The Greek alphabet has changed in many ways over the course of its existence. This is hardly surprising, given that the Greeks have been using it for nearly three millennia. One way in which it has changed is that some letters that used to exist in the Greek alphabet are now missing. Which letters were these, and what do we know about them?

The first letters of the Greek alphabet

To start, let us establish how the Greek alphabet acquired its letters in the first place. According to ancient Greek historians, the Greeks adopted the Phoenician alphabet after the arrival of a Phoenician prince named Cadmus. Archaeology confirms that this occurred at some point in the ninth century BCE.

The Phoenician alphabet was composed of only consonants. When the Greeks adopted it, they modified it to include vowels as well. This was a major step forward in the development of writing.

According to Plutarch, a Greek historian of the first century CE, there were originally sixteen Greek letters. However, Hyginus, an earlier writer, reports that there were originally eighteen.

In reality, it appears that neither version is correct. Physical evidence in the form of ancient inscriptions reveals that the earliest Greek inscriptions made use of all twenty-two letters in the Phoenician alphabet. However, four of these were for sounds which did not exist in Greek, so they were modified into vowels.

Perhaps this is where Hyginus’ idea of eighteen original letters comes from, being a distorted memory of the eighteen original consonants. In any case, the total number of letters in the Greek alphabet increased over time.

Why are there some missing letters?

Some of the letters used in ancient Greek inscriptions are simply not in the modern Greek alphabet. Why is this? Simply put, the reason is that the Greek language itself has evolved over time, and the alphabet exists to comply to the needs of the language rather than vice versa.

Additionally, different dialects of the Greek language existed within the Greek world at the same time. Therefore, the needs of each dialect would not necessarily be covered by the same letters.

In the late fifth century BCE, the alphabet used by the Ionian Greeks became the official, standardized alphabet of Athens. Over the following century, it then replaced the local alphabets of other Greek regions. By that time, the dialect of the Ionian Greeks was such that their alphabet did not make use of all the letters that had once been in use. Rather, their alphabet used just twenty-four letters. Hence, what were the letters that the Greek alphabet used to have but no longer does?

Digamma

One of the most famous lost letters of the Greek alphabet is Digamma. This had the following form:

Ϝ

It is superficially very similar to the modern F, but the sound was completely different. It was essentially the modern w sound. In fact, the original name for this letter was ‘wau’, taken directly from the Phoenician name for this letter.

San

Another lost letter is San. This had the following form:

Ϻ

Like Digamma, this looks almost identical to a more familiar letter. In this case, it looks just like the modern letter M. However, like with Digamma, the sound indicated by this ancient letter was completely different. Unlike the modern M, the ancient San, or Ϻ, was used to indicate an s sound. This fell out of use in favor of the alternative letter Sigma, written as Σ.

Koppa

Another letter that is no longer in use is Koppa, which had the following written form:

Ϙ

This is similar to the modern Q in the English alphabet, and that is no coincidence. Koppa was still part of the Greek alphabet when the Latins adopted it, which led to this letter eventually becoming the Q in English. The English alphabet originated from the Romans. The sound Koppa indicated was a k sound. It eventually fell out of favor in Greek, being replaced by the alternative letter Kappa, written as Κ.

Sampi

This next letter is called Sampi. It was written as:

Ͳ

This is very similar to the modern T, but it is unrelated. That modern letter comes from the ancient Greek Tau which, of course, had a t sound. In contrast, the ancient Greek Sampi had some kind of s or sh sound, although the exact vocalization is unknown. In any case, it fell out of favor when this sound was no longer used.

Ancient Greek scientist Erasistratus (300-250 B.C.) is credited with being among the first human lie detectors. He devised a specific technique to read a person’s physical response so as to spot when an individual was lying.

While in Alexandria, Egypt, he is said to have proven Prince Antiochus was desperately in love with his father’s new wife, Stratonice. He noted how his pulse increased significantly whenever the queen’s name was mentioned, despite his insistence that he did not have the hots for his stepmother.

