Edith wollte noch ergänzen:
...the earliest cite to mention a specific game or sport
is from 1594 and reads: "But if thou shalt vouchsafe to recall so
vnskilfull an archer againe into the fieldes, I may perhaps winne
a bet, that shall pay for the losse of a rubber." But it isn't
clear from that whether the "rubber" also refers to archery, or
implicitly to some other game or sport that they were betting on.
In 1599 there's one that refers to "bowles".
Hier wird rubber also noch vor Herrn Dr. Condom oder auch der Erfindung des Kartenspiels Bridge erwähnt.
