The ceiling is supported by a forest of 336 columns, each 9 metres (30 ft) high, arranged in 12 rows of 28 columns each spaced 5 metres (16 ft) apart. The of the columns are mainly and styles, with the exception of a few style with no engravings. One of the columns is engraved with raised pictures of a Hen's Eye, slanted braches, and tears. This column resembles the columns of the from the 4th century (AD 379–395), erected in the. Ancient texts suggest that the tears on the column pay tribute to the hundreds of slaves who died during the construction of the Basilica Cistern.

In Oak Ridge, einem Zentrum der Atomforschung in der USA, ereignete sich vor vielen Jahren eine stille Heldentat: Weil eine Kontrolllampe versagt hatte, wurde der sogen. Kritische Punkt überschritten und die Kettenreaktion ausgelöst, die sich auch bei der Explosion einer Atombombe abspielt – Neutronen treffen auf winzige Uran-Teilchen, die darauf zerfallen und viele andere Uran-Teilchen mit Neutronen bombardieren und so immer weiter, immer schneller, immer heißer. Hinter den Bleiwänden von Oak Ridge lief nun dieser unheimliche Prozess in beängstigendem Tempo ab, und die Katastrophe, die Tausenden das Leben kosten würde, schien nicht mehr aufhaltbar. Da ging ein junger Physiker in die „Todeskammer“ und tat dort rasch die notwendigsten Handgriffe, um die Kettenreaktion zum Stehen zu bringen. Von Milliarden unsichtbarer Strahlen durchbohrt verließ er still den unheimlichen Raum; wenig später starb er unter schrecklichen Schmerzen.
