What Trojan is that same that looks so heavy?

Agamemnon
What Trojan is that same that looks so heavy?
Ulysses
The youngest son of Priam, a true knight,
Not yet mature, yet matchless firm of word,
Speaking in deeds, and deedless in his tongue,
Not soon provoked, nor being provoked soon calmed,
His heart and hand both open and both free.
For what he has, he gives; what thinks, he shows;
Yet gives he not till judgment guide his bounty,
Nor dignifies an impair thought with breath;
Manly as Hector, but more dangerous,
For Hector in his blaze of wrath subscribes
To tender objects, but he in heat of action
Is more vindicative than jealous love.
They call him Troilus, and on him erect
A second hope, as fairly built as Hector.
Thus says Aeneas, one that knows the youth
Even to his inches, and with private soul
Did in great Ilium thus translate him to me.
Alarum. The fight begins.
