few vessels may be represented. Sherd-fits were not achieved.

Designs are executed on convex surfaces in a dull and washy dark brown (5YR 2.5/2, 5YR 3/2-3, 2.5YR 2.5/2, or 2.5YR 3/4 where very thin), with some variation on different parts of the sherd. Background slip colours include creamy grey-brown (5YR 4/2-3), an orange (5YR 5/3) a greyish blue (7.5YR 3/0 to 7.5YR 4/2) and 2.5YR 5/6. This variation is apparently the result of uneven firing. Many sherds have a black fabric core. The most common motif is a grid pattern of lines from 2 to 6 mm, and also an oval, semicircle or wavy line. Geometric and curvilinear motifs occur together on some sherds (App.II Figs. 9c- p,r,s,u,z,aa).

(d) AL39 Summary.

AL39 was clearly a focus of substantial occupation and of agricultural activities. It stands in stark contrast to the sporadic and minimal present use of the lower Apurimac area.

Cusco Inca pottery comprises 46% of the painted pottery (CID + CIP) in the Cl-4 collections at AL39, the best known Cusco Plain vessel was well

represented by distinctive sherds and probably a number of the unpainted body sherds group. Qopa pottery (QA and QB) comprises 50% of painted sherds. It is important in the Apurimac region because previous information from the nearest reported area (Curawasi) suggested that only unpainted pottery of non-Inca wares was likely to be found [Rowe 1956:1433.

QB decoration style is not highly distinctive, but the combination of geometric and curvilinear or figurative elements in QA permits comparison with published material and collections. QA decoration is similar to that reported from the surface at Choquepata Piscaycucho, site of circular, oval and straight­ sided structures but no Cusco Inca architecture, in the neighbouring Urubamba Valley [Kendall 1985:313-314, Fig. 6 If]. There are similarities to Killke geometric motifs (see App.II Fig. 9c), and exterior rim thickening on flaring neck vessels (App.II Fig. 7c). The pottery is not out of place amongst that of the Late Prehistoric Tradition.

Settlement at Sector A and construction of terraces of Sector 3 probably pre-date Inca influence in this area. It is possible that the structures and some terraces in Sector A date to the Inca period. Its Inca period occupants

were s u f f i c i e n t l y ti e d to th e s t a t e to have had a c c e s s to a la r g e ra n g e o f Inca p o t t e r y w a re s, in c lu d in g d e c o ra te d and d o m e stic v e s s e ls .
