the rider saber battle , actually went precisly like the bellerophon chimera fight

Bellerophon mounted his steed and flew off to where the Chimera was said to dwell. When he arrived, the Chimera was truly ferocious, and he could not harm the monster even while riding on Pegasus. He felt the heat of the breath(excalibur) the Chimera(saber) expelled, and was struck with an idea. He got a large block of lead and mounted it on his spear. He then flew head-on towards the Chimera, holding out the spear as far as he could. Before he broke off his attack, he managed to lodge the block of lead inside the Chimera's throat. The beast's fire-breath melted the lead, and blocked its air passage

except saber(chimera) won this fight ( no dont worry this isnt who saber really is )
also:
Pegasus was eventually turned into a constellation, but a single feather fell to the earth near the city of Tarsus

i think thats nice use of the myth, the "feather" being the shooting star like comet it turned into

edit: pegasus rules dammit!!, i wouldnt mind having that horse
