[How was Hadrian's Wall perceived in Rome]

What do people think about the reception of Hadrian's Wall at home in Rome itself?

 

I have read in some places that the senate were not fond of the Wall but was wondering if anyone knew any more in this?

 

Also whether the people, army and other elites were in favour or against the emperor's frontier?

[The Antonine Wall]

I just wondered what peoples' opinions and theories were on the reasons behind Antoninus Pius' decision to build his Wall in Scotland.

 

Do people think it was a mostly political choice or based more on strategy and a military decision?

 

Also what do people think are behind the reasons for its abandonment only 20 years (or so) later?
