Definition of Allusion
In Chapter 21, Griffin tries to make his way through London with his new condition. One of the obstacles that he has to traverse is a crowd surrounding a band. The song that the band plays is the hymn "When shall we see His face?" Although the lyrics are not mentioned in the text, the hymn is well known and thus functions as an allusion. The song is about being able to see the face of God after death. Here is a sampling of the lyrics:
We shall meet to part no more, some bright golden morning,
At the gates of glory where our loved ones stand;
Songs of vict'ry fill the skies in that hour of greeting,
Endless days, endless praise, when we see His face.
In Chapter 24, Griffin reveals his goal to Mr. Kemp. He wants to impose a Reign of Terror:
Unlock with LitCharts A+Not wanton killing, but a judicious slaying. The point is, they know there is an Invisible Man—as well as we know there is an Invisible Man. And that Invisible Man, Kemp, must now establish a Reign of Terror. Yes; no doubt it’s startling. But I mean it. A Reign of Terror. He must take some town like your Burdock and terrify and dominate it. He must issue his orders. He can do that in a thousand ways—scraps of paper thrust under doors would suffice. And all who disobey his orders he must kill, and kill all who would defend them.
