res futuras praedicenti

[pmda]

Nemo Cassandrae res futuras praedicenti credebat.

Orberg habet responsum quod super est in LLPSI exercitia pars ii.

I imagined that the dative object that no one believed would be the entire 'res futuras praedicenti'...

so it should read:

Nemo Cassandrae rebus futuris praedicenti credebat....

Or is it dative Cassandrae that is not being believed...? But then how does the sentence work. What are 'res futuras' objectives of....?

[Craig_Thomas]

Cassandrae is dative after credebat, and res futuras is the object of praedicenti: they didn't believe Cassandra when she spoke of things to come.

[Junya]

Nemo Cassandrae res futuras praedicenti credebat.

How about this explanation ?

Nemo : the subject of the sentence
Cassandrae : dative case, which credere takes as its object
res futuras : accusative case, which praedicere takes as its object
praedicenti : dative case of the participle which modifies Cassandrae (Cassandra foretelling, Cassandra who is foretelling)
credebat : the main verb and predicate of the sentence, the subject is nemo, the object is the dative case of Cassandra
