Assuming we're just looking at this phrase, "learn'd" suggests that the astronomer studied to become intelligent in the astronomical field.
" I have been all along expecting some one of imposing presence and superhuman strength, whereas he turns out to be a little insignificant weakling, who has managed to blind my eye by taking <span>advantage of me in my drink; come here, then, Ulysses"
Cyclop
was foretold that he will be harmed by Ulysses but the seer never told
how it will happened and Polyphemus was completly suprised</span>
<span>"The worst that could be said of him was that he did not represent his class.</span>
A similarity they both share is the fact that the death of multiple man is heavily present in both stories however their locations and background are completely different.
Hope this helps :)
