The term “falus” refers to a historical currency unit used in various parts of the Islamic world, particularly in North Africa and the Middle East. The falus was a copper coin, often featuring Islamic calligraphy, geometric designs, and sometimes the names of rulers or minting authorities. These coins were issued by various Islamic dynasties and empires and were often of low denomination, used in everyday commerce.
In the context of the Roman Empire, “falus” is often associated with the Falsus or Follis, a bronze coin denomination that was primarily used during the later Roman Empire. These coins were typically larger and heavier than the smaller denominations and were characterized by their bronze composition and relatively low value.
