In 2457 BC work gangs began quarrying at Tura For the next 14 years they ferried stone across the flooded valley In what year was the process completed?
BC means Before Christ. Intead of counting up the years like you do in AD (AD is what we count in now, e.g. 2001, 2002, 2003), you count backwards till you get 0 BC, whi…ch is when Christ was born. After 0 BC starts 1 AD then 2 AD etc. So basically, if you started in 2457 BC, and finished 14 years later, you would finish in 2443 BC. (MORE)
