In his first-century BCE treatise De architectura, Vitruvius described the placement of bronze acoustic vases (echea) in ancient Greek theaters, asserting that these resonant vessels were tuned to specific musical intervals to amplify actors' voices. For centuries, classical scholars accepted this description at face value. However, mid-twentieth-century architectural historians began expressing skepticism, noting the complete absence of intact bronze echea in the archaeological record of surviving Hellenistic theaters. They argued that Vitruvius had merely compiled theoretical Greek acoustic treatises—most notably those of Aristoxenus—without empirical verification of actual construction practices. Recent acoustic analyses of the theater at Epidaurus suggest an alternative explanation: the extraordinary clarity of sound was achieved not through artificial amplification devices, but through the filtering properties of the limestone seating tiers, which selectively dampened low-frequency background noise while reflecting high-frequency vocal signals. While this finding demonstrates that Greek architects achieved acoustic optimization through geometry and materials rather than bronze resonators, it does not entirely disprove the historical existence of echea. It does, however, suggest that if such vessels were used, their function was likely symbolic or localized rather than essential to whole-venue amplification.

Based on the passage, which of the following can be inferred regarding Vitruvius’s account of ancient Greek theater acoustics? Consider each of the three choices separately and select all that apply.
