Ceibal is located on the Pasión River in southwest Peten, Guatemala. From 1964 to 1968, Harvard University's Seibal Archaeological Project conducted investigations at the site (Willey et al. Reference Willey, Ledyard Smith, Tourtellot and Graham1975). The Harvard project discovered an Early Middle Preclassic (c. 1000–700 BC) occupation and defined the associated Real ceramic phase (Sabloff Reference Sabloff1975).
From 2005 to 2016, the Ceibal-Petexbatun Archaeological Project, directed by Takeshi Inomata and Daniela Triadan, conducted additional excavations at Ceibal, focusing on the origins of Maya society (Figure 1). Based on these excavations, Inomata refined Sabloff's ceramic chronology (Table 1; Inomata Reference Inomata2017). Ceibal was founded around 950 BC, when the Central Plaza and the first platforms were carved out of the bedrock (sterile limestone marl and clay; Inomata et al. Reference Inomata, Triadan, Aoyama, Castillo and Yonenobu2013). The foundation of this public space roughly coincides with the transition to sedentism and ceramic use in the Maya lowlands (Lohse Reference Lohse2010). Greenstone axes and other objects were repeatedly cached in the plaza (Inomata, Pinzón, et al. Reference Inomata, Pinzón, Palomo, Sharpe, Ortíz, Méndez and Román2017). The earliest known house platforms at Ceibal date to the Real 3 ceramic phase (c. 775–700 BC), although earlier domestic structures may exist (Inomata et al. Reference Inomata, MacLellan, Triadan, Munson, Burham, Aoyama, Nasu, Pinzón and Yonenobu2015; Triadan et al. Reference Triadan, Castillo, Inomata, Palomo, Méndez, Cortave, MacLellan, Burham and Ponciano2017).

The Karinel Group is a residential platform 160 m west of the Central Plaza (Figure 1). The area was investigated by Gair Tourtellot during the 1960s (Tourtellot Reference Tourtellot1988:171–174). Tourtellot found that the platform was occupied during the Real ceramic phase and that the bedrock was relatively near the ground surface. For those reasons, the Karinel Group was an ideal location to expose Early Middle Preclassic domestic areas. I oversaw excavations there from 2012–2015. The team established the chronology of the Karinel Group through the analysis of stratigraphy, ceramic artifacts, and radiocarbon dates (Inomata, Triadan, MacLellan, et al. Reference Inomata, Triadan, MacLellan, Burham, Aoyama, Palomo, Yonenobu, Pinzón and Nasu2017:Table S1). I found that early domestic rituals were distinct from activities in the Central Plaza, until a transformation in ritual practices took place at the beginning of the Late Preclassic. Comparisons to published reports show that Ceibal's early household rituals had more in common with rituals in the Belize River Valley region than with those in northern Belize.
Investigations at the Karinel Group
Early Middle Preclassic
Throughout the Early Middle Preclassic and the beginning of the Late Middle Preclassic, the residents of the Karinel Group used the bedrock as a living surface. At some point during the Early Middle Preclassic, the northern edge of the basal platform was defined by carving the natural soil (Subop. 211C). The earliest evidence of occupation consists of Real 2 phase (c. 850–775 BC) ceramic artifacts found in deposits on the bedrock (Subops. 211A and 211D). A charcoal sample found on the bedrock (PLD-28792) was also dated to this era (Inomata, Triadan, et al. Reference Triadan, Castillo, Inomata, Palomo, Méndez, Cortave, MacLellan, Burham and Ponciano2017:Table S1).
During the Real 3 phase, the basal platform was extended to the north. Poorly preserved walls in this area indicate the existence of Real 3 structures, and middens suggest that the structures were domestic. A low circular platform or altar, Structure Pemech-2, measured 2.8 m in diameter (Figures 2 and 3). Near the end of the Real 3 phase, Ceibal Monument 3, a roughly modified boulder, was placed above Structure Pemech-2. Monument 3 measures approximately 1 m3 and may have served as an altar. It was incorporated into later structures and remained visible throughout the Preclassic period. A similar boulder was excavated in an Early Middle Preclassic residential area at Cahal Pech in the Belize River Valley (Cheetham Reference Cheetham, Healy and Awe1995:27).

Burial 132 was deposited in a globular chamber in the bedrock on the western side of the Karinel Group (Subop. 211B). The burial contained two adults, an infant, and seven Real 3 ceramic vessels (Palomo et al. Reference Palomo, Inomata and Triadan2017).
Fragments of ceramic figurines were recovered from Real 3 and Late Middle Preclassic middens and construction fills at the Karinel Group. Most of these figurines depict human forms. Middle Preclassic figurines may have been used in domestic rituals (Grove and Gillespie Reference Grove, Gillespie and Plunket2002; Marcus Reference Marcus, Grove and Joyce1999).
Late Middle Preclassic
Middens confirm that the Karinel Group remained residential throughout the Late Middle Preclassic period. The earliest clear patio dates to the Escoba 1 phase, when an area of the natural soil in the northeast part of the group was leveled (Subop. 211C). On the east side of the patio, a white marl platform was constructed. This was rebuilt as a mottled red-and-white platform. Each of these structures was only a few centimeters thick. One posthole was uncovered.
