Kalonymus ben Kalonymus

Kalonymus ben Kalonymus ben Meir (Hebrew: קלונימוס בן קלונימוס), also romanized as Qalonymos ben Qalonymos or Calonym ben Calonym, also known as Maestro Calo (Arles, 1286 – died after 1328), was a Jewish philosopher, translator, and hakham of Provence.

Kalonymus studied philosophy and rabbinical literature at Salon-de-Provence under the direction of Abba Mari ben Eligdor and Moses ben Solomon of Beaucaire. Kalonymus also studied medicine, but seems not to have practiced it.

Kalonymus was from a prominent and distinguished Provençal Jewish family. Kalonymus and Kalonymus's father each bore the title Nasi (prince).
