Although the inscriptions from ancient South Arabia were already known by the 18th century, it was Wilhelm Gesenius (1786-1842) and his student Emil Rödiger who finally undertook the deciphering of the script, actually independently of each other, in the years 1841/42. Then in the second half of the 19th century Joseph Halévy and Eduard Glaser brought hundreds of Old South Arabian inscriptions, possible tracings and copies back to Europe. On the basis of this large amount of material Fritz Hommel prepared a selection of texts in 1893 along with an attempt at a grammar. Later on the Sabaean expert Nikolaus Rhodokanakis made especially important steps towards understanding Old South Arabic. A completely new field of Old South Arabian script and texts has been opened up since the 1970s by the discovery of wooden cylinders on which Sabaean has been written with a pen. The unknown script and numerous incomprehensible words presented Sabaean studies with new problems, and to this day the wooden cylinders are not completely understood.
