Identifying an undescribed Danckerts atlas

Összefoglalás - 1997-ben a szegedi József Attila Tudományegyetem Földrajzi Tanszékeinek Könyvtárában felbukkant egy eddig ismeretlen Danckerts atlasz. A mű pontos leírása és meghatározása során kiderült, hogy ez egy rendkívül ritka, szép és értékes, ám sajnos hiányos, a XVII. század végéről származó munka. A kutatás folyamán felszínre került tények felhívták a figyelmet arra, hogy a mértékadó nemzetközi szakirodalomban is több módosításra szoruló adat és elképzelés található. Summary-In 1997 a heretofore unknown Danckerts atlas has come to light in the Library of Geography Departments of József Attila University (Szeged, Hungary). Scrutiny for identifying the work has resulted in establishing the volume as a remnant of an extremely rare and precious work from the late 17th century. The examination has also drawn attention to the necessary modification of recently accepted notions of the international carto-bibliography concerning the producing and publishing history of the Danckerts atlases

1783-1784. évi szélsőséges tél és a Maros jeges árvize = Severe winter of 1783-1784 and the iceflood on the Maros river

While during the severe winter of 1783-1784 a great flood event occurred on several major rivers of Western and Central Europe in February, three flood waves of rivers, scattered both in space and time, took place in Hungary from late December to the end of March when the extraordinary long winter of 1783-1784 finally ended up. Out of the three flood-waves, only the iceflood of the Maros river (Mureş in Romanian) and the flood of some of its tributaries ended up as a really damaging flood with further consequences in late December-early January, while the less-significant flood events caused by a sudden warm interruption in February and early March caused no great harm in the country. In the present study, after providing some background information, the actual flood events of late December and early January on the basis of contemporary sources are discussed together with the possible reasons concerning the origins and development of the damaging Maros-flood
