A hundred and ten reduces to two. Its firmest traditional meaning is Egyptian: a hundred and ten years was the ideal span of a good and blessed life in ancient Egypt, the age wished upon the righteous in the texts, and the age at which the best-favoured were said to die. The Hebrew Bible preserves the same figure in two Egyptian-flavoured deaths: Joseph, who rose to power in Egypt, dies at a hundred and ten, and so does Joshua, whose formative years belonged to the Egyptian generation, a detail scholars read as an echo of the Egyptian ideal.
In chemistry, a hundred and ten is the atomic number of darmstadtium, first made in 1994 at the GSI laboratory near Darmstadt, Germany, and named for the city.
A hundred and ten factors as 2 x 5 x 11 and carries 8 divisors in all. Summing its proper divisors gives only 106, short of the number itself, which places it among the deficient numbers in the same classical scheme.
The whole apparatus of digit-reduction numerology is a twentieth-century invention rather than an inheritance from antiquity. Mrs. L. Dow Balliett published the first systematic version, The Philosophy of Numbers, in 1908, fixing the letter-to-number chart still used today and ruling that eleven and twenty-two must stand as master numbers rather than reduce further; her colleague, the physician Julia Seton, is credited with coining the word numerology itself around 1912.
