Some answers please to a couple of questions,please. Also any links will work also as I have just gotten into this site(couple months).
1. In this post and the previous one the sleds all have a curved end usually at the forward end, are these ends complete across the front on all sleds or just at sides with tie ins across the bottom of the sled? On this post (3rd pic) the sled has ropes attached to the sled at the rings(maybe-maybe not) and there is a ring at the other end. Could they have attached ropes to the rearward ring after they got the object(i.e. obelisks) to chosen site and after they set up the base for reception of object(dug a hole with a solid stone base??)(really don't know about the base point) they,as in the depiction, levered up the base and pulled up the object forward with a set of anchor ropes in the opposite direction, and could the design of the rounded end be to allow the easement of raising the object also could this allow the curved side pieces to slice into the sand going below ground level and letting the base of object slide slightly forward into the depression made earlier?(sorry about the long-winded question worried that I could not get the right picture across). Also I have seen where alot of people say they either drug the ramps across the sand or logs crushing them but in above pic.(#3) it looks to me like they are placing square stone slabs or cast bricks which could be mass produced.Could these be cut limestone such as those used as casing stones? I have herd they get harder the older the get from the heat . Couldn't the friction harden them also?
Last question honest, on the same pic(#3) do you know what is represented by the curved objects on the wagons at top right and if they had oxen as shown before in pics, why are humans pulling these carts? Were they too few in number? Oops I guess I lied about that last question thing! Anyway all info will be appreciated!!
