Answer: "Next door to each other, in the brick-walled city built by Semiramis"
Step-by-step explanation:
Pyramus and Thisbe is an opera by John Fredrick Lampe.
It is a Babylonian love story of a man (Pyramus) and a woman (Thisbe).
They were in love but their parents refused to consent to their union.
Their houses stood side by side and the only way they were able to communicate was through a crack in the wall separating their houses.
This line: "Next door to each other in the brick-walled city built by Semiramis" establishes the setting of the story
