Boundaries - Time's Arrow, Time's Cycle: Myth and Metaphor in the Discovery of Geological Time - page 186

In Burner's grand display of universal history, Christ stands atop a circle of globes,
proclaiming (in Greek) his immanence in the famous passage from Revelation: I am
Alpha and Omega. In Hampton's design, Christ's throne stands top and center, and
Hampton used the same quotation to illustrate his plan—for his blackboard (Figure 5.4),
with its sketch of his entire concept, proclaims at top center, I AM ALPHA AND
OMEAG [ sic ] THE BEGINNING AND THE END.
Figure 5.4
Hampton's blackboard, showing his plan for the entire composition. Note its near
identity with Burner's frontispiece: Christ stands at the top of each, proclaiming the
same line from Revelation. History is a circle beginning and ending at the central Christ.
