Brazil Revisited

Yesterday's post Treasure Hunt, on a Brazilian weblog,
suggests a review of Brazil  in this journal.  The post
most relevant to yesterday's remarks is from
August 15, 2003, with a link, now broken, to the work
of Brazilian artist Nicole Sigaud* that also uses the
four half-square tiles used in 1704 by Sebastien Truchet 
and somewhat later by myself in Diamond Theory 
(see a 1977 version).

A more recent link that works:

* Sigaud shares the interests of her fellow Brazilian
   whose weblog was the subject of yesterday's
   Treasure Hunt.—

   "For many years I have dedicated myself to the study
    of medieval magic, demonology, Kabbalah, Astrology,
    Alchemy, Tarot and divination in general."

     — Nicole Sigaud (translated by Google) in a self-profile:

    I do not share the interest of these authors in such matters,
    except as they are reflected in the works of authors like
    Charles Williams and Umberto Eco.
