10 Strange Laws and Customs of Ancient Rome

10 Strange Laws and Customs of Ancient Rome

Long before modern medicine or modern law, Rome had its own systems for both — some surprisingly close to logic, others nothing like it at all.

An Unusual Pregnancy Test

Ancient Roman medical practice reportedly included a folk pregnancy test in which a woman would insert a clove of garlic and check the next morning whether her breath carried its scent — the theory being that if it didn't, a pregnancy was blocking the passage. It had no real medical basis, but it reflects how far ancient physicians reached for diagnostic methods without modern tools.

The Cult of Mithras

Mithraism, a mystery religion popular among Roman soldiers from roughly the 1st to 4th centuries CE, centered on the god Mithras. Some scholars believe its rituals may have included a symbolic bull sacrifice, with initiates positioned beneath the animal — though the exact nature and universality of this practice remains debated among historians.

The Roman Triumph

A Roman triumph was a lavish public ceremony celebrating a victorious military commander. As part of the ritual, the triumphant general painted his face red, symbolically associating himself with the god Jupiter for the day.

Beauty Standards

Roman beauty standards for women included complete body hair removal, often performed by slaves at public baths, and the use of lead-based whitening cosmetics — a practice now understood to have caused slow poisoning in regular users, unbeknownst to Romans at the time.

Dinner Etiquette and Enslaved Household Members

At formal Roman dinners, guests customarily brought a napkin to wrap up leftover food to bring home as a gift for a household slave — a practice called apophoreta, considered a firm social obligation.

Dancing Was Restricted

Public dancing by ordinary Roman citizens was considered scandalous and was generally reserved for trained performers or religious ceremonies conducted by designated priestesses, reflecting Rome's formal distinctions around public conduct.

The Vestal Virgins

Vestal priestesses were selected to maintain Rome's sacred fire and lived under lifelong vows including chastity. Despite the demanding, restrictive nature of the role, becoming a Vestal Virgin was considered one of the highest honors available to a Roman woman.

Ancestor Death Masks

Wealthy Roman families displayed wax death masks, called imagines, of ancestors going back multiple generations in their homes, often lit with small lamps at night — a practice reflecting the importance of lineage and status in Roman society.

Protective Symbols

The Romans commonly used phallic imagery, known as a fascinum, as a protective and good-luck symbol, displaying it outside homes and in jewelry. This is the origin of the modern word "fascination." Unlike many later cultures, Roman society did not generally treat this imagery as inherently shameful.

Patria Potestas

Under Roman law, a father held significant legal authority over his household, known as patria potestas, which historically included the power to decide whether a newborn child would be raised — a practice historians say was exercised with some frequency, though the exact extent varied across Roman history and is debated among scholars today.
