Final answer:
Monks were separated from the public areas of churches through the construction of walls and by locating monasteries in remote areas. This ensured a physical barrier and limited access for the public.
Step-by-step explanation:
During ancient and late antique periods, monks in monasteries were kept separated from the public areas of churches in various ways. One common method was to have a wall separating the monks' living quarters, known as monastic cells, from the public areas of the church. These monastic cells were lined along the wall, creating a physical barrier between the monks and the rest of the church. Additionally, monasteries were often built in remote locations or deserts, making it more difficult for the public to access them, further ensuring separation.
