"It was natural enough, in the circumstances, for Tafa to have addressed Phoebe as "Mistress." As Tafa was currently subject to us, and Phoebe was with us, this put Phoebe in a position of de facto priority to her. For example, in a group of female slaves, for example, in a pleasure gardens, a fortress or a tavern, there will usually be a girl appointed First Girl. Indeed, if there is a large number of slaves, there are sometimes hierarchies of "first girls," lower-level first girls reporting to higher level first girls, and so on. The lower-level slaves will commonly address their first girl as "Mistress."

Thus, in some situations, the same girl may be first girl to certain girls and be subordinated herself to another, on a higher level, whom she will address as "Mistress." Sometimes a hierarchy is formed in which girls are ranked in such a manner that each must address the girls above her as "Mistress." More commonly, it is only the lowest slave, usually the newest slave, who must do this with all the others, whereas the others will address only their first girl as "Mistress", and, of course, any free woman whom they might, to their risk, or peril, encounter."---Magician, p. 123
