white marble mosaic panels of the Great Hall and Rotunda representing the Procession of Life. Working with Alexander, Meière drew her inspiration from the Siena Cathedral after the two toured the cathedral in the summer of 1925. Meière also drew inspiration from Siena for her ceiling designs of the Vestibule, Great Hall, and Rotunda representing Nature, Man, and Society. In addition to her thematic consultation with Alexander, Meière collaborated closely with the Rafael Guastavino Company of New York to create decorative timbrel vaulting. The vaults are composed of two types of ceramic tiles: glazed polychrome tile and unglazed acoustical terracotta tile called Rumford. Vestibule The Vestibule introduces the interior ornamentation of the capitol and represents Gifts of Nature. The sun is the room's central motif and is prominently featured as a medallion within the dome. The dome also incorporates mosaic images of agriculture, flora, and fauna. The vaulting is supported by the largest columns in the capitol—four monoliths of Red Verona marble. The columns' capitals, designed by Lee Lawrie, are vaguely Corinthian and feature bull motifs inspired from ancient Persepolis architecture. Great Hall The Great Hall follows the Vestibule and represents Life of Man. Three medallions—Traditions of the Past, Life of the Present, and Ideals of the Future—anchor the mosaic vaulting. Additionally, sixteen mosaic panels within the arches depict scenes of human activity, including an Architect, a Ball Player, and a Scientist. The Procession of Life begins in the Great Hall's floor with the mosaic Genius of Creative Energy—an Apollo-like figure—surrounded by Cosmic Energy, lightning, moons, orbs, etc. Three tondi (circular) mosaics follow, depicting the Spirit of the Soil, the Spirit of Vegetation, and the Spirit of Animal Life. The Great Hall also introduces the Nebraska Hall of Fame—a collection of bronze busts of noteworthy Nebraskans. The capitol's Thematic Consultant, Hartley Burr Alexander, is among the 26 current inductees. Rotunda The Rotunda follows the Great Hall and represents Virtues of the State. Eight winged virtues form a celestial rose within the mosaic dome: Temperance, Wisdom, Faith, Justice, Magnanimity, Charity, Hope, and Courage. The Procession of Life continues in the Rotunda's floor with the mosaic panel Vital Energy, which shows the Genius of Life—an Eros-like figure with butterflies and pine cones. At the Rotunda's center, four tondi mosaics representing the Genius of Water, the Genius of Fire, the Genius of Air, and the Genius of Earth surround a larger tondo mosaic
