Bought this at the Mercer museum in the 90s, thinking I would one day retile our kitchen backsplash and add this in….hasn’t happened. In excellent shape - would like to spend more time out of a box! The Latin inscription from my take is Fluminus Impetus Laetificat Civitatem Dei, which Google says means “The River’s flow gladdens God,” or “the River maketh the city of God.” Thanks for reading and purchase benefits wildlife rescue.
