Marching to War
Marcellus stood in his villa dressed in nothing but a subligoria, as two of his many slaves slowly equipped his clothing and armor onto his body. Like any other morning, the first thing he did was get dressed. However, In these treacherous times, it was better to be safe than sorry and because of this; he treated his daily life as if he were in an active war zone. Which meant he war his armor from the second he got up in the morning, until the moment he went to bed.
The two young slave women were completely nude as they began to dress their master. Marcellus had always instructed his slaves in a way that cemented his authority. That was what he referred to as the first law of the household.
Essentially, this meant that Marcellus, as the head of the house, was the first to bathe in the morning, the first to get dressed, and the first to eat. Thus, despite already being awake before him, the girls had yet to put on any clothes themselves.
