Samuel Marinus Zwemer,
Arabia: The Cradle of Islam
“ In scenery and climate, Yemen fares worst of all the provinces. The two gateways to Arabia Felix are very infelix. What could be more dreary and dull and depressing than the “gloomy hills of darkness” that form the background to Aden as seen from the harbor? There is no verdure, no vegetation visible; everywhere there is the same appearance of a cinder heap. And where can one find a more filthy, hot, sweltering, odorous native town than Hodeidah? Yet these two places are the gateways to the most beautiful, fertile, populous and healthful region of all Arabia. ”
