“What will the stream become in its lengthened course, if it be so turbid at its source?”
Pietro Metastasio (1698–1782) Italian poet and librettist (born 3 January 1698, died 12 April 1782)
Qual diverrà quel fiume,
Nel lungo suo cammino,
Se al fonte ancor vicino
É torbido così?
Part I.
Morte d' Abele (1732)