Love-struck, he fell ill with passion and chose to pine away in silence. The physicians were unable to discover the cause and nature of his disease.

Erasistratus himself was at a loss at first, until, finding nothing amiss about his body, he began to suspect that it must be the man’s mind that was diseased and that he might perhaps be in love.

Erasistratus confirmed his conjecture when he observed that the skin of Antiochus grew hotter, his color deeper, and his pulse quicker whenever Stratonice came near him, while none of these symptoms occurred on any other occasion.

The Greek physician eventually told the father, King Seleucus, that his son’s disease was incurable, for he was in love with the monarch’s wife and that he chose to die rather than to disclose his secret.

According to the anecdote, Seleucus not only gave up Stratonice, but also resigned to his son several provinces of his empire.

Erasistratus founded school of anatomy in Alexandria

Erasistratus, along with fellow physician Herophilus, founded a school of anatomy in Alexandria where they carried out anatomical research.

He is credited for his description of the valves of the heart. He also concluded that the heart was not the center of sensations. Instead, he said, it functioned as a pump. He was among the first to distinguish between veins and arteries, believing that arteries were full of air and carried the “animal spirit” (pneuma).

Together with Herophilus, he is credited by historians as the potential founder of neuroscience due to his acknowledgment of nerves and their roles in motor control through the brain and skeletal muscles.

Furthermore, Erasistratus is seen as one of the first physicians/scientists to conduct recorded dissections and potential vivisections alongside Herophilus.

The two physicians were said by several Roman authors, notably, Augustine, Celsus, and Tertullian, to have performed controversial vivisections on criminals to study the anatomy and possible physiology of human organs while they were in Alexandria.

Stoicism, was one of ancient Greece’s philosophical movements founded by Zeno of Citium in Athens in the early 3rd century BC.

Stoicism is a philosophy of personal ethics informed by its system of logic and its views on the natural world. For the Stoic, virtue alone is sufficient for human happiness.

For Stoics, emotions like fear, envy, passionate love were merely false judgements and the sage, a person who had attained moral and intellectual perfection, would not be touched by them.

It is a philosophy of life where the individual maximizes positive emotions, reduces negative emotions, and helps him or herself hone their virtues of character.

The name derives from the porch (stoa poikile) in the Agora at Athens decorated with mural paintings, where the members of the school congregated, and their lectures were held.

Birth of Stoicism, one of ancient Greece’s philosophical movements

The philosophy of Stoicism was originally known as “Zenonism” after the founder, Zeno of Citium.

Zeno ended up in Athens after his ship wrecked near the city. He was not a philosopher, but he turned his misfortune into an opportunity by studying all the philosophical resources available in the city.

He sat in on lectures from the other schools of philosophy (e.g., Cynicism, Epicureanism) and eventually started his own.

However, the Stoics did not believe that the founders were perfectly wise. In order to avoid their philosophy becoming a cult of personality, they chose to name it Stoicism after the place they were meeting, the stoa poikile of the Agora.

Zeno’s ideas developed from those of the Cynics, whose founding father, Antisthenes, had been a disciple of Socrates. Zeno’s most influential follower was Chrysippus, who was responsible for molding what is now called Stoicism.

Other prominent Stoics included Cleanthes of Assos, Panaetius of Rhodes, Aristo of Chios, Posidonius of Apameia, Diodotus, and others.

Later, Seneca, Epictetus, and Roman emperor Marcus Aurelius ushered Stoicism to the Roman world. The philosophy flourished until the 3rd century AD.

Stoic Philosophy

According to Stoicism, the path to eudaimonia (happiness) is embracing and accepting the moment as it presents itself by not allowing oneself to be controlled by the desire for pleasure or by the fear of pain.

The Stoic must use his or her mind to understand the world and to do one’s part in nature’s plan by working together and treating others fairly and justly.

The Stoics are especially known for the teaching “virtue is the only good” and that people must lead a virtuous life to be accomplished and complete human beings.

External things—such as health, wealth, and pleasure—are not good or bad in and of themselves but have value as “material for virtue to act upon.”

