Edirne - Üç Şerefeli

Plan combining different types of stars

The Üç_Şerefeli mosque in Edirne dates from the 5th century. The same construction of this muqarnas is used in otherTurkish mosques too:
  • Üç Şerefeli mosque in Edirne (1447)
  • Fatih mosque in Istanbul (1462)
  • Hatuniye mosque in Tokat (1484)
  • Beyazit mosque in Edirne (1487)
  • Yavuz Selim mosque in Istanbul (1528)
In next applet you can follow stepwise how the plan is drawn using a compass construction:
  • In the rectangular plan a half circle is drawn around the apex.
  • Additionally on the left and on the right large circles are drawb circumscribing a 9-pointed star.
  • Around this 9-pointed star a circle of 5-pointed stars is created.
  • Beneath in the middle a half 10-pointed star appears and in the upper corners we can see quarters of 10-pointed star.
  • The remaining place is filled in with additional irregular figures.
Beneath the applet you can see how Shiro Takahashi accentuates the different types of stars using different colors.

On the picture you can recognise the different elements of the plan:
  • Below you recognise the supporting base shaped as a half 10-pointed star
  • Left and right you see the big 9-pointed stars as domes with a big stalactite in the center
  • The circles of 5-pointed stars around the big stars appear as circles of stalactites.
  • The half 10-pointed star in the apex appears as a niche in the apex of the muqarnas.
