《许衡集》是指元代重要的思想家、政治家和教育家许衡(1209—1281)的现存著述集。它是保存许衡著述的重要文献,是研究许衡学术和思想的基本依据。总结归纳《许衡集》主要版本之授受源流,可以发现《许衡集》主要呈现出三个版本系统,即以大德初刻本《鲁斋遗书》6卷为首的系统、以明正德十三年(1518)刻《鲁斋全书》7卷为首的系统和以明万历二十四年(1596)刻《鲁斋遗书》14卷为首的系统。三个版本系统联系紧密,但又各具特点。 “Xu Hengji” refers to the extant collection of Xu Heng (1209-1281), an important thinker, politician and educator in the Yuan Dynasty. It is an important document for the study of Xu Heng’s writings, and is the basic basis for the study of Xu Heng’s academic and ideological thoughts. Summarizing and summarizing the main source of “Xu Heng Ji”, we can find that “Xu Heng Ji” mainly presents three versions of the system, that is, Year (1518), a system headed by Volume 7 of the “Lu Zhai Book” and a system headed by 14 volumes of the “Lu Zhai Sishansu” inscribed in the Ming Wanli twenty-four years (1596). Three versions of the system are closely linked, but each has its own characteristics.
