In numbers, 318 is the numerical equivalent, via isopsephy (or gematria), of the words "Helios", the Greek name of the sun, and "Theta", the name of the 9th letter Θ of Greek alphabet, the letter being the Egyptian-Greco symbol of the sun, and "Eliezer", the chief servant of Abraham (the Judaic patriarch rescript of the Egyptian sun god Ra), a number which is symbolic of the diameter d of the divine solar sun god circle, with a circumference C of 1000, the ratio of which, via the formula for circumference of a circle:
yields an accurate 5-digit calculation of π.
In what is called ‘isopsephy’, a learning technique where early Greeks used pebbles arranged in patters to learn arithmetic and geometry, and to make coded ciphers, a technique passed along to the Hebrews, it is found that the following three words: Theta, Helios, and Eliezer, are each "numerically equivalent", according to what is called their "gematria value", to 318, which is the symbolic of the diameter of the so-called divine solar circle (as discussed below) or monad of the universe:
|Word/Name||Letter Values||Sum||Derived terms|
|Θ (Th-)||9 (≈ Ennead)||Theogony (Hesiod, 800BC), theology, thermal, thermo-, thermodynamics, think, thought, Thanatos|
|Θῆτα (Theta)||9 + 8 + 300 + 1||318||Name of the eighth letter of the Greek alphabet.|
|Ηλιος (Helios)||8 + 30 + 10 + 70 + 200||318||Greek name of sun; Heliopolis.|
|אֱלִיעֶזֶר (Eliezer)||318||Abraham's main servant, who he intended to leave all his wealth to.|
Theta, the name of the Greek letter Θ, which is equal to the number "9" in the Greek numeric system, which is symbolic of the 9 gods of the Heliopolis Ennead.
Helios is the Greek name of the sun, e.g. the Greeks referred to the main Egyptian sun god city as "Heliopolis", or city of the sun, a city defined the Egyptians by the following hieroglyph:
The hieroglyph shows, according to Wallis Budge (Ѻ), an obelisk with a cross on it, the water symbol or god Nun symbol, and a sun with a cross in it and or a sun inside of an eclipse, and a half-circle, which is bread., which is variously translated as: An, Anu, Junu, or Iunu. Junu is mentioned in the Pyramid Texts as ‘House of Ra’. Heliopolis is called On in Hebrew.
In the Bible (Pslam 16:9), it is stated that Abraham (aka Ab-Ra-ham), the Judaic rescript of the Egyptian sun god Ra, had a trained army of 318 servants; and that Eliezer, whose name is numerically equivalent to 318, was Abraham's main servant, who he intended to leave all his wealth to.
Mathematically, the number 318 is found to have several relations in respect to a circle with a circumference of 1,000 units.
Firstly, the ratio of 1/π which is:
Secondly, In Egypt, the Rhind Papyrus, dated around 1650 BC but copied from a document dated to 1850 BC, has a formula for the area of a circle that treats as: ≈ 3.16.
Thus, according to the standard formula for measuring the circumference d of a circle, according to its diameter:
we have the following formula for :
according to which, we have the following symbolism:
In 250BC, Archimedes proved, using a 96-side regular polygon, that π falls within the following range: 3.1408 < π < 3.1429. Likewise, Ptolemy, in his Almagest (150AD), gave a value for π of 3.1416.
The significance of the 1000, as the unit size of the so-called divine solar circle is said to represent the "divine monad", thousand equivalent, in the Greek ratio system, to "1", as David Fideler (1993) sees things:
- “Helios, 318, the Greek name of the sun, is derived from the ratio of the circle, for the reciprocal of π is .318. In other words, a circle measuring 1000 units in circumference (representing unity) will have a diameter of 318 units. In music, 0.666 is the string ratio of the perfect fifth, while 0.888 is the string ratio of the whole tone. The Greeks did not use the decimal point at all, and, in every instance where gematria values are based on mathematical ratios, the ‘decimal point’ has been moved over exactly three places. In other words, while we define these ratios in relation to ‘1’, we conclude that the Greeks defined these ratios in relation to ‘1000’, which represents the same principle, the monad or unity, the ineffable first cause.”

Alternatively, the significance of the 1000, according to Daniel Gleason (1998), is that it is a cypher or code for Jesus being a sun god:
- “The solar symbolism between the numbers ‘1000’ and ‘318’ was well known in ancient Greece. The product of the initials of Jesus Christ, in Greek Numerals (IX), is equal to the number ‘1000’. The solar symbolism in the name ‘Jesus Christ’ was apparent to anyone in antiquity who spoke Greek.”
- — Daniel Gleason (1998), “Theta – Helios (318), the Sun” 
In short, the product of the numerical equivalent, in the Attic Greek number system, of the initials of Jesus Christ (JC), or Ιησούς Χριστός (ΙΧ) in Greek, namely the product of "I" (iota), which equal 1, and "X" (chi), which equals 1,000.
On a related note, as pointed out by Leo Tavares (2020), is one divides the Greek numerical equivalent of Jesus Christ of 2368 (888 + 1480), this being a cypher name for the circumference C of the divine solar circle, by the Hebrew numerical equivalent of Jesus Christ of 754 (319 + 363), this being a cypher name for the diameter of the divine solar circle, we get a close approximation of π = 3.141.
The following are related quotes:
- “A circle with a circumference equal to ‘divine unity’, the number ‘1’ or any power of one such as 1x10x10x10 = 1,000 units, by calculation has a diameter that rounds down to 318 units. Consider the solar symbolism of this amazing discovery. In the 1st century AD, the value of π was supposedly not known to five decimal places. But if the 5th decimal place of π is set equal to the number ‘1’, the diameter of a circle with a circumference of 1000 units by calculation has a diameter equal to the gematria value of Helios (318) on each side of the decimal point!”
