The Epistles of Apollonius of Tyana by Apollonius tr. F.C Conybeare [1912]

Think globally, act locally; Apollonius of Tyana was called, even in his day, a 'citizen of the world.' Befitting this, he seemed to have voluminous correspondence over a wide region. These are among the few actual writings attributed directly to him; a grab-bag of correspondence with other thinkers, his relatives, friends, merchants, kings, cities who wanted him to visit, and so on. He is friendly, concise, and frank; this is punctuated by invective which seems discontinuous. It is unknown how many of these epistles are genuine.
