The poem was begun around 61 AD and several books were in circulation before the Emperor Nero and Lucan had a bitter falling out. Lucan continued to work on the epic – despite Nero's prohibition against any publication of Lucan's poetry – and it was left unfinished when Lucan was compelled to suicide as part of the Pisonian conspiracy in 65 AD. In total, ten books were written and all survive; the tenth book breaks off abruptly with Caesar in Egypt.
