After this little ceremony of coming of age, a number of the young men apparently did nothing. The sons of poorer parents have long ago gone to their work in their various trades. Those of the more well-to-do may--and, if they are afterwards to seek public office, they must--now undertake military service amid the conditions which are to be described in the next chapter. Others, being of a more studious turn, will proceed to complete their education by going abroad to one or other of the great seats of philosophic study which corresponded to our universities. Philosophy meant to the Roman a guide to the direction of life. Roman religion, upon which we shall hereafter dwell in some detail, consisted of a number of forms and ceremonies, or acts of recognition paid to the deities; it embodied certain traditional principles of duty to family and state; but otherwise it exercised very little influence on the conduct of life. So far as such guidance was supplied at all, it was by moral philosophy, the treatment of which, as it was understood at this date, is bound up with that of religion and must wait till we reach that subject. It is true that there were professional teachers of philosophy at Rome itself, but the metropolis was not their chief resort, any more than, until recently, London would have been recognised as a seat of university learning of the front rank. It is also true that many great houses maintained a domestic philosopher, who not only helped in moulding the tone of the master of the house and afforded him intellectual company, but might act as private philosophic tutor to his son. But for the most part this highest instruction was rather to be sought in cities specially noted for their assemblage of professors and lecturers. Chief among these figured Athens, Rhodes, Tarsus, Antioch, Alexandria, and Marseilles. At Naples also might be found a large number of men of learning, but they were chiefly persons who had retired from professional life, and who chose that city because of its pleasant climate and surroundings, and because they could there enjoy each other's society. In some of the cities named--particularly Athens and Alexandria--there were endowed professorships (though not endowed by the Roman emperors) of which the benefit was enjoyed, not only by the local student but also by those from other parts of the Roman world who chose to resort to such established teachers. This does not mean that such students paid no fee, nor that there was any lack of lecturers unendowed. The student was free to take his choice. Where there was endowment, as at Athens, there was control by the local authorities over the behaviour of students and also of their teachers; but it is evident that a professor's audience was by no means always a very well-ruled or docile body. As in the German universities, the visiting students were men, and some of them fairly advanced in years, and, also as in Germany, they followed their own tastes in study and
