4. "Here I stand at the milestone of my days"

From: http://en.wikipedia.org/wiki/Marlene_Dietrich

Dietrich's gravestone in Berlin. The inscription reads "Hier steh ich an den Marken meiner Tage" ("Here I stand at the milestone of my days&quot , a paraphrased line from the sonnet "Abschied vom Leben" ("Farewell from Life&quot by Theodor Körner.

After we have been asked over and over again
for the meaning of the inscription on Marleneís
tombstone (Hier steh ich an den Marken
meiner Tage) we finally asked Maria Riva what
the translation would be like: And here is her
answer:
Here I stand in the benchmark of my days."
(Literal)
"I remain as/in the proof of my days." (loose)
What Dietrich liked was what she interpreted as
its meaning:
1. I am what I am.
2. I remain the proof of me
