On 4th May 2023, a book presentation embedded in a small conference will take place in the Bartók Hall of the Institute for Musicology, Research Centre for the Humanities in Budapest. The event was originally scheduled for November 2022 and should have been part of the Festival of Hungarian Science. Due to the temporary closure of the Institute, we had to postpone it, but now we finally got the green light. The offer is indeed rich: there will be papers, with singing in between, a roundtable led by Miklós Földváry on the recently published Cantuale Paulinorum, a splendid little music manuscript from the early 16th century now kept in the Pauline monastery of Jasna Góra / Mons Clarus in Częstochowa, posters illustrating the results of the research group’s recent discoveries, and at the end a concert with the William Byrd Vocal Ensemble of Budafok conducted by Johanna Winnington-Ingram. It is a special pleasure that P. Róbert Antal Puskás OSPPE, Provincial of the Hungarian Pauline Order, will honour us with his presence.
