Jubilees of 1390 and 1423
In virtue of an ordinance of Pope Urban VI, it was proposed to hold a jubilee every 33 years as representing the period of the sojourn of Christ upon earth and also the average span of human life. The next jubilee was held in 1390, and the Basilica di Santa Maria Maggiore was added to the list. The visits to these four churches has remained as one of the conditions for gaining the Roman jubilee indulgence.
