Geoffrey Chaucer was the first author known to link romantic love and St. Valentine's Day - and that was in poetry celebrating birds that mated for life, back around 1380. Hmmmm... Did earlier people realize how frail and false the human flesh was? We cannot trace romantic love and St. Valentine's Day back to the Age of Chivalry; that Code of Conduct was established between 1170 and 1220.
So why do we celebrate "romantic love," as human beings? For dreams and seemingly wonderful fairy tales?
In any event, I wish all of my readers a very happy Valentine's Day !
