Why did the romans adopt the greek gods instead of coming up with their own?

To answer this question we have to think about the characters of the Greek and Roman civilizations. The Greeks were a culturally prolific civilization that carried out a process called Hellenization. It consisted in transferring his belief system to the people who were nearby. In this case, we can not think in territorial terms but rather in cognitive terms. The Greek culture was absorbed because it was valid in itself. When the Romans invaded Greece, a warlike people accustomed to surviving, they knew how to preserve the features of the Greek culture that worked to maintain peace in their "colonies".

Then, although the Romans conserved the pantheon of gods of Greek origin, they re-baptized them, attributing to them relations with their own history, the history of Rome. Hence arises the well-known myth of the founding of Rome, in the hands of Romulus (and his brother Remus) who were direct descendants of Mars (god of war) who found his Greek equivalent in the god Ares.

now, of course, the quality and the seasonability of these winter dreams varied, but the stuff of them remained.   they persuaded dexter several years later to pass up a business course at the state university—his father, prospering now, would have paid his way—for the precarious advantage of attending an older and more famous university in the east, where he was bothered by his scanty funds. but do not get the impression, because his winter dreams happened to be concerned at first with musings on the rich, that there was anything merely snobbish in the boy. he wanted not association with glittering things and glittering people—he wanted the glittering things themselves. often he reached out for the best without knowing why he wanted it—and sometimes he ran up against the mysterious denials and prohibitions in which life indulges.

there you go thats what we are missing

"the tune the he might never know again." this part build anticipation. dexter got extremely happy by the piano tune. he could see what he was living at that moment in his life throught this feeling. the reader might want to learn more about his happy life. in fact, he called it a state of   'ecstasy'. the fact that he had got in a mood of intense appreciation and that everything about him was extremely bright and glamorous might lead the reader to feel that this state of happiness may not last long. the two parts from the excerpt that exemplify the anticipation are: " the sound of the "; " it was a know again."
