Imagery & Provenance意象与出处

Solar term

立秋 · Start of Autumn — "凉风至，白露降，寒蝉鸣。"

Imagery

From the “Song of Chile”: “the sky is cang-cang, the wilderness vast.” A dark, muted blue.

Origin

The line is one of the oldest landscapes in Chinese poetry — sky and steppe seen as one enormous stretch of cang. As the turning colour it is the term’s blue grown deep rather than bright: distance, height, and the onset of cold.

System

B Solar-term sets

Source

Book of Rites, Monthly Ordinances: “On the day of Start of Autumn, cool winds arrive.” (turning colour of 立秋.)

Citation

《礼记·月令》：立秋之日，凉风至。

Evidence

Ancient-text attestation (attestation > artifact > compilation > approximation)
