O sibile, se ergo! Fortibus es in ero.
Nobile! Demis trux!
Vatis inem.
Causan dux.

This appears to me to be a song praising the virtues of a young maiden. Here's my stab at it:

Oh Sybil, you go girl!
Your strength is like a noble fir.
Humble child,
Semi-wild,
Prophet, poet,
Leader, Guide.

How did I do, Magister Tsuwm?
