1st Seal - the white horse and rider
The bow is symbolic of evil intentions. The horse's rider is the first of four riders who each mark the beginning of a sequence of awful times.
The man or the group the man represents has a bow which is an instrument of war and he is setting out as a conqueror bent on conquest also he is wearing a crown. Greek for crown is Stephanos which means a victor’s crown as against diadem which was a royal crown.
Notice who God gets to open this seal the Lamb of God.
White horses were used by victorious Roman Generals in parades called Triumphs. They were an emblem of triumph and power by Rome over a foreign enemy.
The 1st Seal the white horse
1 I watched as the Lamb opened the first of the seven seals.
Then I heard one of the four living creatures say in a voice like
thunder, "Come!" 2 I looked, and there before me was a
white horse! Its rider held a bow, and he was given a crown, and he rode
out as a conqueror bent on conquest.
