Now you might remember the names of the seven wonders, but do you know why 'seven' was such an auspicious number in ancient cultures?

In the ancient cultures, the number seven was a very important one, and it was mostly seen as a number of perfection and completeness. This is not the case in only one ancient civilization, but it can be found in multiple ones, Mesopotamia, Ancient Greece, Israel/Judea, Ancient Egypt etc. This led to a situation where this number has been heavily used when it came to important things, be it something connected with the Gods, with important hings in the daily lives, with the nature, with selection of things.

in griswold v. connecticut (1965), the supreme court ruled that a state's ban on the use of contraceptives violated the right to marital privacy.
