lived in Arles until May 1889, fifteen months

Is it possible to say "live fifteen moths" without "for" before a term? I think you can either use "for" or not.

ex)Van Gogh lived in Arles until May 1889, fifteen months during which he produced approximately two hundred paintings, a hundred drawings...

It's possible, but not in the way you ask here.
If you need to use "for", my opinion is that the following is is more natural:

Van Gogh lived in Arles until May 1889. For fifteen months he produced approximately two hundred paintings, a hundred drawings...

or
Van Gogh lived in Arles until May 1889. For the previous fifteen months he produced approximately two hundred paintings, a hundred drawings...

You culd say: Van Gogh lived in Arles from March 1888 until May 1889, fifteen months during which he produced approximately two hundred paintings, a hundred drawings...
