Romeo and Juliet is the nickname, in the Invisible Cities chronicle, of the true Sforza heir of Milan and his Aragonese wife, a daughter of the king of Naples. They were meant to rule Milan and did not: in the interregnum they died “strangely,” two young people dead in an embrace, which left the way clear for the Moor. The name they are remembered by is not their own.
At the castle they are seen: on moonlit nights a couple closely resembling them walks the gardens.
The figure returns outside Milan. When Sisi takes an open flank and drives her thin-bladed sword under Adepto’s armpit, piercing his heart, that death is said to resemble the scene of Romeo and Juliet.
