I have come across this curious article (it is in Italian, so you will need to use an automated translation to read it). In case you had multiple piercing and thought you were modern... In fact, you are very much old-fashioned! :) The lady in the picture is Infanta Maria of Guimarães (12 August 1538 – 7 September 1577) was a Portuguese princess.
She was not the only one who had multiple ear piercing! Follow the link above to the original article and you will find more portraits of the ladies who lived at the same time.
Interesting how it works... You know how people see some star wearing something and everybody wants it? That never worked for me. However, knowing that that was a style of a medieval princess... makes me regret that I do not have multiple piercing like this! :)
