NUDEC polyester sheets, made with raw material of SK Chemicals (Korea), are converted into the light of the transept aisle
When we enter into the Expiatory church through the Passion façade, via the transverse nave that links to the Nativity façade, just halfway above, the magnificence of the building can be admired. There, in the middle and at the centre of the intersection, the visitor will be able to look up at any of the prodigious details of ethereal light and laborious colours, surrounded by the four evangelists, represented by four tetramorphs according to the project by Domènec Fita.
Four 24 metres high trunk-like columns made of porphyry, a compact, hard rock, the most resistant material of those currently used in construction, rise vertically and cluster out at the top, to support the load of the central dome of The Christ (measuring some 170 metres) and the four columns of the evangelists that surround it, as last touch of Gaudi imagination.
In the same way the column starts off as arrises to end up as a circle, using the double twist technique. The NUDEC polyester panels are thermo-formed into translucent lighting fixtures that crown the ellipsoidal capitals. A flat, rigid, transparent shape, converted into a ductile, artistic object which gives forth a soft, coloured light, silhouetted by a copper figure, in yet another fine example of artists inspired by an artist.
