Altar of the Seven Stars

The Altar of the Seven Stars is the ritual structure Kong Ming constructs on Nanping Mountain to summon the southeasterly wind essential to the planned fire attack against Cao Cao. The episode makes the altar both a precisely arranged ceremonial space and the focus of a strategic crisis: after Kong Ming performs the rites, the wind arrives, and Zhou Yu interprets the result as evidence of dangerous supernatural power.

Purpose and Setting

During preparations for the confrontation with Cao Cao, Zhou Yu recognizes that fire is the best means of defeating him but is troubled by the absence of the wind needed to carry the attack. Kong Ming identifies that concern and offers to summon a southeasterly wind, asking for a special altar to be built on Nanping Mountain. He describes the intended effect as a wind that would blow for three days and nights, and Zhou Yu agrees to provide what is needed.

The site is chosen for its favorable feng shui. Kong Ming travels there with five hundred workers, 120 banner carriers, and Lu Su, turning the mountain into the setting for an operation on which the fire-ship plan depends. The altar links the battlefield’s practical requirements to a ritual performed away from the fleet: the ships are prepared, but the attack cannot proceed as intended without the wind.

Design and Ritual Arrangement

The completed structure is nine feet high and 240 feet in circumference, divided into three levels of three feet each. Red earth is brought for its construction. On the lowest level, the symbols of the twenty-eight constellations are arranged by direction: the green dragon to the east, the black turtle to the north, the white tiger to the west, and the red bird to the south. The middle level bears the symbols of the sixty-four hexagrams.

Four men in Daoist costume occupy the top level, each with a specified ritual role. One holds a feather-topped pole to detect the wind’s direction; another holds a pole marked with the seven stars for the same purpose. A third carries a sword, and the fourth an incense burner. This ordered arrangement makes the altar an instrument for observing and invoking the conditions the military plan requires, as well as a stage for Kong Ming’s rites.

The Rites and the Wind

When the altar is ready, Kong Ming fasts and bathes, then climbs it barefoot, his hair falling over his shoulders. He tells Lu Su he will do his best but asks not to be blamed if the rite fails. He lights incense, sprinkles water, and prays silently before withdrawing to rest. He repeats the procedure three times, but at first nothing happens.

Meanwhile, Zhou Yu and Lu Su wait at camp, where the fire ships are ready and Sun Quan’s fleet is holding position. Messengers have alerted Sun Quan and requested reinforcements, yet the wind still does not rise. During the third watch of the night, a strong southeasterly wind begins to blow. The timing resolves the immediate obstacle to the fire attack, while the preceding silence leaves the result open to interpretation: the narrative reports the ritual and the wind’s arrival, but does not explain the event in ordinary causal terms.

Strategic and Narrative Significance

The altar matters because it connects a military contingency to a scene of ritual action. Its measurements, directional symbols, and wind-detecting implements give the episode a detailed ceremonial structure; its purpose, however, is sharply practical. The wind is required for the fire ships, and its arrival shifts the balance from waiting to action.

The event also heightens the tension between Kong Ming and Zhou Yu. Rather than treating the wind simply as a successful contribution to their shared strategy, Zhou Yu becomes alarmed and concludes that Kong Ming must be allied with dark powers. He sends Ding Feng and Xu Sheng to Nanping Mountain to bring Kong Ming back. The altar thus marks a point where the plan’s success intensifies the rivalry between the strategists: what enables the military operation also makes Kong Ming appear to Zhou Yu as a threat.
