rest of Greece", and says that Philip V of Macedon associates himself with "the rest of the Greeks". In his text History of Rome, Livy states that the Macedonians, Aetolians and Acarnanians were "all men of the same language". Similar opinions are shared by Arrian, Strabo and Plutarch, who wrote of Aristotle advising Alexander "to have regard for the Greeks as for friends and kindred". M. B. Hatzopoulos points out that passages in Arrian's text also reveal that the terms "Greeks" and "Macedonians" were at times synonymous. For instance, when Alexander the Great held a feast accompanied by Macedonians and Persians, with religious rituals performed by Persian magi and "Greek seers", the latter of whom were Macedonians. Any preconceived ethnic differences between Greeks and Macedonians faded soon after the Roman conquest of Macedonia by 148 BC and then the rest of Greece with the defeat of the Achaean League by the Roman Republic at the Battle of Corinth (146 BC). The Persians referred to both Greeks and Macedonians as Yauna ("Ionians", their term for "Greeks"), though they distinguished the "Yauna by the sea and across the sea" from the Yaunã Takabara or "Greeks with hats that look like shields", possibly referring to the Macedonian kausia hat. According to another interpretation, the Persians used such terms in a geographical rather than an ethnic sense. Yauna and its various attributes possibly referred to regions to the north and west of Asia Minor, which could have included Phrygians, Mysians, Aeolians, Thracians, and Paionians in addition to Greeks. Overall, Persian inscriptions indicate that the Persians considered the Macedonians to be Greeks. In Hellenistic times, most Egyptians and Syrians included the Macedonians among the larger category of Greeks, as the Persians had done earlier. Modern discourse Modern scholarly discourse has produced several hypotheses about the Macedonians' place within the Greek world. Considering material remains of Greek-style monuments, buildings, inscriptions dating from the 5th century and the predominance of Greek personal names, one school of thought says that the Macedonians were "truly Greeks" who had retained a more archaic lifestyle than those living in southern Greece. This cultural discrepancy was used during the political struggles in Athens and Macedonia in the 4th century. This has been the predominant viewpoint since the 20th century. Worthington wrote, "... not much need to be said about the Greekness of ancient Macedonia: it is undeniable". Hatzopoulos argues that there was
