Another strange find on Google Books:
Natural History in Romanian in... Cyrillic script! We are not talking about the Moldovian Soviet Socialist Republic: rather, the year is 1837 and the country is [Western] Moldova (Iași - Ешiй) under the Ottoman domination!
The language of the work is described as "Лимба Ромънѣскъ" (Romanian language) in Romanian, or "langue Valaque" Wallachian language) in French.
Apparently, a rather old-fashioned looking Cyrillic alphabet was the standard for Romanian until ca. 1860.
