In what way is the theme in this excerpt from "the lady of shalott" by alfred, lord tennyson similar to the theme of the poem "ulysses"?

down she came and found a boat
beneath a willow left afloat,
and round about the prow she wrote
the lady of shalott.

and down the river's dim expanse
like some bold seër in a trance,
seeing all his own mischance--
with a glassy countenance
did she look to camelot.
and at the closing of the day
she loosed the chain, and down she lay;
the broad stream bore her far away,
the lady of shalott.
