  1. ^ Sima Yan's biography in Book of Jin indicated that Sima Gui died on the gengchen day of the leap month of the 10th year of the Taishi era. The date corresponds to 12 March 274 on the Julian calendar.([泰始十年闰月]庚辰,太原王瑰薨。) Jin Shu, vol.03.
  2. ^ While historical sources did not indicate how old Sima Yong was when he inherited the title of Prince of Taiyuan, his father Gui's biography in Book of Jin noted that Gui died young. (...不幸早薨,...) Jin Shu, vol.37. Thus, Sima Yong was likely to be young when he became Prince of Taiyuan. Thus, his birth year should be c.early 260s.
  3. ^ not to be confused with his uncle who has a similar name when transliterated in English (司马邕).
  4. ^ Volume 86 of Zizhi Tongjian indicated that Sima Yong was killed between the renwu day and the xinchou day of the 12th month of the 1st year of the Guangxi era. The dates correspond to 20 Jan and 8 Feb 307 in the Julian calendar.
