IX. (1.47) In reference to which fact, also, it appears to me to be that his grandfather also, by name Abraham, so called from his knowledge, would not endure to remain any great length of time in Charran, for it is said in the scriptures that "Abraham was seventy-five years old when he departed from Charran;"[Ge 12:4.] although his father Terah, which name being interpreted means, "the investigation of a smell," lived there till the day of is Death.[Ge 17:32.] (1.48) Therefore it is expressly stated in the sacred scriptures that "Terah died in Charran," for he was only a reconnoitrer of virtue, not a citizen. And he availed himself of smells, and not of the enjoyments of food, as he was not able as yet to fill himself with wisdom, nor indeed even to get a taste of it, but only to smell it; (1.49) for as it is said that those dogs which are calculated for hunting can by exerting their faculty of smell, find out the lurking places of their game at a great distance, being by nature rendered wonderfully acute as to the outward sense of smell; so in the same manner the lover of instruction tracks out the sweet breeze which is given forth by justice, and by any other virtue, and is eager to watch those qualities from which this most admirable source of delight proceeds, and while he is unable to do so he moves his head all round in a circle, smelling out nothing else, but seeking only for that most sacred scent of excellence and food, for he does not deny that he is eager for knowledge and wisdom. (1.50) Blessed therefore are they to whom it has happened to enjoy the delights of wisdom, and to feast upon its speculations and doctrines, and even of the being cheered by them still to thirst for more, feeling an insatiable and increasing desire for knowledge. (1.51) And those will obtain the second place who are not allured indeed to enjoy the sacred table, but who nevertheless refresh their souls with its odours; for they will be excited by the fragrances of virtue like those languid invalids who, because they are not as yet able to take solid food, nevertheless feed on the smell of such viands as the sons of the physicians prepare as a sort of remedy for their impotency.
