Virgil, Aeneid II.6

Melphi

Melphi speaks

et quorum pars magna fui.

The priest translates

«and in which I played a great part.»

And interprets

This line tells you something simple: the story you are about to tell is your story too. Perhaps these days you keep going back over something that went wrong, at home, in love or at work, and it feels easier to describe it as if you had only watched from the outside. Melphi asks you to take one step further: acknowledge the part you played, with no trial and no self-acquittal. This is not a guilt to pay off, it is a strength: whoever can say “I was there too” can tell the truth, and above all can start again from that point. Before you judge the people who let you down, calmly look at where you were standing.

The historical translations

Annibal Caro (1581)
Ch’io stesso il vidi, ed io gran parte fui
Del suo caso infelice. E chi sarebbe,
Theodore C. Williams (1910)
and bore great part in each event I tell.
