It might be worth mentioning the problems associated with the Left -Right binary oppositions happily used by the Scandinavian and some UK proponents of the Sun Horse theory .
The main one is that allows everything that might be said to have an orientation and having a prow / head etc to become part of the theory regardless of what direction it might be facing , or taking into account the all important contextual factors like slope of rocks /hills , contours and natural features like cracks and fissures that are likely to influence the orientation of figures . Another is that it allows any figure that would otherwise be considered to be facing in the “wrong “direction to become acceptable . e.g. when an observer is looking from the north towards a ship with a prow to the right , it might be assumed to be a “ Day“ship , just like the Trundholm chariot taking the sun from West to East , but that only works when looking at the ship from the North .When a ship with a prow to the right but looked at from the south it would then be a “Night “ ship taking the sun through the underworld in West -East direction . This is fine for observers looking at features that are facing East or West but the problems start when the figures are a long way from facing East or West as is the case with the Uffington horse .
All directions become compartmentalised into a very simplified convenient Left or Right binary choice providing more fuel for the theory , when the reality is that many ,including Uffington ,clearly don't belong .
