Saint Michael's line
Saint Michael's line or the Sword of Saint Michael, also known as the Sacred Line of Saint Michael or the St Michael-Apollo Axis, is a straight line (a loxodrome or connected series of rhumb-lines) formed by transecting monasteries and churches in Europe and the Holy Land, eight of which are dedicated to the Archangel Michael. Several other notable sites on the same line in Greece are associated with ancient temples to Apollo.
