On this day in 1776, legend has it, the “Liberty Bell” rings out from the the tower of what is now known as Independence Hall in Philadelphia, summoning citizens to the first public reading of the Declaration of Independence.
The Liberty Bell is bronze. More specifically, it is 70% copper, 25% tin, with small amounts of lead, gold, arsenic, silver, and zinc. It weighs in at 2,080 pounds.
Even weightier is the inscription on the bell, from the Holy Bible, Leviticus 25:10:
PROCLAIM LIBERTY THROUGHOUT ALL THE LAND UNTO ALL THE INHABITANTS THEREOF LEV. XXV X.
