Death. Facial applellates also connect him with the 'chariot' [eer]. A pacifist? Certainly a man of peace [eternal].
He is facing left, the past? [ Why? Left is west, setting sun, land of the dead, autumn, harvest, the end - the future?].
A man of peace who has to go to war. It's not that unusual - remember Sassoon and Owen? That gentle face dressed up in these fierce war accoutrements.
The past is his family he left behind? His Lady whom he desires to honour in battle, before honouring in bed? The past is his future, he hopes. He faces the setting sun because that is where he comes from, if he he is a crusading knight. The land of the dead, because in war, all knights must face the dead sooner or later. Some come through, some don't. The moon on his shoulder- a reminder of the strange light of battle? or of Justice?
But none of this does he stop and think about - before and after the battle he'll have time to think. For now: he charges. But it is a charge that was prepared for a long time, that advances on strong foundations. In the Middle Ages, before battle, soldiers attended Mass and were shriven, in case they died. And no knight would have gone into battle without long and arduous physical, mental and spiritual training, which started when he was a child.
So the knight in a reading? not having time to think, just acting. But also - having to face the consequences of action, sooner or later. And - acting after a period of strict preparation: at last the day has come! It reminds me of those marathon runners who train, physically and mentally, for a long time, and finally the day comes and they must just forget all and run and run. Battles can last a long time - think of the charge of adrenalin. That could also be a sense of the reading.
And also - if he is a crusader, he fights for what he thinks is right, even if he does not like war. So a meaning could be: sacrificing our comfort and peace to pursue actively something we believe in.
If the Chariot is remembered, then we have the sense of show again, so this could be a knight in a tournament, showing off in front of his Lady (dangerous games, though- Henry II of France was killed in a tournament). Or the man in the Chariot has finally got a horse moving! (actually and not only spiritually).
