With thanks to Pete Laberge who suggested this historical figure to me!

20131003-082843.jpgMansa Musa I, the richest man of all time,
Makes Bill Gates look like he’s made just a dime!
The current world’s richest man is Carlos Slim,
But he only places 22nd alongside him,
Slim has a paltry $68 billion,
This is nothing alongside Musa’s gerzillion!
Adjust his fortune, in line with inflation,
It’s $400 billion, no exaggeration!
On a pilgrimage to Mecca in 1324,
He took riches with him never seen before.
500 stewards went with him upon this Hajj,
Each carrying a staff of gold as their Musa badge,
When Musa passed through Cairo, he gave so much gold away,
That the economy suffered for 20 years from that very day!
He raised mosques and madrasas* in Timbuktu,
This man knew how to spend his rich revenue!
There were 400 cities in Mali by the time he died,
And his glittering reputation was ratified.
