Slaves in the Late Roman Army

[Frank]

Okay, so all seems doable. Nice. I would still like to know what happened to a slave whose master died while fighting, if anyone could answer that.

He becomes inheritance. No matter how his master dies. If the master has not written down his will, the close relatives will inherit. Roman law was not that different about this case. Soldiers sometimes constituted comrades as heirs. The slave could be freed in the will.

Regarding prostitution, I see no reason, why a slave should not spend money on it. He can use his peculium in any way he wants, as long as his master is not explicitly against it.

Slaves could marry (contubernia), but just with permission of the master(s). But the law changed often during the centuries, especially if the bride was a free woman. Now it becomes a bit complicated. Let him become a freedmen before he marries to avoid issues. Or let him deal with it like a legionary. Legionaries (until Septimus Severus) could not marry. They just lived together with women until dismissal.
