Picture is part of the presentation 'Module of the Oppler's synagogue in Wroclaw'. It shows combining drawings to obtain the lastest version of the project. Picture combines longitudinal section of the executive project with drum elevation. Even though the longitudinal section is the most up-to-date drawing of the whole building, the drum part on the drawing is different in comparison to what was actually built (as seen at photos). The elevation drawing was probably a replacement project for this part of the building made after the decision of diminution the height of the dome due to structural reasons.
