After Octavian had succeeded in capturing the Egyptian Queen Cleopatra VII in her Mausoleum in Alexandria she was strictly guarded by Epaphroditus and some other guardians under his command, first in her Mausoleum, then in the palace (early August 30 BC).
But the Queen was able to feign her will to live so that Epaphroditus observed her less strictly.
Then she gave him an urgent sealed letter that he should deliver personally to Octavian and while he was absent she succeeded in committing suicide.
[2] Some modern historians do not believe this ancient tradition, but assume that Octavian had no interest that Cleopatra survived.
Because the Emperor knew that she rather wanted to die than to be presented in a triumph he ordered Epaphroditus – according to this theory – to control Cleopatra only apparently, so that she could easily commit suicide.
