During the mid-fifth century BCE, the Telesterion at Eleusis remained in ruins following its destruction by Persian invaders a generation earlier.<ref name="Shear">Shear, T. Leslie Jr. "Chapter 6: The Telesterion at Eleusis." ''Trophies of Victory: Public Building in Periklean Athens'', Princeton University Press, 2016, pp. 255–287. [https://www.jstor.org/stable/j.ctt17xr50c.11 JSTOR].</ref> Visitors at the time would have observed both residual damage and partial repairs. Although the mud-brick wall had been breached by Persian battering rams, it had since been patched. A new section was also added to the northeast, designated for sanctuary-related functions.<ref name="Shear" />

Between 478 and 450 BCE, the central terrace remained largely unchanged. At the time of the Persian attack, the sanctuary had been undergoing reconstruction; the archaic Telesterion had already been dismantled and a new version was only in the early stages of construction.<ref name="Shear" /> As a result, the Telesterion was left unfinished and deteriorated for several decades.

Unlike typical Greek temples, the Telesterion, while serving as the central sacred space of the [[Eleusinian Mysteries]], was architecturally more similar to a performance hall than to structures like the Parthenon.<ref name="Shear" /> The term “Telesterion,” commonly used today, derives from [[Plutarch|Plutarc]]<nowiki/>h, though it was rarely used in antiquity. In official fifth-century inscriptions, the structure was referred to as the “Eleusinion.”<ref name="Shear" />

Among the religious cults affected by the Persian sack of Attica, the cult of Demeter at Eleusis was likely the most disrupted, given its heavy dependence on rituals conducted inside the sanctuary. The Mysteries relied on indoor ceremonies, including the secret initiation rites during which the hierophant revealed sacred objects of the cult. These were housed in a special inner chamber known as the Anaktoron, the most sacred space of the temple.<ref name="Shear" /> Due to the centrality of this site, it is likely that a temporary structure was erected on the ruins of the original Telesterion. This would have been a light construction, leaving no surviving physical remains. Archaeological evidence suggests that this makeshift building was located on the northeastern half of the site. When large-scale construction resumed under [[Pericles]], it began on the southwestern side, behind the Anaktoron, an area previously left untouched.<ref name="Shear" />

Before the mid-fifth century BCE, the Eleusinian sanctuary was in a poor state. It may not have even had a secure space to protect its sacred treasury. Instead, the funds dedicated to Demeter and Persephone were stored on the Athenian [[Acropolis]] alongside the treasury of Athena, indicating that Eleusis lacked a safe depository of its own.<ref name="Shear" />

This situation began to change when Athens, as part of its broader Panhellenic ambitions, promoted the Eleusinian Mysteries as a unifying religious institution.<ref name="Shear" /> Plans likely emerged to rebuild and expand the Telesterion. The first concrete step came with a decree proposed by a man named Thespieus, which reorganized the administration of the sanctuary. The decree established a board of five supervisors, known as [[Epistates|epistatai]], one of whom would serve as secretary. These officials were tasked with managing all financial and property matters concerning Demeter and Persephone, not only in Eleusis, but also in shrines located in Athens and the port of Phaleron.<ref name="Shear" />

The epistatai were empowered to collect outstanding debts, recover lost property, and manage the goddesses’ income, in consultation with the priests and the Athenian council (boulē). After the new board was formed, a state audit was conducted to examine financial records from the sanctuaries in Eleusis, Athens, and Phaleron. No architects were consulted regarding the Eleusinian sanctuary during this audit, suggesting that no major building projects had yet begun at Eleusis.<ref name="Shear" /> Nonetheless, the scale of the administrative reorganization suggests that large-scale construction, namely, the rebuilding of the Telesterion, was imminent.

Thespieus’s amendment likely supplemented an earlier, now-lost decree that had authorized the Telesterion’s reconstruction. He granted the epistatai significant authority and access to financial resources to carry out the project. The epistatai became the long-term administrators of the sanctuary, holding this role for over a century. Although they were initially appointed annually, their terms and numbers varied over time, which was typical for Athenian civic offices. Despite such changes, they retained their original responsibilities, which included financial oversight, supervision of construction, and maintenance of detailed records.<ref name="Shear" />

Surviving inscriptions from their archives include inventories of sacred objects, grain offerings, and contracts related to building activities. The epistatai were responsible for hiring architects, paying workers, and publishing accounts of construction expenses. These projects included new walls, gates, and entrances, especially those associated with the Telesterion. Ultimately, the epistatai served as the key officials responsible for the successful rebuilding of the Telesterion in the classical period.<ref name="Shear" />

