How does one pronounce "Gradiva," the character discussed by Jensen
and subsequently Freud? Is it a long i, or a long e?

As the comment below indicates, Gradiva is an Italian name, so the
pronunciation should be something like "grah-DEE-vah."   (More to the
point, that would be a long E sound.)

The G is pronounced more or less as in English. The R is pronounced
kind of like in Spanish, with a flip of the tongue against the gums of
the upper teeth. The D is a bit softer (less explosive) than in
English.  And as in most Italian words, the stress is on the
penultimate syllable.

Is this worth the cash really?

Long e. Grah-dee-vah.

It's an Italian name/word and the "diva" part is always pronounced
that way to my knowledge. My Italian grandmother backs me up on this
one.
