There is no record by Goethe himself of the nature of the phenomenon perceived by him during that night, except for a brief remark in a letter to Mme de Stein, written the following day, in which he claims to have seen a 'northern light in the south-east' the extraordinary character of which made him fear that an earthquake had taken place somewhere. The valet's report makes us inclined to think that there had been no outwardly perceptible phenomenon at all, but that what Goethe believed he was seeing with his bodily eyes was the projection of a purely supersensible, but not for that reason any less objective, experience.
