Hip rafters twisted into the roof surface

Robert Simpson sent me an email with a picture of a drawing of a lectern in Sevilla, Spain. Just about every medieval cathedral has an Octagonal baptismal  and the base of the lectern is Octagonal with the legs of the lectern rotated into the roof surface. Or as Robert stated... twisted into the roof surface. This lectern  looks like some of the bases holding up the masterpieces of the European Trade Guilds dating back to the 13th century.

Possible base of an masterpiece with Saint Andrew's Cross.

Sim,

Earlier this month we were in Sevilla, Spain. In the massive cathedral there was a lectern under repair. Its name in Spanish is Facistol del Coro.You could not see it as it was protected by boards, but on the boards was some explanation, including this illustration.You can see in photo Rafters 1 that the lectern consists of a heavy base, a wooden support structure and a decorative cover with a cupola. Photo Rafters 2 show the support structure a bit bigger, and what do we see?  Hip rafters twisted into the "roof" surface . . .

Recently the construction St Andrew's Cross has come up a lot in your blog.

In the third photo I thought you might like to see its gruesome origins (by Juan de las Roelas, in Fine Art Museum, Seville). de las Roelas, like many artists of 16th century religious work in Spain, was born in Flanders, the area of Belgium where I live.
