 | July 11th 1809-August 19th 1809 | Proposal for what the flag of Iceland might have looked like during the rule ofJørgen Jørgensen | It’s not fully known what Jørgen’s flag really looked like. There are no surviving copies and his original description simply read as: “The Icelandic flag shall be blue, with three whitestockfishes on it”.[1] Due to this vague description, there can be multiple different interpretations of what the flag looked like. The example shown here shows three stockfishes in the first quarter on a dark-blue field. The word “stockfishes” in Jørgen’s description could also be interpreted simply as “cods”, so the symbols on his flag might not have been stockfishes |
