A few points: No one else did around that area.
counter to the point:
Faramir had just been healed by
Aragorn (hands of a king)
counter to the counter:
Merry was also healed and had no such recognition.
Counter to the counter to the counter: Merry was not exactly Aragorn's subject.
Counter to the counter etc: Really weak excuse.
1.
Numenorean's possessed foresite from offlate,
The Quote given below is about Aragon but Faramir was a guy of Hifh Numenorean
race too.
...suddenly the foresight of his kindred came to him,...
Appendix A
2. Yes, Hands of the King are the hands of the healer. That was an old proverb and Faramir was a wise and learned person, deep in the lore of
Gondor and must have heard this phrase. Once he got some recogniaztion of what was going on, he would have gathered in a instance Aragon's role and what that role made him: No big deal. Also remember the dream he had, about the
sword being reforged and
Imladris, for which
Boromir travelled North, he was a wise man and it is plausible that he had gathered something with accompanied by his foresite inherited from his ancestors he used to recognise Aragon as the king.
3.
Pippin had never heard this proverb before. And Pippin knew Aragon much more intimately, as
Strider, so much so that he had failed to grasp the real significance of Aragon's role. Pippin didn't see Aragon as the Head of
Rangers or even as the King [Till that point, although Some majesty was revealed at Angorath] but as Strider, who tricks and healing powers he knew from experience.
But to Faramir and the people of
Minas Tirith who weren't his chums and didn't knew him on a more intimate scale, he seemed like a King with all his hidden glory revealed and his Kingship approved once he proved himself to be a skillful healer.
At that time Faramir wasn't Aragon's subject either. If I recall correctly, till that time Aragon hadn't yet displayed the will of taking over the Kingship explictly, but Faramir perhaps felt himself to be Aragon's subject due to the physological effect of Aragon's revealed lineage and its implications.
4. Which one is a really weak excuse? About Merry being not his subject? No it is, as you see, Merry and people of Gondor saw Aragon from different prespective, Merry knew and loved the Strider side of Aragon, while to
Gondorians, from the start the Aragon, King Ellesar Telcontar side was revealed, so they were only acquinted with this side. This is like the same what people of Gondor precieved of
Hobbits. Due to their strangeness, their shining gares and the company they kept, they were precieved as fierce princes and I am sure
Bilbo would have laughed heartily if he had heard these rumors for to him they were but nice, gentlehobbits although a bit Adventrous.
