and magical arts in general.

3. LIU T`AO, in 6 CHUAN, or 60 chapters. Attributed to Lu
Wang (or Lu Shang, also known as T`ai Kung) of the 12th century
B.C. [74] But its style does not belong to the era of the Three
Dynasties. Lu Te-ming (550-625 A.D.) mentions the work, and
enumerates the headings of the six sections so that the forgery
cannot have been later than Sui dynasty.

4. WEI LIAO TZU, in 5 CHUAN. Attributed to Wei Liao (4th
cent. B.C.), who studied under the famous Kuei-ku Tzu. The work
appears to have been originally in 31 chapters, whereas the text
we possess contains only 24. Its matter is sound enough in the
main, though the strategical devices differ considerably from
those of the Warring States period. It is been furnished with a
commentary by the well-known Sung philosopher Chang Tsai.

5. SAN LUEH, in 3 CHUAN. Attributed to Huang-shih Kung, a
legendary personage who is said to have bestowed it on Chang
Liang (d. 187 B.C.) in an interview on a bridge. But here again,
the style is not that of works dating from the Ch`in or Han
period. The Han Emperor Kuang Wu [25-57 A.D.] apparently quotes
from it in one of his proclamations; but the passage in question
may have been inserted later on, in order to prove the
genuineness of the work. We shall not be far out if we refer it
to the Northern Sung period [420-478 A.D.], or somewhat earlier.

6. LI WEI KUNG WEN TUI, in 3 sections. Written in the form
of a dialogue between T`ai Tsung and his great general Li Ching,
it is usually ascribed to the latter. Competent authorities
