1400–1500: During the Renaissance it was fashionable for men to wear a number of chains, plaques, and pendants around their necks, and by the end of the 15th century the wealthiest men would wear great, shoulder covering collars inlaid with gems.

[9] In 1593 the English mile was redefined by a statute of Queen Elizabeth I as 5,280 feet, to tie in with agricultural practice.
In modern French, pendant is the gerund form of pendre ("to hang") and also means "during".
