Similar forms are found in the hovering winged disc and sacred trees[22] of Mesopotamia, the caduceus wand of Hermes, the ubiquitous scrolled scallop shells in the canopy of the Renaissance sculptural niche, originating in Greek and Roman sarcophagi, echoed above theatrical proscenium arches[23] and on the doors, windows, wrought iron gates and balconies[24] of palaces and grand houses; the shell-like fanlight over the door in Georgian[25] and similar urban architecture, the gul[26] and[27] boteh motifs of Central Asian carpets and textiles, the trident of Neptune/Poseidon, both the trident and lingam of Shiva, the 'bai sema' lotus-petal-shaped boundary markers of the Thai inner-temple, Vishnu's mount, Garuda,[28] the vajra thunderbolt,[29] diamond mace or enlightenment jewel-in-the-lotus of Tibet and South-East Asia, the symmetrically scrolled cloud and bat[30] motifs and the similarly scrolled ruyi[31] or ju-i scepter and lingzhi[32] or fungus of longevity of the Chinese tradition. Both as a form of the lotus rising from the swamps to touch the sun and as a (palm) tree reaching from earth to heaven, the palmette carries the characteristics of the axis mundi or world tree. The fleur-de-lis, which became a potent and enigmatic emblem of the divine right of kings, said to have been bestowed on early French kings by an angel, evolved in Egypt and Mesopotamia as a variant of the palmette.
