Naumachia (Greek "sea-fight"), in ancient Rome, was a public spectacle, consisting of the representation of a naval battle, in which gladiators fought as they did in the amphitheatre. The first naumachia took place on a sheet of water in the Campus Martius, made for the purpose by Julius Caesar (46 B.C.).

“For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.”
Romans 8:38-39
