EDITORS COMMENTS
This print captures a remarkable commemorative medal that pays tribute to the groundbreaking work of two renowned astronomers, Pierre Janssen and Norman Lockyer. In 1868, these French and English scientists independently conducted spectroscopic studies on solar prominences and made an extraordinary discovery. They both observed a distinct yellow line in the solar spectrum, which Lockyer named Helium after the Greek word for sun, "helios". The reverse side of this fascinating medal showcases Phaeton driving his father Apollo's chariot near the sun, drawing inspiration from Greek mythology. The image beautifully portrays the significance of their findings by combining elements from ancient mythology with scientific breakthroughs. It symbolizes how human knowledge has evolved over time to unravel the mysteries of our universe. This piece serves as a testament to their contributions in advancing our understanding of astronomy during the 19th century. The inclusion of Phaeton driving Apollo's chariot emphasizes mankind's relentless pursuit to explore celestial realms and harness scientific progress for transportation purposes. The horse-drawn chariot represents not only ancient modes of transport but also signifies humanity's desire to conquer new frontiers. Overall, this print encapsulates an important moment in history when two brilliant minds revolutionized solar astronomy through their spectroscopic studies. It stands as a reminder that curiosity and dedication can lead us towards incredible discoveries about our world and beyond.
