I've revised the translation from the Spanish by going back to this earlier edit.  Subsequent edits on the Spanish-language Wikipedia seem to have been intended mainly to insert links, but have primarily succeeded in deleting chunks of the original text, rendering the result both ungrammatical and somewhat insensible.  I've taken 's translation and incorporated the previously omitted text, and gone over the whole to make it more idiomatic in English.  It's not quite there, yet, but is hopefully now serviceable.  ( )
