Tommaso Daineri levelei II. Ulászló csillagászati műszereiről

Combining Italianate and science historical interests, the two authors present for the first time in Hungarian trans- lation the descriptions of the astronomical instruments of King Wladislas II in the original contexts of letters. We have compared the descriptions with similar contempo- raneous instruments, using the results and databases of the research literature of astronomy history. Our work was helped by several factors: photocopies of reports by Modenese envoys got incorporated in the system of the electronic Archival Portal of the Hungarian National Ar- chives within the frames of the Vestigia research project, and Elena Ferrazzi published the letters of Daineri in her dissertation of 2021.
