The Prince of India; Or, Why Constantinople Fell…
“ The Greeks on their side bore up bravely. Old John Grant plied the assailants with his inextinguishable fire. Constantine, in seeming always cheerful, never shirking, visited the walls; at night, he seconded Justiniani in hastening needful repairs.

Then the Emperor divided his time between the defences and Sancta Sophia—between duty as a military commander, and prayer as a Christian trustful in God. ”
