The title means Mrs. Pavesi is Homesick
The piece is about the inmigration from Italy to USA.
Mrs Pavesi is a "symbolic" woman from the flat lands of Pavia
(the chanel on the fiused glass is the Naviglio Pavese that conect milano
with pavia from the times of Leonardo Da Vinci...)
I imagine that woman from Italy uing on that american washing board and
thinking about her home, far away...
