      "explanation": "Finberg places the two pencil drawings in a sequence of artistic choices and connects the second with the oil exhibited in 1811. His account offers a composition to investigate. It does not document Turner’s actual decision in Turner’s own words.",

      "without": "The museum’s attribution remains visible. With it set aside, the light can still be described, but this reading no longer explains it through Cuyp.",
      "next": "An exact passage from Turner’s lecture, read alongside a named Cuyp painting, would make the proposed influence more specific. It would still need an argument connecting it to this work."

      "explanation": "The sketches raise questions about arrangement; the museum’s account raises questions about a tradition of light. Together they offer two ways into the making of this atmosphere. They do not establish a single cause, exclude direct observation, or recover weather on a particular day. This is a synthesis of existing scholarship, not a new attribution.",
      "without": "The combined account needs both connections. The remaining source can still support its own, narrower reading; it cannot stand in for the connection you set aside.",
      "next": "The strongest next addition is an object-specific link: a verified sketch identification, a relevant statement by Turner, or technical evidence about revisions to this painting. Another weather series would not by itself establish those links."
