January 24, 76 AD, Roman Emperor Publius Aelius Hadrianus Augustus, known for his wall, was born on this day in history. But the History Channel’s lead story is: January 24, 1935, First Canned Beer Goes on Sale. Haha [amusement added].
According to Wikipedia:
In 122 he initiated the construction of Hadrian’s Wall. The wall was built, “to separate Romans from barbarians,” according to the Historia Augusta (Augustan Histories).
