Is this the earliest brilliant move?

Believe it or not, I got a 'brilliant' move as white on move 3 in a recent game review. This was the Knight sacrifice in the Damiano Defense. I was very surprised because it was always my understanding that this was the standard book response to the Damiano 2 ... f6. Here's the first stage of the game (which soon ended with black's resignation, but you don't need to see that). Whoops! Just seen that Ashertheoof got exactly the same and posted above before me. Sorry! Agree with colecollector (above) that this is a standard book move, as I say above, but technically it is given by chess.com as 'brilliant' and it seems so far to be the earliest one achievable in any game which is what this thread is about. Kind of cheapens the two 'brilliants' given to my positional exchange sacrifice and knight sacrifice in another of my games, of which I was (up to now) rather proud!

This brilliant move was made on the 7th turn.
