The end of October 2022 is dedicated to four bronze doors in Sicily. At the cathedral of Monreale, we will document the doors of Barisano di Trani (who also made the doors of Ravello and Trani) and Bonanno, who is responsible for the doors in Pisa. Bonanno’s door is the largest of all bronze doors studied: with a hight of almost 8m, it will be challenging to carry out analyses at the very top of the door (happily, non of us suffers from vertigo). In Palermo, we will document and analyses the two massive bronze doors at the Cappella Pallatina, Palazzo Reale.
