The profits arising from this land, with which he took no doubt much trouble and pains, he invested again in other ways.

He lent money to Greek cities: to Athens indeed without claiming any interest; to Sicyon without much hope of repayment; but no doubt to many others at a large profit.

He also undertook the publishing of books, buying slaves who were skilled copyists; and in this, as in so many other ways, his friendship was of infinite value to Cicero.

When we reflect that every highly educated man at this time owned a library and wished to have the last new book, we can understand how even this business might be extensive and profitable, and are not astonished to find Cicero asking Atticus to see that copies of his Greek book on his own consulship were to be had in Athens and other Greek towns.[100] This shrewd man also invested in gladiators, whom he could let out at a profit, as no doubt he would let out his library slaves.[101] Lastly, he owned houses in Rome; in fact he must have been making money in many different ways, spending little himself, and attending personally and indefatigably to all his business, as indeed with true and disinterested friendship he attended to that of Cicero In him we see the best type of the Roman businessman: not the bloated millionaire living in coarse luxury, but the man who loved to be always busy for himself or his friends, and whose knowledge of men and things was so thorough that he could make a fortune without anxiety to himself or discomfort to others.

What amount of capital he realised in these various ways we do not know, but the mass of his fortune came to him after he had been pursuing them for many years, in the form of a legacy from an uncle.
