human figuresâ€? across the facade (1924:213). At the west end of the front facade two masks, one above the other, still span the distance between the medial molding and the upper three member cornice. These masks are small in size and poor in workmanship. In the adjacent panel, three discs similar to the larger types from the North Colonnade and adjacent structure 3D6 were arranged in a vertical row. The disc decorations from the facades of these three structures may reflect a desire to bring harmony to the appearance of contiguous structures, and they probably also imply a close chronological relationship. The superimposed mask panels most likely derive from the superimposed mask panels of the facade of the Temple of the Warriors, and an earlier structure like the Upper Temple of the Jaguars might have inspired the serpent guilloche of the medial molding.
traced to the Chac Mool Temple, the Temple of the Warriors, and the Northwest Colonnade. Figure 4E (Ricketson 1927:11, Tozzer 1957:Fig. 670), for example, while similar to figures from the south bench of the Chac Mool Temple (Morris 1931:Pl. 133, Tozzer 1957:Fig. 671), also resembles the figure on column 39S in the Northwest Colonnade (Morris 1931:Pl. 105, Tozzer 1957:Fig. 669). The famous snake handler sculpture, column 1S (Ricketson 1927:13, Tozzer 1957:Fig. 658), resembles a similar treatment on column 10S from the Temple of the Warriors (Morris 1931:Pls. 50, 67) and columns 8E, 51N and possibly 4W from the Northwest Colonnade (Morris 1931:Pls. 76, 115, 72). The adjacent sculpture, column 1W (Tozzer 1957:Fig. 663), resembles another figure from the south bench of the Chac Mool Temple (Tozzer 1957:Fig. 660), but closer similarities seem to be with columns 56S and 52S from the Northwest Colonnade (Tozzer 1957:Figs. 661, 662) and with sculptured figures from the south side of the dais in the same structure (Tozzer 1957: Fig. 664).
The sculptured columns and associated altar within the colonnade, and not the faĂ§ade, provide the best evidence that this is a late structure (Ricketson 1927). Of the four sculptured columns, the two around which the massive altar was built have a single human figure on each column face. The two sculptured columns in front of the altar, in addition to a central human figure, have minor panels at the top and bottom of each column face. As a group, these sculptures most resemble the sculptures from the temple on the northeast bank of the Xtoloc Cenote, structure 3D13 (Ruppert 1952:Figs. 134-136), but individual figures on the columns can be
These comparisons underscore the difficulty of assigning the Northeast Colonnade or the Xtoloc Temple to the period either of the Chac Mool Temple or the Temple of the Warriors solely on the basis of the subject matter of the sculptures. Evidence from the minor panels above and below the central figures of columns 1 and 2 may be brought to bear here. The placement of the jaguar-serpent-bird motif at the base of these two columns suggests affinity
