This study examines the earliest data of the history of the organ in Transylvania collected in the past one hundred and fifty years. A thorough examination proved that data, based on incomplete documentation, on erroneous hypotheses or conclusions, had been quite unprofessionally put into contexts to which they had no proven connection. Thus, legends regarding the first representation of an organ, the first organ, the earliest organ builders etc. appeared in the costume of historicity and were widely circulated among different authors.
