A study against the weather record
Caspar David Friedrich
Meadows near Greifswald
An earlier drawing of Greifswald became a later studio painting. What does that gap let the weather record test?

How this study was read
The method in fullWhat is written
The museum dates the painting 1821/22. Its drawing is probably from around 1806 and was reused in Dresden. The 1806 journey is documented; the day of the meadow drawing and the weather represented in the canvas are not.

Records of those days
- The museums’ 1806 chronologyDeparture from Dresden on 24 April; Greifswald on 13 June; Rügen from 29 June to 20 July; return in August. May–July supplies three whole calendar months of travel context, not dates for the drawing.
- Berlin Climate Record, Kadow et al. (2016)Daily mean temperatures for Berlin’s changing inner-city observing sites. Regional context for the journey only; temperature supplies no test of cloud or haze at Greifswald.
Not found or not yet searched
- No inscription or contemporary document has been verified that dates this drawing to a day or month.
- No local weather testimony has been verified for its making. Greifswald’s DWD daily archive starts much later.
Each claim tested
- Does the canvas date identify the weather to compare? No. The museum connects the later studio canvas to an earlier drawing, also used for a moonlit view. The making history separates a recorded place from a recorded sky.
- What did Friedrich change? The museum’s account describes a strongly symmetrical arrangement of the view. Birte Frenssen, discussing the drawing in Weltkunst, identifies an elongated, narrowed church tower. These are attributed readings of his construction of the landscape.
- Can the regional thermometer confirm the painted cloudless sky? No. Berlin’s temperatures describe Berlin during the journey. They neither verify nor contradict cloudlessness or haze at the meadow.
Verdict
A recognisable Greifswald view was reshaped for a later studio painting. The documentary dates support travel context, but do not turn the painted sky into an observation from a known day.
- UnknownThe weather in the painted sky The drawing has only an approximate year and the canvas was made later; no local sky record can be matched.
What this cannot tell you. The museum uses 1821/22; Heck’s 2018 article uses the broader 1820–22. Neither gives a weather day. The Berlin series changes observing sites. Its publisher corrected identified errors but applied no additional bias correction. No modern anomaly or weather rank is claimed. The 1806 weather window concerns the journey and is conditional context for a drawing only probably dated to that year.
Step 1 · How the picture was made
The drawing precedes the sky in paint
The Hamburger Kunsthalle dates this canvas 1821/22. The Pommersches Landesmuseum, which holds the preparatory meadow drawing, says Friedrich used it in his Dresden studio for both Greifswald in Moonlight (1817) and this later painting. A view recorded on paper could therefore serve more than one painted illumination.
The drawing’s date needs a qualifier. Johannes Grave’s museum account places it probably around 1806; this study has not established a dated inscription on the sheet. The canvas date also varies: the museum uses 1821/22, while Kilian Heck’s 2018 article uses the broader 1820–22. Neither date identifies the weather represented.
The museums’ chronology records departure from Dresden on 24 April 1806, a stay in Neubrandenburg in May, Greifswald on 13 June, Rügen from 29 June to 20 July, and return to Dresden in August. We use May–July 1806, the three whole calendar months between departure and return, for regional travel context. This is not a claim that the meadow drawing was made within those months, or that Friedrich stayed continuously in Greifswald.
The date evidence is a modern museum chronology and the museums’ accounts of the drawing. No artist’s letter or contemporary weather diary has been verified that fixes the making of this sheet.
Step 2 · What Friedrich changed
A recognisable city, deliberately arranged
Grave describes the city centred in a strongly symmetrical composition, set between green meadows and a luminous, cloudless sky. Haze distances the town. Heck likewise reads the contrast between the remote city and the near horses and meadows as part of the picture’s effect. These are descriptions of the painting, not measurements of atmospheric visibility.
The construction begins on paper. In Simon Elson’s report on the drawing, curator Birte Frenssen identifies the alteration of St Nicholas’s tower: Friedrich narrows and lengthens its rounded baroque upper part. The city remains identifiable, but topographical recognition does not mean that every feature has been copied unchanged. Nor does the reuse of the drawing establish that either painted sky records the weather when he drew it.

Step 3 · The regional record
Berlin during the 1806 journey
The Berlin Climate Record provides all 92 daily means for May–July 1806. Its reference point is about 177 km south of Greifswald. That distance is calculated to the city reference point, not to an exact drawing viewpoint. These are Berlin temperatures, shown to put the journey in a regional setting; they are not local observations at the meadow.
June’s mean in this series is lower than May’s, followed by a warmer July. The daily values show the variation within those months. Neither result tests the painting’s cloudlessness: temperature alone does not tell us the cloud cover, and no day of the drawing has been established.

The series combines changing inner-city observing sites and ends in 1934. We publish no weather rank or comparison with a modern normal. The monthly means are summaries of this historical series, not estimates of Greifswald’s temperature.
Step 4 · What the comparison can establish
The place is traceable; the weather day is not
The evidence supports a study of how Friedrich made the picture: an earlier view of his home city, altered in the drawing and reused in a later studio composition. It does not support dating the canvas’s sky from a thermometer. The painted weather remains unknown; the Berlin record neither verifies nor contradicts it.
The DWD daily inventory checked here starts Greifswald station 01757 on 1 March 1898, too late for the drawing or canvas. Lund’s downloaded monthly archive has no entries for May–July 1806. These are specific archive gaps, not proof that nobody observed weather locally. A securely dated drawing and a matching local account of cloud or visibility would be needed to make a closer test.
