Although not directly interest, but in similar vein:
There was once a so called fair profit rate of 4% in the middle ages and early modern age, in Hungary. Greek wine traders operating there featured the number 4 on their seals and ornaments of their houses. (They were also often tried for violating this rule)
In those ages of course there was no constant inflation in the current sense, gold standard was used for payments, etc.
