PROBST Michael J. (cartographer) / PROBST Conrad (engraver), "Nova Tabula Totius Danubii, Gracia et Archipelagi", [Augsburg], 1789. Copper engraved map (58x50cm) of Greece and the area. Poor condition, previously folded, weak, restored in some places, few small wormholes, but overall a FOLIO map of a significant RARITY. After the death of Probst , in the mid 1780s, his three sons decided to publish two Atlases, one in Folio and one in oblong quarto, covering mainly Europe. None project was finally accomplished for several reasons (Babinski: Two Atlases by Probst). Although a first version of the small quarto-format maps was published with 20 maps around 1790 (a map of Greece had been published separately in 1797 / Karamitsos Auction 590, lot.6017), a very small number of the Folio format plates and maps finished and finally the high cost of the publication resulted to the end of this project ~1790-2. All the few - finally completed maps, mostly proofs, remained unprotected as separately issued. Very few survived and Probst disappeared around 1800. Not in Zacharakis, EXTREMELY RARE.
