Four models unexpectedly added the Sagrada Família’s magic square to their AA-3D scenes, offline and unprompted: Claude Fable 5.1 and Sonnet 5.5 featured it visibly, whereas Grok 4.7 and Step 5 Preview hid it behind a pillar
The sculptor Josep Maria Subirachs carved the square into the Passion façade. Its total, 33, is the traditional age of Jesus at his death.
Subirachs based the square on the one in Albrecht Dürer's 1514 engraving Melencolia I, which adds up to 34. He lowered four of its cells by 1, so 14 and 10 each appear twice.
