At the height of summer, a blue-white sapphire-of-a-star appears near the top of the sky in the east at dusk, soon followed by a pale citrine point of starlight below. By 9:15 p.m. a third, dimmer star completes one of the season’s great celestial patterns, the Summer Triangle. The stars, Vega, Altair and Deneb, are among the brightest distant suns visible with the naked eye.
In Japanese lore, Vega is identified with the Sky King’s daughter, Orihime, the Weaving Princess, and Altair with Hikoboshi, The Cow Herder. At nightfall, when darkness is complete, the Silver River (Milky Way) courses between them. The enchanting and heart-rending tale spun about Orihime and Hikoboshi is the basis for Tanabata, or Star Festival, that is celebrated on July 7 or August 7, depending on how the 7th day of the 7th month is determined in the various localities in Japan and in Japanese communities around the world.
Tanabata was inspired by an ancient Chinese folktale and evolved out of other Asian traditions. The legend holds that Orihime wove beautiful cloth for her father, Tentei the Sky King. Alone on the banks of the Amanogawa, the Silver River of stars, she was sad with longing. In sympathy, her father introduced her to Hikoboshi and the two fell deeply in love. When they neglected their work, Tentei forbade them to see each other. They were separated, one on either side of the Silver River. Orihime’s despair at the loss of Hikoboshi moved her father to permit them one meeting a year. A version of the legend holds that magpies form a bridge across the river of stars one day each year, making it possible for the two to be together.
I was introduced to Tanabata by the Tribeca artist Naoto Nakagawa, in the following communication:
“I grew up learning about Tanabata, where two lovers are united only for this day meeting on the Silver River in the sky. In Japanese tradition, we visit a temple to receive wish paper to write our love wishes, then attach them to branches on the temple’s designated trees or bring them home with their good luck wishes hanging on a bamboo stick. On Tanabata that wish will come true. Tanabata is one of the most celebrated holidays in Japanese culture. With other Japanese parents, I used to go to our son’s school to teach kids about Tanabata.” Naoto Nakagawa www.naotonakagawa.com
To bring back the Milky Way, which is lost to light and air pollution in most areas where there is human habitation, we need Tanabata festivals all over the Earth, times of of celebration where the lights are turned down and eyes turn up to the sky.
