Nine • 9
Neuf - Nueve - Dokuz - Devet - Εννιά
The second perfect number in the first decade. The nine muses. The triple triad, completion, fulfillment, beginning and end, the whole thing, the earthly paradise. From a numerological point of view the nine is a particularly interesting number: as the sum of a multi-digit number, that contains a nine, is always the sum of the remaining figures (Example: 199 = 19 = 10 = 1), i.e. when calculating the sum, one can strip all nines.
Also, 9 is the only number whose multiplication results have always 9 as their sum of digits. This number always remains itself. Zeus' Deucalion's flood lasted nine days and nine nights and erased the first mankind – only Deukalion and Phyrra survived. According to the current state of science our solar system has nine planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. The human pregnancy lasts 9 months.