=== Influence of Acoustics on the Ritual Experience ===
The Telesterion was a square, pillared, and spacious hall with seating arranged in eight rows, similar to an amphitheater, and it could accommodate up to 5,000 people. It featured six hallways leading to six separate entrances. The building resembled a theater, though without a stage, and had the Anaktoron, the most sacred chamber, at its center. Adjacent to it stood the marble throne of the [[Hierophant]], the chief priest of the Mysteries.<ref name="Dreni">Dreni, Stella, and Panagiota Avgerinou. "The Acoustics of the Eleusinian Telesterion." In ''Archaeoacoustics: The Archaeology of Sound'', 2014, pp. 143–152. [https://eleusinianmysteries.org/wp-content/uploads/2025/01/The-Acoustics-of-the-Eleusinian-Telesterion.pdf Full text].</ref>

Sound propagation within large architectural spaces faces several challenges. First, sound weakens as it travels over distance. Second, sound energy diffuses in multiple directions, causing reverberation. Third, tall spaces can produce echoes. Fourth, spacious and empty interiors lack sound-absorbing surfaces, which can diminish clarity. The Telesterion overcame these obstacles through thoughtful architectural choices and materials. Its walls were constructed with resonant stone, allowing for a bold, amplified sound. The walls of the Anaktoron also reflected and reinforced sound between speakers and their audience. The interior columns enhanced echo effects, while the stepped seating contributed to sound reflection back into the space. The roof, made of wood, a naturally sound-absorbing material, reflected only part of the sound energy, helping modulate the acoustics further.<ref name="Dreni" />

Additionally, heat from torchlight affected how sound traveled. Heat produces layers of air with differing densities, which in turn alter the reflection and refraction of sound waves. These combined physical effects produced an acoustically dynamic and unstable auditory experience, intensifying the emotional impact of ritual proceedings.<ref name="Dreni" />

Sound was central to this experience. The fear of the underworld was simulated through darkness and eerie sounds, including a metal drum that may have mimicked the wailing of Persephone during her abduction, or the echo of Demeter’s call across land and sea. The performance concluded with chants, the raising of torches, and finally, a moment of profound silence as the priest revealed a wheat ear, regarded as Demeter’s most sacred gift.<ref name="Dreni" />

All of these physical dynamics contributed to a complex and immersive auditory experience that heightened the emotional impact on the initiates. Throughout all three phases of the ceremonies, instrumental sounds were used to produce unnatural effects that amplified the mystical atmosphere. These sounds helped create the impression that otherworldly entities were present during the rituals.<ref name="Dreni" />

=== Sensory Framing of the Deiknymena ===
[[File:Priest - Regina vasorum.jpg|thumb|Drawing of Elusinian Priest]]
The walls and roof of the Telesterion created a visually enclosed and darkened environment that shaped the sensory experience of the initiates during the Deiknymena.<ref name="Scott">Scott, Michael. "Walls and the Ancient Greek Ritual Experience: The Sanctuary of Demeter and Kore at Eleusis." In ''Cognitive Approaches to Ancient Religious Experience'', edited by Esther Eidinow and Armin Geertz, Cambridge University Press, 2022, pp. 193–217. [https://wrap.warwick.ac.uk/id/eprint/161151/1/WRAP-Walls-and-the-Ancient-Greek-ritual-experience-the-sanctuary-of-Demeter-and-Kore-at-Eleusis-Scott-2022.pdf PDF].</ref> During this ritual, sacred objects were presented to them. These conditions are believed to have amplified a sense of group cohesion, as participants were physically gathered in close proximity with limited individual visibility. The darkness likely obscured the view of the rituals about to take place, while the seating arrangement, facing inward toward the center of the hall, reinforced the feeling of collective participation in a shared experience.<ref name="Scott" />

This inward-facing architecture concentrated visual attention toward the center, where the ritual climax occurred. At the height of the ceremony, sacred objects were revealed by the hierophant, often accompanied by a sudden burst of light. This dramatic shift from darkness to brightness would have had a strong sensory and emotional impact, momentarily overwhelming the initiates’ vision and limiting their ability to clearly see the objects being displayed.<ref name="Scott" />

Additionally, the Telesterion’s internal columns created partial obstructions, further interrupting lines of sight to the central ritual space. These architectural features contributed to a deliberate manipulation of visual perception, heightening the mystery of the experience. As visual clarity was restricted, initiates were prompted to rely more heavily on their sense of hearing, an effect that worked in tandem with the Telesterion’s acoustics to shape the ritual encounter.<ref name="Scott" />
