Wak'as
Wak'as were spots of ceremonial, ritual, or religious significance arranged along pathways called siq'is. Some wak'as were natural features, such as springs, boulders, or caves, while others were man-made features like buildings, fountains, or canals. The number of wak'as on each line varied, typically from 3 to 13 or more per siq'i. Certain people from specific kin groups were designated as caretakers for each wak'a.Organization
The siq'i lines originate at the Qurikancha and travel, in relatively straight pathways, to the edges of the land added to the Inca empire by Pachakuti.Farrington 1992 (p. 370) Four of the lines correspond to four main branches of the Inca road system. Every line was tended to by a particular social group, and the line's character was determined by the wak'as that fell along its path and what could be sacrificed there, calendric and astronomical events associated with it, and sometimes a description of the environment it passed through. The location of the wak'as appears to dictate the path of the siq'i line, not the other way around. Siq'is may be relatively straight or have segments that are straight, but the paths frequently curve or zigzag. However, siq'i lines do not generally cross over one another. The lines are also thought to show the social and political organization of Cusco, specifically the Inca and non-Inca ''Siq'i lines and ritual
Some aspects of the siq'i system remain unclear. R. Tom Zuidema has theorized that the wak'as may be related to Incan understanding of astronomy. The Inca followed a synodic lunar calendar (time was measured in phases of the moon). They observed periodic calendrical rituals celebrating events such as solstices, and different centers were used for different astronomical events. As an extension of this theory, Zuidema proposed that each of the 328 wak'as may represent one day in the year, the time for the Moon to complete 12 circuits, and that some of the siq'is were used for astronomical sight lines.Bauer 1992 187-202.See also
