Lorick #82:

to mortals, an immortal giver

he burned with great light to deliver

a traitor yes -twice

but pity his vice

his punishment hard on his liver

But first, we solve #83 - here it is one last time:

I'm a symbol, a body, a twin

a disease with a retrograde spin

a light in the morning

or else in the ev'ning

unfairly, I'm oft tied to sin!
