I just loved this double clock face. It gave me several ideas for artworks, so I thought it would also be a good image to share will all of you. It’s from Olaus Magnus’ famous Historia de Gentibus Septentrionalibus (History of the Northern Peoples), which was printed in Rome in 1555. A combination of history and folklore about Sweden, it achieved the 16th c. equivalent of best seller status; It was translated from Latin into Italian, German and English, and was also issued in several ‘abridged’ versions.
