 19.5 cm). Title page, [iii], 25 pp. No wrappers issued.

A rare and curious thesis, written by the theologist, and professor of Greek and Hebrew, Isaac Ross (1706-1783), and defended by his pupil, Johannes A Gummerus, Satacundensis (i.e., from the historic province of Satakunta in southwestern Finland). Perhaps this is Johann Gumerus, born in 1733 in Vampula (Satakunta), and deceased in 1781 on Lappo, an island situated in the province of Åland, southwest Finland. The work deals with the snake in the Garden of Eden, arguably the first snake. The herpetological importance of this work, however, may be questionable. Uncut, with the widest possible margins. A very good, clean copy.
