Do you realise that left handedness was the sign of the devils disciples?
The Latin word for "LEFT" was "SINISTERI" which is where our word sinister comes from, meaning evil and un-natural.
The word for "RIGHT" was "DEXTERI" which is where dextrous comes from, meaning good and proficient.
Even back in the early 1960's at my school, children who were left handed were forced to write with their right hands.
Theres a brilliant scene in the old film Carry On Cleo, where Sid James is marching a troop of roman legionairres, calling out "sinister, dexter, sinister, dexter"
