From his closest friend, Horatio, Hamlet learns of an extraordinary visitation that took place the night before. Horatio witnessed the marching by of a fearsome apparition-- surly no flesh-and-body creature-- but rather some sprit or ghost in the very image of the late king arrayed in battle armor.

Although I have looked up all the vocabulary in dictionaries, in fact, I am wondering what some of them could mean-- the bold parts.
