Arrian of Nicomedia

Greek: Ἀρριανός Arrianos, Latin: Lucius Flavius Arrianus,[4] was a Greek historian, public servant, military commander and philosopher of the Roman period.[3]
The Anabasis of Alexander by Arrian is considered the best source on the campaigns of Alexander the Great. 
For a period, some time about 126 AD, a friend of the emperor Hadrian, who appointed him to the Senate. First consul suffectus, during 132 AD (Howatsonshows 131) he was made prefect or legate (governor) of Cappadocia, by Hadrian, a service he continued for a six-year duration. When he retired, Arrian went to live in Athens, where he became archon sometime during 145 or 146 (EJ chinnock shows, he retired to Nicomedia and was appointed priest to Demeter and Persephone while there). He died in the reign of Emperor Marcus Aurelius.[13][16][20][21][21][22][23][24][25]
Arrian referred to himself as the second Xenophon, on account of the reputation and esteem of him. Lucian stated him to be:[17][26] a Roman of the first rank with a life-long attachment to learning
— — — quote of Lucian in P. E. Easterling, B. M. W. Knox, p.143
Τhis quality is identified as paideia (παιδεία) which is the quality considered to be of one who is known as an educated and learned personage, i.e., one who is highly esteemed and important.[17][27][28][29][30][31]
=== Techne Taktike[edit] ===
Written 136/137 AD (in the 20th year of Hadrian[34]), it is a treatise on Roman cavalry and military tactics, and includes information on the nature, arms and discipline of the phalanx. The hippika gymnasia is particularly a concern of Arrian in the writing.[25][57][58][59][60][61][62][63]
Another translation of the title is Ars tactica, in Greek is Τέχνη τακτική.[64][65]
This work has generally been considered to be in large part a panegyric to Hadrian, written for the occasion of his vicenallia, although some scholars have argued that its second half may have had practical use.[66][67]
=== Kynēgetikos[edit] ===
Cynegeticus (Κυνηγετικός), translated as the hunting man,[21] is a work about hunting dogs, canes venatici, the Celtic grey-hound.[68][22][69][70][71][72][73]
The work is based on an earlier exposition made by Xenophon, whom Arrian thought to be the authority on the subject of hunting.[74][75]
