 A different, unknown script, which appeared more similar to Chinese (incorporating many characters borrowed directly from Chinese), had been discovered on a temple monument in 1935, as well as on a memorial to Xiao Xiaozhong in 1951; and in 1962 Jin Guangping suggested that these two monuments were written using the Khitan large script, and that the "Record of the Younger Brother of the Emperor" and the imperial memorial tablets were written using the Khitan small script.This identification of the two Khitan scripts is now widely accepted.There are about 15 known monuments with inscriptions in the Khitan large script, ranging in date from 986 to 1176, and about 40 known monuments with inscriptions in the Khitan small script, ranging in date from 1053 to 1171.
