Gematria

Gematria is a system of numerology that assigns numerical values to names, words, or phrases. This is done by reading letters as numbers or by using an alphanumeric cipher. In these systems, every letter in an alphabet has a standard value. A single word can sometimes yield several different values depending on the cipher used. By adding these values together, people find a total sum for a text. This allows them to compare different words that share the same numerical result.

This practice helps people find hidden connections between ideas through mathematical patterns.

The mechanism of gematria involves converting phonetic letters into numerical values. Once the letters are assigned numbers, they are added together to create a sum. In Hebrew gematria, this involves reading words as numbers instead of sounds. For example, the Hebrew word for wine, "yayin," has a value of 70. This is calculated by adding the values of the letters: yod (10), yod (10), and pe (50). Interestingly, the word for secret also has a value of 70. This mathematical link suggests a connection between the two concepts in certain traditions. Another short example is the word "chai," meaning life, which sums to 18. This has made 18 a lucky number in many Jewish cultures.

There are several distinct types of these systems across different cultures. One major type is isopsephy, which is the Greek predecessor to gematria. Another type is the Arabic abjad system, which uses specific numerals for letters. There is also English gematria used in later centuries. In early Jewish sources, the term could also refer to other methods like atbash. These different systems all rely on the same basic idea of linking language to math. They vary based on the specific alphabet and the rules of the cipher being used.

The history of these practices stretches back thousands of years. The first documented use of this method is found in an Assyrian inscription from the 8th century BCE. King Sargon II commissioned a wall in Khorsabad that was 16,283 cubits long. He chose this specific length to match the numerical value of his own name. In Greece, the Milesian system developed in the city of Miletus. Aristotle noted that isopsephy was part of the Pythagorean tradition from the 6th century BCE. This Greek system was common during the reign of Alexander the Great. It was later officially adopted in Egypt under Ptolemy II Philadelphus in the 3rd century BCE.

Significant numbers appear frequently in historical and religious texts. In the Hebrew tradition, the word "HaSatan" has a value of 364. This led to the belief that the Satan has authority to prosecute Israel for 364 days of the year. In the Islamic tradition, the phrase "Bismillah al-Rahman al-Rahim" has a value of 786 in the Abjadi system. This number is so significant that it appears in modern pop culture and music. In the New Testament, some scholars suggest the number 153 in the Gospel of John is a gematria reference. Others look at the number 666 in the Book of Revelation. Some historians believe this number corresponds to the Hebrew transliteration of the name "Neron Kaisar."

Notable examples of gematria can be found in many ancient writings. The text 3 Baruch uses the number 360 to represent a snake. This is because the Greek word for snake, "drakon," equals 360 when transliterated into Hebrew. The text also uses the number 409,000 for giants that died in the Deluge. This comes from the numerical value of the Greek word for "deluge." In the Epistle of Barnabas, written between 70 and 132 CE, the number 318 is used. This number is linked to the servants of Abraham and the Greek name for Jesus. These examples show how deeply math was woven into ancient storytelling.

While many find these patterns interesting, some thinkers have criticized the method. The philosopher Iamblichus offered three main arguments against it. First, he noted that different letters can have the same value but opposite meanings. Second, he argued that the shapes of letters change over time, making them unreliable. Third, he worried that math allows for too much flexibility. He believed that by using addition or division, one could make any number fit any idea. Despite these critiques, gematria remains a major part of Jewish Kabbalah and various other belief systems.
