Imagery & Provenance意象与出处

Solar term

大寒 · Major Cold — "鸡使乳，鸷鸟厉疾，水泽腹坚。"

Imagery

A blackened purple, the colour of oil seen in shadow — the term’s darkest note.

Origin

Major Cold closes on the deepest colour of the year: a purple so dark it is almost black. The four purples have gone from a mansion in the sky to the ground to oil-drenched darkness — and the cycle of the 24 terms ends, ready to begin again.

System

Book of Rites, Monthly Ordinances: “On the day of Major Cold, hens begin to brood.” (combining colour of 大寒.)
