52.1 · Funerals and Burial
mourning, lamentation beating the breast and lamenting as an expression of sorrow In a number of languages it is entirely impossible to use an expression such as ‘to beat the breast’ in referring to mourning or grief, since ‘to beat the breast’ is often employed as a gesture of self-congratulation or pride in accomplishment. In a number of instances the closest equivalent of ‘to beat the breast’ is ‘to beat the head’ or even ‘to pull out the hair.’
1 The meanings of κόπτομαι and κοπετός in Domain 52 differ from related meanings in Domain 23 Physiological Processes and States and Domain 25 Attitudes and Emotions, since the expressions of grief in LUK 8:52 and ACT 8:2 reflect a form of ritualized and institutionalized mourning.
