Obolus

What is Obolus?

An obolus (also known as an obol or obole) refers to two distinct historical units of currency or weight:

• Ancient Greece: An obol was an ancient Greek coin or unit of weight equal to 1/6 of a drachma. In the Athenian system, it served as a fundamental subdivision of the currency.¹²
• Medieval France: An obole was a coin equivalent to a half denier, which was also referred to as an obolus.³

The term derives from the Latin obolus and the Greek obolós or obelós. While the word appears in Old English, its usage in modern contexts is primarily a result of later learned adoption.¹

What was the drachma used for in ancient Greece?

The drachma was a silver coin that served as a primary monetary unit in ancient Greece. Dating back to the mid-6th century BCE, its name is derived from a Greek verb meaning “to grasp,” reflecting its original value as equivalent to a handful of arrows.⁴

As Athens rose to commercial prominence in the 5th century BCE, the Athenian drachma became the foremost currency of the Greek world. Following the conquests of Alexander the Great, it became the standard monetary unit across the Hellenistic world. The coin was highly influential in trade, with its silver tetradrachms (four-drachma coins) being widely accepted and imitated as far away as Egypt, Arabia, and Persia.⁴⁵

The drachma functioned as a base unit within a larger system:

• 1 drachma = 6 oboli
• 100 drachmas = 1 mine
• 60 mine = 1 Attic talent⁴

Why were coins placed in the mouths of the dead in Greek mythology?

In Greek mythology, coins were placed in the mouths of the deceased to serve as payment for Charon, the ferryman of the underworld.⁷⁸

According to popular belief, the souls of the dead had to cross the marshy river Styx (or sometimes the Acheron) to reach the realm of Hades. Charon, a minor deity depicted as a morose and grisly old man, was responsible for ferrying those who had received proper burial rites across these waters. The coin placed in the corpse’s mouth acted as the fare required to secure passage on his ferry.⁷⁸

This practice highlights the importance of burial rites in ancient Greek culture, as those who were not properly buried or lacked the means to pay the ferryman were often depicted as unable to cross into the afterlife.⁷⁸⁹

How did ancient Greek trade systems function?

Ancient Greek trade systems evolved significantly over time, transitioning from individual aristocratic ventures to complex, empire-wide networks.

Early Trade and Individual Enterprise

During the early Archaic period, there were no formal “trade leagues.” Instead, commerce was driven by entrepreneurial aristocratic individuals who leveraged personal networks of guest-friendships to facilitate exchange across distant regions. These traders often hailed from areas with limited arable land, such as the island of Aegina, which necessitated trade for survival.¹⁰

The Role of the Agora

Within the city-state, the agora served as the central hub for commercial, social, and judicial activity. Located near the city center or harbor, these open spaces were often surrounded by stoae (covered colonnades) that housed shops. In highly developed cities like Athens, trade was organized by quarter, and officials known as agoranomoi were appointed to regulate commercial conduct.⁴¹¹

Hellenistic Expansion and Standardization

Following the conquests of Alexander the Great, trade underwent a massive transformation:

• Monetary Integration: The adoption of the Attic standard for gold and silver coins reduced the complexities of money-changing across the empire.¹²
• Infrastructure: The integration of city-states into a single empire removed trade barriers, while the expansion of routes opened access to China, India, and East Africa.¹²
• Specialization: Trade focused on essential commodities, including metals (tin, copper, iron), grain, olive oil, and textiles.¹²
