<P> The origins of the 15 , 30 , and 40 scores are believed to be medieval French . The earliest reference is in a ballad by Charles D'Orleans in 1435 which refers to quarante cinque ( which gave rise to modern 40 ) and in 1522 there is a sentence in Latin `` we are winning 30 , we are winning 45 '' . The first recorded theories about the origin of 15 were published in 1555 and 1579 . However the origins of this convention remain obscure . </P>
