Medieval monks lived in monasteries where they prayed, copied manuscripts, and performed various jobs. Boys who joined became novices and could become full monks by taking vows of poverty, chastity, and obedience. Monks wore tunics and cowls and had tonsured hairstyles. Their daily routines involved prayer, work, and meals in specific places like the church, fields, and refectory. Monasteries provided education, charity, and preserved knowledge through the monks' work.
