Fasting and purification were necessary before undertaking solemn sacrifice of any kind. Thus the King of Ts'u in 690 B.C. did this before announcing a proposed war to his ancestors; and an envoy starting from Ts'u to Lu in 618 reported the circumstance to his own particular ancestors, who may or may not have been (as many high officers were) of the reigning caste. On another occasion the ruler of Lu was assassinated whilst purifying himself in the enclosure dedicated to the god of the soil, previous to sacrificing to the _manes_ of an individual who had once saved his life. Practically all this is maintained in modern Chinese usage. A curious distinction is mentioned in connection with official mourning tidings in the highly ritual state of Lu. If the deceased were of a totally different family name, the Marquess of Lu wept outside his capital, turning towards deceased's native place, or place of death; if of the same name, then in the ancestral temple: if the deceased was a descendant of the same founder, then in the founder's temple; if of the same family branch, then in the paternal temple. All these refinements are naturally tedious and obscure to us Westerners; but it is only by collating specific facts that we can arrive at any general principle or rule. [Illustration: MAP 1. Ts'u's five capitals, in order of date, are marked. In 504 B.C. the king had to leave the Yang-tsz for good in order to escape Wu attacks. In 278 B.C. Ts'in captured No. 4, and then the ancient Ch'ta capital (No. 5, already annexed by Ts'u) became the Ts'u capital (see maps showing Ch'en's position). Ts'u was now a Hwai River power instead of being a Han River and Yang-tsz power. Shuh and Pa are modern Sz Ch'wan, both inaccessible from the Han system. The Han system to its north was separated from the Wei system and the country of Ts'in by a common watershed. 2. Wu seems to have been the only power besides Ts'u possessing any knowledge of the Yang-tsz River, and Wu was originally part of, or vassal to Ts'u. 3. Pa had relations with Ts'u so early as 600 B.C. Later Pa princesses married Ts'u kings.] CHAPTER XIII ANCIENT DOCUMENTS FOUND
