The Jubilee of 1400 as chronicled by Giovanni Sercambi
The bull of indiction for the Jubilee of 1400, which was indeed celebrated, has never been traced. Giovanni Sercambi, a chronicler from Lucca (1348-1424), describes the events of that year and the great number of so-called “Whites” who flocked to the event. Members of the Confraternity of White Penitents (who probably originated in Provence) had established a penitential religious movement that by the end of the 14th century had spread through Italy and reached Rome
