De Agri Cultura (] , "On Farming" or "On Agriculture"), written by Cato the Elder, is the oldest surviving work of Latin prose.
 Alexander Hugh McDonald, in his article for the "Oxford Classical Dictionary", dated this essay's composition to about 160 BC and noted that "for all of its lack of form, its details of old custom and superstition, and its archaic tone, it was an up-to-date directed from his own knowledge and experience to the new capitalistic farming."
 Cato was revered by many later authors for his practical attitudes, his natural stoicism and his tight, lucid prose.
 He is much quoted by Pliny the Elder, for example, in his "Naturalis Historia".

 He was a younger brother of Lady He, who married Sun He, a son and former heir apparent of the first Wu emperor Sun Quan.
 In 264, Sun He and Lady He's son, Sun Hao, ascended the throne as the fourth and last emperor of Wu.
 He Zhi, as a maternal uncle of the reigning emperor, rose to a more prominent position in the Wu government.
 In 279, Sun Hao appointed He Zhi as Minister over the Masses when Guo Ma (郭馬) started a rebellion in Wu, and ordered his maternal uncle and others to lead troops to suppress the revolt.
 In the following year, the Jin dynasty conquered Wu, after which Sun Hao surrendered.
 It is not known what happened to He Zhi after the fall of Wu.
Avunculicide is the act of killing an uncle.
 The word can also refer to someone who commits such an act.
 The term is derived from the Latin words "avunculus" meaning "maternal uncle" and "caedere" meaning "to cut or kill".
 Edmunds suggests that in mythology avunculicide is a substitute for parricide.
 The killing of a nephew is a nepoticide.
In discussing consanguineal kinship in anthropology, a parallel cousin or ortho-cousin is a cousin from a parent's same-sex sibling, while a cross cousin is from a parent's opposite-sex sibling.
 So a parallel cousin is the child of the father's brother (paternal uncle's child) or of the mother's sister (maternal aunt's child), while a cross cousin is the child of the mother's brother (maternal uncle's child) or of the father's sister (paternal aunt's child).
 Where there are unilineal descent groups in a society (i.e. matrilineal and/or patrilineal), one's parallel cousins on one or both sides will belong to one's own descent group, while cross cousins will not (assuming descent group exogamy).
