Henry Aristippus of Calabria (born in Santa Severina in 1105–10; died in Palermo in 1162), sometimes known as Enericus or Henricus Aristippus, was a religious scholar and the archdeacon of Catania (from c. 1155) and later chief familiaris of the triumvirate of familiares who replaced the admiral Maio of Bari as chief functionaries of the Kingdom of Sicily in 1161.
Aristippus was an envoy to Constantinople (1158-1160) when he received from the emperor Manuel I Comnenus a Greek copy of Ptolemy's Almagest.
[1] A student of the Schola Medica Salernitana tracked down Aristippus and his copy on Mount Etna (observing an eruption) and proceeded to give a Latin translation.
Aristippus himself produced the first Latin translation of Plato's Phaedo (1160) and Meno and the fourth book of Aristotle's Meteorologica.
Sylvester of Marsico died at the same time and Matthew of Ajello and the caïd Peter replaced him and Aristippus in the "triumvirate."
