Final answer:
Medieval cycle plays were staged as part of religious festivals, mainly the Feast of Corpus Christi.
Step-by-step explanation:
While Greek plays were staged as part of the City Dionysia, honoring Dionysus, the god of wine and fertility, the medieval cycle plays were primarily staged as part of religious festivals. One of the most significant of these was the Feast of Corpus Christi, which became a focal point for the performance of cycle plays. These plays, like the famous Mystery and Morality plays, depicted Biblical stories and allegorical lessons in a dramatic form. Unlike their Greek predecessors, medieval drama focused on communicating Christian teachings and often moved through towns in pageant wagons as traveling performances, also known as Pageant Wagon tours.
