Chorégraphie - Durlach 209/210 -- two anonymous German Beauchamp-Feuillet choreographic-notation manuscripts at Badische Landesbibliothek Karlsruhe (BLB), shelfmarks Durlach 209 and Durlach 210, both catalogued [S.l.], 1701 (urn:nbn:de:bsz:31-863 + urn:nbn:de:bsz:31-972).

Two paired manuscripts copied from Feuillet 1700/1701 Paris publications, evidencing the German Baroque court-circuit reception of the Beauchamp-Feuillet system in the Durlach (Baden-Durlach) margraviate at the Karlsruhe Residenzschloss. Source: DATA/LIBRARY_OF_DANCE/ABBYY TXT/1720c-Choregraphie-209_(BLB).txt + 1720c-Choregraphie-210_(BLB).txt (4-5kB each; OCR recovers only repeating BLB digital-library watermarks and shelfmarks since the MS pages contain Beauchamp-Feuillet symbol-notation not ABBYY-recoverable). HISTORIC POSITION: paired German MSS dated 1701 — contemporaneous with the foundational Feuillet 1700 Paris print (LOC-1700-FEUILLET) and 17y post-Lully death (1687); slot in the Trichter 1742 Leipzig (LOC-1742-TRICHTER) → Behr 1709 → Pauli 1756 (LOC-1756-PAULI) → Lange 1751/1762 (LOC-1751-LANGE / LOC-1762-LANGE) → Petersen 1768 (LOC-1768-PETERSEN) German Baroque chain, providing the EARLIEST German Beauchamp-Feuillet manuscript-reception evidence at Karlsruhe.
