Taboos vs prohibitions - see geas(a), aka surreal obligations/prohibitions
In the Irish cycles, a character will be forewarned by a religious figure (usually as a nipper) regarding prohibitions specific to the individual in question. They range from not staying in a guesthouse beyond 9 days, to not riding behind 3 red riders, to even more seemingly ludicrous plots
They work as social norms and frequently incur a triple death, compounded by characters doing everything they can to avoid their own geasa but, in turn, transgressing enough to enable their own end. See Diarmait mac Cerbaill and Bec mac Dé, Celchtar etc, or even Myrddin in Wales
Different in meaning to the Anglo-Saxon concept of the wyrd, which is a wayward turn but there’s a degree of overlap too regarding The Fates. If you look at bog bodies they’re nearly always placed along boundary settlement thresholds, whether in Ireland or Denmark. Ritualistically tortured but questions relate to status - volunteer or criminal? No-one really knows officially although slicing off nipples suggests the latter, eg suckling a king’s nipple was a sign of a subject’s sublimation
See Freud about sublimation, to invigorate art, sociality/civility and “progress”
