Whichever way man could turn, he still saw Him.
And at the same time he saw his own soul as in a mirror that reflected it; in certain animals, certain colours, and certain plants he could discern the qualities which it was his duty to acquire, the vices against which he had to defend himself.
And he had other examples before his eyes, for the symbolists did not restrict themselves to turning botany, mineralogy, natural history, and other sciences to the uses of a catechism; some of them, and among others Saint Melito, ended by applying the process to the interpretation of every object that came in their way.

A cithara was to them the breast of the devout man; the members of the human frame became emblematical: the head was Christ, the hairs were the saints, the nose meant discretion, the nostrils the spirit of faith, the eye contemplation, the mouth symbolized temptation, the saliva was the sweetness of the inner life, the ears figured obedience, the arms the love of Jesus, the hands stood for good works, the knees for the sacrament of penance, the legs for the Apostles, the shoulders for the yoke of Christ, the breast for evangelical doctrine, the belly for avarice, the bowels for the mysterious precepts of the Lord, the body and loins for suggestions of lust, the bones typified hardness of heart, and the marrow compunction, the sinews were evil members of Anti-Christ.

And these writers extended this method of interpretation to the commonest objects of daily use, even to tools and vessels within reach of all.
Thus there was an uninterrupted course of pious teaching.

Yves de Chartres tells us that priests instructed the people in symbolism, and from the researches of Dom Pitra we know that in the Middle Ages Saint Melito's treatise was popular and known to all.

Thus the peasant learnt that his plough was an image of the Cross, that the furrows it made were like the hearts of saints freshly tilled; he knew that sheaves were the fruit of repentance, flour the multitude of the faithful, the granary the Kingdom of Heaven; and it was the same with many pursuits.
