Thanks Mapper for the comment
My idea, for a long time, was to translate these articles to english(is not dificult with google translator and my little acknowledgment of the English, to upload here for the article section of the Tomes of Wisdom, but it seems that the section is still delayed for long time.
When this section will be activated again I will try to translate them for it.
Keep looking at the Spanish page because this is only the first article about conversions, painting and constructions (buildings and Minas Tirith walls) that I’m writing in the next months
