What is "rectina"

Rectina was a friend of the Roman author Pliny the Elder. During the eruption of Vesuvius in 79 CE, Pliny received a message from her, which prompted him to set sail with galleys and a cutter to observe what was happening at closer range, and to attempt to rescue some of the people of the towns at the foot of the volcano.

Pliny's ships were driven back from the shore and Rectina was not rescued by Pliny the Elder. It is not documented whether she survived.
