The forms
saecla,
saeclorum etc. were normal alternatives to the more common
saecula etc. throughout the history of Latin poetry and prose. The form
saeculorum is impossible in
hexameter verse: the
ae and
o are long, the
u short
by position. The word
seclorum does not mean "secular", but is the
genitive (possessive) plural form of the word
saeculum, meaning (in this context) generation, century, or age.
Saeculum did come to mean "age, world" in late, Christian Latin, and "secular" is derived from it, through
secularis. However, the adjective "secularis," meaning "worldly," is not equivalent to the genitive plural "seclorum," meaning "of the ages." The motto
Novus ordo seclorum was translated and added to the seal by
Charles Thomson, a Latin expert who was involved in the design of the Great Seal, as "A new order of the ages." Thomson said it was to signify "the beginning of the new American Era" as of the date of the
Declaration of Independence in 1776, which was depicted in
Roman numerals at the base of the pyramid on the seal. == See also ==
