Jan Caramuel z Lobkovic. Otázky interpretace jeho původu

The article introduces a spectrum of interpretations pertaining to the kinship of famous scholar Juan Caramuel and the Bohemian noble Family of Lobkowicz that have been appearing since 1639 well to the present. Its purpose is to verify various interpretations and their sources and to confront them with facts presented in both hand-written and printed sources of various provenience and especially with the ones in the family archives of the House of Lobkowicz. The performed research has shown that the answer to the main question: Was Juan Caramuel really kindred with the Princes from the House of Lobkowicz and thus distantly also with many noble families from central and southern Europe? – has to be negative, although many ingenious theories stemming from misleading information used to genealogically connect him with these families in the past.
