Even though the function of blood and how it circulates in
the human body was discovered in 1615 by William Harvey, yet across the world,
every nation has had mysteries attached to blood from ancient times. At least
every culture has some kind of rite or ritual associated with blood, some of
which are practiced to date.
There are those who argue that the Biblical aspect of the
blood was borrowed from ancient Near East Semitic tribes, but that notion does
not have a strong basis. The Bible being the most reliable and accurate
ancient source of history1,
seems to have set in motion the universal reverential fear which emanates from
the shedding of blood (Gen 4:10). From here also stems the universal dignity
for human life.
