Polybius was considered a poor stylist by Dionysius of Halicarnassus, writing of Polybius' history that "no one has the endurance to reach [its] end". Nevertheless, clearly he was widely read by Romans and Greeks alike. He is quoted extensively by Strabo writing in the 1st century BC and Athenaeus in the 3rd century AD. His emphasis on explaining causes of events, rather than just recounting events, influenced the historian Sempronius Asellio. Polybius is mentioned by Cicero and mined for information by Diodorus, Livy, Plutarch and Arrian. Much of the text that survives today from the later books of The Histories was preserved in Byzantine anthologies. His works reappeared in the West first in Renaissance Florence. Polybius gained a following in Italy, and although poor Latin translations hampered proper scholarship on his works, they contributed to the city's historical and political discourse. Niccolò Machiavelli in his Discourses on Livy evinces familiarity with Polybius. Vernacular translations in French, German, Italian and English first appeared during the 16th century. Consequently, in the late 16th century, Polybius' works found a greater reading audience among the learned public. Study of the correspondence of such men as Isaac Casaubon, Jacques Auguste de Thou, William Camden and Paolo Sarpi reveals a growing interest in Polybius' works and thought during the period. Despite the existence of both printed editions in the vernacular and increased scholarly interest, however, Polybius remained an "historian's historian", not much read by the public at large. Printings of his work in the vernacular remained few in number—seven in French, five in English (John Dryden provided an enthusiastic preface to Sir Henry Sheers' edition of 1693) and five in Italian. Polybius' political analysis has influenced republican thinkers from Cicero to Charles de Montesquieu to the Founding Fathers of the United States. John Adams, for example, considered him one of the most important teachers of constitutional theory. Since the Age of Enlightenment, Polybius has in general held appeal to those interested in Hellenistic Greece and early Republican Rome, while his political and military writings have lost influence in academia. More recently, thorough work on the Greek text of Polybius, and his historical technique, has increased the academic understanding and appreciation of him as a historian. According to Edward Tufte, he was also a major source for Charles Joseph Minard's figurative map of Hannibal's overland journey into Italy during the Second Punic War. In his Meditations On