During the Escoba 2 phase (c. 600–450 BC), the red-and-white platform was covered by Structure Saqb'in-1, a platform with walls made of limestone blocks. A circular platform, Structure Sutsu, was built in the patio, 1.6 m west of Structure Saqb'in-1 (Figures 2 and 3). It is about 0.4 m tall and 5 m in diameter, and the outer wall is made up of two concentric rings of limestone blocks. There is no evidence of a superstructure. During the Late Middle Preclassic, similar circular platforms were constructed within domestic patio groups throughout the lowlands and probably served as stages for ritual performances (Aimers et al. Reference Aimers, Powis and Awe2000; Hendon Reference Hendon2000).
Around the same time, the basal platform of the Karinel Group was extended to the west with the addition of Structure Tz'unun. A midden in this area contained the remnants of obsidian prismatic blade manufacture (Aoyama et al. Reference Aoyama, Inomata, Triadan, Pinzón, Palomo, MacLellan and Sharpe2017). At the end of the Escoba 2 phase, an offering (Cache 157) of an obsidian blade, an obsidian flake core, and a large fragment of a ceramic plate was left on the floor of Structure Tz'unun and covered by construction fill. Late Middle Preclassic caches of obsidian objects, associated with construction episodes, have also been found at Cahal Pech (Lee Reference Lee, Healy and Awe1996:85; Lee and Awe Reference Lee, Awe, Healy and Awe1995:107). At nearby Blackman Eddy, a partial ceramic vessel and shell fragments were left on the floor of a house platform (Brown et al. Reference Brown, Awe, Garber, Kathryn Brown and Bey2018:100). No Middle Preclassic caches were identified at Cuello and K'axob in northern Belize (Hammond Reference Hammond1991; McAnany Reference McAnany2004).
Below Structure 47 (Subop. 211F), we uncovered another round platform dated to the Escoba 2 phase: Structure 47-Sub-3. The wall of 47-Sub-3 is made up of white, soft limestone blocks and is 0.20 m tall (Figure 2). Its diameter is approximately 6 m.
During the Escoba 3 phase (c. 450–350 BC), a western extension of the basal platform was constructed over Structure Tz'unun, and a human scapula was left in a retaining wall. Two house platforms, Structure Pemech-1 and Structure Ayiin, were built on the east and west sides of the patio north of Structure Sutsu (Figure 3). These platforms were rectangular, with walls made of multiple courses of limestone blocks.
Middle Preclassic mortuary rituals at Ceibal differ greatly from those at K'axob (McAnany Reference McAnany2004) and Cuello (Hammond Reference Hammond1991), where many burials were found in house platforms. Two burials at the Karinel Group are tentatively dated to the Escoba 2 ceramic phase, although they may be older. Neither contained grave goods. As with Burial 132, these burials were not located in house platforms. Burial 128, of an adult, was found on the bedrock outside Structure Tz'unun. It was a primary burial of an adult, but the skull, left arm, both tibias, and the right femur were removed in antiquity. Two teeth were recovered. Burial 160 was found on the bedrock below Structure Sutsu, but does not appear to be intrusive into that structure (Figure 3). It was located near the edge of Structure Sutsu, and its orientation does not relate to known architecture. Like Burial 128, this is a primary burial of an adult. The body was cut in half postdeposition, with removal of the right side of the body and the entire skull. Two teeth remained.
Middle to Late Preclassic Transition
Based on excavations at the Karinel Group and investigations by Melissa Burham in the periphery of Ceibal, rituals in residential groups became similar to those conducted in the public plaza around the time of the transition to the Late Preclassic period (Burham and MacLellan Reference Burham and MacLellan2014). At the Karinel Group, the early patio group was filled in around 350 BC. Above the buried house platforms, an offering of a human ilium and the first cache of a complete ceramic vessel (Cache 175) were deposited in pits in an exterior floor.
Late and Terminal Preclassic
During the Cantutse 1 ceramic phase (c. 350–300 BC), Structure 47-Sub-3 was replaced by the rectilinear Structure 47-Sub-2. Above the buried Middle Preclassic patio group, Structure 45a-Sub-1, a platform with a front terrace, faced south toward a plaster patio floor. Monument 3 was still visible within the platform.
During the Terminal Preclassic (Protoclassic) period (c. 75 BC–AD 300), Cache 159 was deposited on the bedrock in front of Structure 47. It contained 18 ceramic vessels placed lip to lip, an obsidian blade, and 2 limestone discs. Cache 159 dates to the Xate 1 or 2 ceramic phase and resembles Terminal Preclassic caches in the Central Plaza (Inomata, Pinzón, et al. Reference Inomata, Pinzón, Palomo, Sharpe, Ortíz, Méndez and Román2017).
Conclusions
Data from the Karinel Group complement information from Ceibal's Central Plaza and from early sites in other regions of the Maya lowlands. During the Middle Preclassic period, public rituals had little in common with domestic rituals at Ceibal. In the plaza, many caches were cut into the floors, whereas domestic rituals may have involved circular platforms and ceramic figurines. Rituals at the Karinel Group differ markedly from practices at early residential groups in northern Belize. Greater similarity is found between the Karinel Group rituals and the household rituals at sites in the Belize River Valley. After the transition to the Late Preclassic, the residents of the Karinel Group created intrusive caches that resembled contemporaneous deposits in the Central Plaza. Figurines became rare, and circular structures were buried. This shift coincides with changes in ritual practices across the lowlands (Ringle Reference Ringle, Grove and Joyce1999). The Karinel Group findings encourage new inquiries into variations in household ritual across the Maya area and over the course of the Preclassic period.
