Iron meteorite, octahedrite (IID, Om)
Fall, ~1400; 107 kg

A rounded Fe-rich mass (50 x 30 x 20 cm)— often alluded to as "Der verwünschte Burggraf" ["The bewitched burgrave"] — was preserved for centuries in Elbogen before being recognized as meteoritic by the scientific community in the early 19th Century. For three decades of the 18th century, the mass was at the bottom of a well and, at some other time, had been in a blast furnace. Nevertheless, besides its composition (~10% Ni) and remnant Widmanstätten features, several additional important textural and mineralogical features are still present. The dominant kamacite is accompanied by abundant plessite (~30 vol%) and primary schreibersite in various morphologies. Troilite and lesser amounts of chromite are found within the schreibersite. While schreibersite has not been significantly altered by heat, some of the troilite and most or all of the graphite present have been altered by the terrestrial heat treatment. Neither Neumann bands or fusion crust are reported by Buchwald (1975). A crust of terrestrial oxides is also present.

In spite of the sketchy records — many pertinent documents have been destroyed by wars — Elbogen has been deemed a witnessed fall by the meteoritical community. As such Elbogen is both the oldest and the most massive of the three recorded IID falls and the third most massive of the total of 22 recovered IID irons. While the largest portion of the mass (79 kg) is at the Naturhistorisches Museum in Wien (Vienna), significant amounts are also held by the Elbogen Rathaus (14 kg) and in the universities and museums of Prague (~13 kg).
