This is a beautiful, delicate object from the age of the luxury steamship travel. The four panels represent Amphitrite with her trident, perhaps Doris, or Thetis, or other Nereids, riding the Dolphins. Four birds between the panels are depictions of Phoenix, reflecting upon the coat of arms of the Carron Company.
The quality of the casting is quite detailed, crisp, all intact. Gilding on the obverse is largely intact. Patina is beautiful. Object measures 19cm/7.5" in diameter.
This grille possibly functioned in a heat or ventilation duct, or had another function in a luxury cabin on one of the Carron Steamship Line passenger vessels, or in captain's quarters. Based on the subject matter, the decorative elements, I would date this to the late 19th-early 20th century.
This is a rare, possibly unique survivor from the days of luxury transoceanic liner travel!
