Alexander is built from Greek roots meaning "to defend" and "man," commonly translated as "defender of men." The name has carried that protective sense through millennia of use, from ancient conquerors to modern namesakes, and it tends to suggest someone who shields others rather than merely leads them.
Men may be said almost to be compelled by the Stars, even in voluntary actions, by means of their corrupt affections and ignorance. - Cardan Girolamo (1501-1576)
