Architecturally speaking, Gordon is not a Gargoyle, but a Grotesque.
The difference being, Gargoyles would have had a water spout for dispersing rain water - their main function.
Grotesques on church buildings were intended to keep evil outside the church, and possibly to remind people what hell was like if they didn't go in!
But, in common with many others, we call all our Grotesques, Gargoyles :)
