 The beginning of the late stage is marked by the use of simple 16 @-@ point patterns at the Hasan <unk> mausoleum in Cairo in 1321 , and in the Alhambra in Spain in 1338 – 1390 . These patterns are rarely found outside these two regions . More elaborate combined 16 @-@ point geometrical patterns are found in the Sultan Hasan complex in Cairo in 1363 , but rarely elsewhere . Finally , 14 @-@ point patterns appear in the Jama Masjid at Fatehpur Sikri in India in 1571 – 1596 , but in few other places .
