The Fleur de Lys Doorbell Ringer has been cast in solid bronze. It was hand crafted using the age-old art of foundry casting. During the process the molten metal was heated to over 2000°F then carefully poured into a handmade sand mold. This mold was used only once, giving this Doorbell Ringer its individual character. The Oiled Bronze Fleur de Lys Doorbell Ringer was designed by Michael Healy, an accomplished Rhode Island artisan known for his truly Unique Doorbell Ringers. Contrary to popular belief, the Fleur de Lys did not originate in France, but rather was first popularized in ancient Rome. Michael, an avid history buff, was inspired to create this Fleur de Lys Doorbell Ringer in the spirit of its original significance. The Fleur de Lys (derived from the Celtic word "li" or "lly" meaning king or ruler) is a symbol of power, life and purity and was first coined as the "flower of kings." What a uniquely elegant way to greet visitors. Compatible with all wired doorbells. Mounting hardware included.
