Premise: Eurylochus and his followers now passed under a lofty portal , and looked through the open doorway into the interior of the palace .<br>The first thing that they saw was a spacious hall , and a fountain in the middle of it , gushing up towards the ceiling out of a marble basin , and falling back into it with a continual plash .
