of Soli. This identification was founded on the fact that the philosopher Clearchus had written extensively on the morals and cultures of barbarian and Oriental cultures. Robert proposed that on a journey to research his literary subjects in more detail, Clearchus had stopped at Ai-Khanoum and set up his stele there. This theory was accepted as fact, and was often cited as an example of the purely Greek nature of Ai-Khanoum, and of the interconnected nature of the Hellenistic world. Later historians have dismissed Robert's hypothesis: Jeffrey Lerner noted that there is no evidence to support the assumption that Clearchus travelled to the eastern regions for research, as opposed to simply using a reference source; following Lerner, Rachel Mairs observed, knowing the philosopher's approximate date of death, that the placement of the stele in the sanctuary would have been a generation after the presumed journey; Shane Wallace, meanwhile, has noted that Klearchus was not an uncommon name, and so Robert's identification was improbable at best. All three propose instead that this Klearchus was a resident of Ai-Khanoum. Despite the refutation of Robert's theory, the stele still maintains its importance in modern analyses. The text of the epigram is poetic in its composition and vocabulary, echoing well-known Greek works such as Homer's Odyssey, Pindar's odes, and possibly even Apollonius' Argonautica. Mairs and Wallace have attributed the inscription and placing of the stele to "the first Bactrian-born generation" in the middle or late second century BC; they propose that this generation sought to define themselves as part of the wider Greek world by giving Ai-Khanoum legitimacy in the eyes of Delphi, itself a symbol of Hellenic unity. The poem also shares thematic elements with the Buddhist Edicts of Ashoka (inscribed in 260–232 BC); and Valeri Yailenko has proposed that it may have inspired them, suggesting a contribution of Hellenistic philosophy to the development of Buddhist moral precepts. Other buildings A gymnasium was located along the western ramparts. In its final architectural phase, it covered an area of , divided between a southern courtyard and a northern complex, and was accessible from both the palace district and a street running behind the riverside fortifications. There were three doors allowing entrance from the courtyard to a corridor which encircled the main complex. This comprised long rectangular rooms surrounding a square central courtyard, entered through four exedrae, one on each side; the exedra on the
