Lord of Light's symbol is a firey what?

[Merkuri]

I've been listening to the Song of Ice and Fire series on an audio book. I'm nearing the end of the third one and something has been bothering me for a while. I can't tell whether the symbol of the Lord of Light is a firey heart or firey hart. A quick Google search didn't turn up anything useful. Can anyone who actually read (as opposed to listened to) the books tell me which it is, or if it's something altogether different?

No spoilers, please. I'm enjoying these books immensely and don't want them ruined.

It's a fiery heart. There's some illustrations of it in my version of the paperback.

Muchas gracias!

That was the first thing I thought of when I first encountered the symbol, but the more I got into the books the more I started doubting it. The author likes to use a lot of more archaic terms for things, so "hart" meaning a stag wouldn't be out of the question, and I had the feeling that the heart symbol that we associate with valentines day and love was probably not used much in the middle ages. Not sure where I got the idea, but I feel like the heart is a more modern symbol.

But now I don't have to wonder anymore. Thanks again!
