Is this OK

Hoc responsum meum ad Q. viii in LLPSI Exercitia Latina:

  1. Quid prohibuit ne Troiani in Creta considerent.

In somno Aeneae Di Penates ad stare ei visi sunt et monuerunt ut eum et socii sui e Creta egrederentur.

While I can’t speak much to the content of your answer and its correctness (thought it does seem to provide a good reason why Aeneas and his guys didn’t settle on Sicily), I think I can help out a little bit with the grammar.

In somno Aeneae Di Penates ad stare ei visi sunt et monuerunt ut eum et socii sui e Creta egrederentur.

Since the subject of the main clause is di penates, anything that is reflexive would properly be referring back to them. So, in the ut-clause you have eum et socii sui in an attempt to refer to “Aeneas and his buddies.” I think eum et socii eius is what you are looking for.

I know that there are some reasons why a reflexive can be used to refer to the subject of a subordinate clause, but I don’t have time to look up a reference at this moment. In any case, di penates are still the subject of your ut-clause.

Also, it looks like you might have a bit of a typo: I think for ad stare you meant adstare.

Many thanks. That eius vs. suus thing was exlplained to me before. I’ll have to check it out again.

Nonnè rectiùs scribitur hoc, “eum monuerunt ut”, pro hoc, “monuerunt ut eum”?

vero ita dicis
