Eclessa was born in northern Greece and taken into slavery when she was captured by the cilician pirates. Taken to Italy, she was bought by a wealthy Roman. She spent years as a house slave before Spartacus' rebellion began.
Eclessa was a kind, but careful young woman. She did not enjoy her life as a slave, even though she was hardly punished, and was grateful to Spartacus when she was freed.
Eclessa was average height, thin and had short sandy colored hair.
