We tend to think of traffic analysis as a modern technique, but it's
actually quite old. Here is a message from a spy, observing the
activities of two of (English Queen) Elizabeth I's courtiers, whom he
suspected of trying to manipulate her successor:
many secret meetings are made between them, where, after serious
consults, they dispatch messengers and packets of letters, this
sometimes twice in a week.
This was in 1602.
