The theme that unites the most distinctive sites of Artemis is the idea of dangerous or threatened passage. She was particularly associated with places of narrow access, both straits of water and mountain passes—the sensitive places necessary for a city’s defense but also the places most vulnerable to enemy penetration. Her inland sites tended to be located, as Pausanias indicates, along main roads, especially where these passed between high mountains. Artemis was imagined to dwell in the mountains, but her sanctuaries were not peak sanctuaries. It is not the mountains themselves that were sacred to her but the narrow passes in between. Mountains associated with Artemis were the mountains located at borders. Artemis as protector was the scout who watched for danger; hence she could be called Proskopa, ‘Lookout’.
