"their bed"
Language
Act 2,
Scene 1
Lines 60-73
Oberon
Titania
Oberon
Titania
This is an example of a literary device called metonymy. Instead of naming what you’re talking about, you name an object closely related to it. When Titania says that Oberon has come to bring joy to Theseus and Hippolyta’s bed, she obviously means that he has come to bring joy to their marriage — not to a piece of furniture.
