Dante Alighieri

Heat cannot be separated from fire, or beauty from the eternal.

The customs and fashions of men change like leaves on the bough, some of which go and others come.

A fair request should be followed by the deed in silence.

The experience of this sweet life. L'esperienza de questa dolce vita.

A great flame follows a little spark.

The purpose of the whole (work) is to remove those who are living in this life from a state of wretchedness and lead them to the state of blessedness.

I was so full of sleep at the time that I left the true way.

Nature is the art of God.

For where the instrument of intelligence is added to brute power and evil will, mankind is powerless in its own defense.
