@Perikles & Pjt: I think Profesoradeespañol meant "el énfasis en el verbo".
"Elena viaja a Francia" is the usual word order of a sentence, with a natural stress on the subject. But using the verb at the beginning of the sentence puts an emphasis on
the action. Same kind of thing with "A Francia viaja Elena", which would emphasize
the place.
Certainly, neither "Viaja Elena" or "A Francia viaja" would be commonly heard sentences, but they are grammatically correct, and this kind of formulas can be found in literary texts, with a specific purpose.
