Samuel's beasties

In my previous career I had the pleasure to work for a school that was located at St Donat's, one of Britains' best medieval castles in Wales. They had an original Tudor-era "Beastie Garden"; a rose garden with a circle of heraldic beasts on high plinths. I was told that if you would stand in a place where any of the beasts would not be able to see each other, you would disappear and never be seen again. So you can imagine I am a little bit fascinated by this wonderful 1840s "griffin" vase by Samuel Alcock!
