Final answer:
Reliquaries and the objects they hold both contain religious relics. They are particularly crafted containers adorned with precious materials to house and protect sacred objects with significant spiritual and economic importance during medieval times.
Step-by-step explanation:
Reliquaries share a special connection with the objects they hold; both contain religious relics. A reliquary is a specially designed container that houses sacred relics, which are often pieces associated with the body or belongings of saints or other venerated figures in religious traditions.
During medieval times, the importance of relics was significant not only for their spiritual value but also for their role in drawing pilgrims to churches, which could have economic benefits for the region. Due to their spiritual and economic value, a black market of fake and stolen relics emerged alongside the official trade of these sacred items.
