Blanket position, (slave position); when a blanket or cloak or covering of any sort is thrown over a slave girl she may not speak or rise; she must remain silent until the blanket is lifted by a free person.
I then threw the second blanket, the top blanket over her, covering her completely. When a blanket, or cloak, or covering of any sort, is thrown over a slave like this she may not speak or raise. She must remain as she is, silent, until the master, or some free man, lifts the covering away.
