"When I had lifted up my brows a little,
The Master I beheld of those who know,
Sit with his philosophic family.
All gaze upon him, and all do him honour.
There I beheld both Socrates and Plato,
Who nearer him before the others stand;
Democritus, who puts the world on chance,
Diogenes, Anaxagoras, and Thales,
Zeno, Empedocles, and Heraclitus;
Of qualities I saw the good collector,
Hight Dioscorides; and Orpheus saw I,
Tully and Livy, and moral Seneca,
Euclid, geometrician, and Ptolemy,
Galen, Hippocrates, and Avicenna,
Averroes, who the great Comment made."
~ Dante, Inferno: Canto IV
