Candide by Voltaire Chapter 18 Page 8

Twenty beautiful young virgins in waiting received Candide and Cacambo on their alighting from the coach, conducted them to the bath and clad them in robes woven of the down of hummingbirds; after which they were introduced by the great officers of the crown of both sexes to the King's apartment, between two files of musicians, each file consisting of a thousand, agreeable to the custom of the country.

When they drew near to the presence-chamber, Cacambo asked one of the officers in what manner they were to pay their obeisance to His Majesty; whether it was the custom to fall upon their knees, or to prostrate themselves upon the ground; whether they were to put their hands upon their heads, or behind their backs; whether they were to lick the dust off the floor; in short, what was the ceremony usual on such occasions.
