Others editions have “tristful” visage instead of “heated.”
I’m guessing one is a Q1 or Q2 and the other is the folio? Heated does rather follow the glowing face a bit better, I suppose. It starts with just a little bit of heat – a little glow – to become heated. Tristful is a fun construction – a fun word. A little Italian, a little English – all sad.
But heated implies anger, tristful implies sadness – in both cases, heaven’s face is upset about Gertrude – as upset as the end of the world apparently.
Which, come on, Hamlet – is a little bit melodramatic. If I were Gertrude, I’d be like, “Come on, Hamlet. Whatever it is, I’m pretty sure it’s not the end of the world bad.”