The Stoics also held that certain destructive emotions, such as fear or jealousy, resulted from errors of judgment, and they believed people should aim to maintain a prohairesis (will) that is “in accordance with nature.”

To live a good life, a person had to understand the rules of the natural order, Stoics believed, since everything was rooted in nature.

For many Stoics, virtue is sufficient for happiness. Thus, a sage would be emotionally resilient to misfortune and would therefore be considered truly free.

According to Stoics, people don’t truly have control over many things and situations in life. Therefore, they believe that worrying about things outside of their control is unproductive, or even irrational for a person who wants to attain tranquility and happiness.

Stoics differentiate between what is and what is not under human control and do not waste energy and thoughts over uncontrollable adverse events.

Where many people worry endlessly about things out of their control, the Stoics believe they should expend their energy in thinking of creative solutions to problems, rather than the issues themselves.

Stoicism is not about having a set of beliefs or ethical claims. It is not a school of philosophy that is separate from everyday life.

The stoic must continuously practice and train (“askesis”). Stoic philosophical and spiritual practices include logic, Socratic dialogue and self-dialogue.

Influence of Stoicism on Christianity

The virtuous life of the Stoic has resemblances to a life led by a good Christian. Stoic writings such as “Meditations,” by Marcus Aurelius, have been highly regarded by many Christians throughout the centuries.

The Greek term for word is logos. The Greek philosopher Heraclitus used logos (the word) to explain what he saw as the universal force of reason that governed everything.

In the 5th century BC, Heraclitus said that all things happen according to the Logos. The Stoics also believed in the Logos, along with the notions of conscience and virtue.

A few centuries later, Greek-speaking Jews came to view the Logos as a force sent by God. In the Gospel of John, Jesus is referred to as the Word — “and the Word of God was made flesh and dwelt among men.”

The apostle Paul is known to have met with Stoics during his stay in Athens. In his letters, Paul reflected on his knowledge of Stoic philosophy, using Stoic terms and metaphors to assist new converts in their understanding of Christianity.

Both Stoicism and Christianity teach a person the importance of training their mind and body to be disciplined.

Both encourage the elimination of passions and inferior emotions, such as lust and envy, from one’s life, so that the higher possibilities of one’s humanity can be awakened and developed.

“If you want to be perfect, go, sell your possessions and give to the poor, and you will have treasure in heaven,” Jesus preached.

Similarly, as Seneca wrote, “We must give up many things to which we are addicted, considering them to be good.”

The Eastern Orthodox Church and Oriental Orthodox Church accept the Stoic ideal of dispassion to this day, as do ascetics all over the world.

Stoicism today

Daily Stoic, How to be a Stoic, The Modern Times Stoic, Modern Stoicism, Traditional Stoicism: these are only a handful of the websites that hail the importance of—even the need for—Stoicism in the 21st century.

Is it possible, though, for today’s man to embrace a philosophy that teaches indifference to material things and possessions in a ruthlessly material world?

An intellectual and popular movement called Modern Stoicism began at the end of the 20th century which is aimed at reviving the practice of Stoicism.

However, before that, Stoic philosophy served as the original philosophical inspiration for modern cognitive psychotherapy, particularly as mediated by Dr. Albert Ellis’ Rational-Emotive Behavior Therapy (REBT), the major precursor of Cognitive Behavioral Therapy (CBT).

In the original cognitive therapy treatment manual for depression by Aaron T. Beck et al., it is stated, “The philosophical origins of cognitive therapy can be traced back to the Stoic philosophers.”

A well-known quotation from the “Enchiridion” of Epictetus was taught to most clients during the initial session by Ellis and his followers: “It’s not the events that upset us, but our judgments about the events.”

This subsequently became a common element in the socialization phase of many other approaches to CBT.

Ryan Holiday’s The Obstacle is the Way; Stoicism—A Stoic Approach to Modern Life, by Tom Miles; Modern Stoicism, by Steve Brooks; and Modern Stoicism—How to Be a Stoic in the 21st Century, by Stephen Ryan are some of the books on Stoicism that have been published recently.
