To what extent should the translation respect the grammar?

[Ruby Novacna]

I'd say that at least the "them" is ungrammatical

This would be called a "marked" word order

I just wanted to show you that a correct translation, in its first stage, can seem difficult to understand.
This is a sentence from Herodotus, which I found in the dictionary, which I had consulted following Stephen Carlson's comment.
The commentary said that if our text was ancient Greek, it should have a particular syntax. I was hoping, therefore, that among the forum members someone would recognise the personal pronoun in the second place of the sentence :
kaí spheas hōs oudeìs ekálee ektrépontai ep’ Athēnéōn
I had removed the word Athens so as not to point directly to ancient Greek.
The 1st step of the translation, word by word, gives :
and them as no one called they turn to Athens
The final translation, with the syntax of modern English
‘And since no one invited them, they turned toward Athens’ (Hdt. 6.34.2)

In conclusion, I believe that not only the "translators" but also the "commentators" of a translation must constantly improve their knowledge.
