This colourful gable stone on the wall of one of the buildings in the narrow St Jansstraat in Deventer (the alley I showed you yesterday) pictures a lady looking out of a window, and it refers to the presence of prostitution at this location in the past (presumably). I mentioned yesterday that Deventer is one of the oldest cities in our country, however this gable stone is rather 'new' as it was made by sculptor Ton Mooy (1948).
The poetic lines are by J.C. van Schagen (1891-1985), a Dutch poet who died in Deventer. The lines "eens halve kous heet nu St. Jan / maar wat er bleef dat af en an... / wat ik u brom u keert weerom" are really difficult to translate as the first two are hard to understand for me even in Dutch. The bottom line however ("let me tell you, you will return") apparently refers to the fact that the St Jansstraat is a dead-end street.
