In the olden days, the kings had scholars (like the nine gems in Akbar's court) who specialized in various things and also they helped in enriching art, culture, mathematics of the kingdom.
But to think of it, were they paid monthly or per visit? Were they salaried ? How did they find refuge at the king's court ? Was it through recommendations ?
What would they do coming to the court everyday (if they would)?
What if the king were a dung headed moron ? Would he have such scholars ?
Dancers, yes I can understand :-)
