ramp

Beaver一家の場所は危ないと知ったLucy達は、魔女に騙されて出て行った次男のEdmundを除き、Beaverの家を出てTable Stoneに向かいます。途中でFather Chirismasに会いました。
"These are your presents," was the answer, "and they are tools, not toys. The time to use them is perhaps near at hand. Bear them well." With these words he handed to Peter a shield and a sword. The shield was the colour of silver and across it there ramped a red lion, as bright as a ripe strawberry at the moment when you pick it.
"ramp" の単語は高速道路の出入り口の道路、傾斜と、動詞の傾斜するしか思い浮かびません。ここの "ramped" はライオンの図柄の形容なので何だろうと考えて見ると、この手のライオンは立っている場合がありますが、その様な意味になるのでしょうか？　辞書で確認します。
・Oxford English Dictionary: [no object] archaic (of an animal) rear up on its hind legs in a threatening posture:
they roared and ramped in cages
・Dictionary,com:
(of animals) to stand or move with the forelegs or arms raised, as in animosity or excitement.
(of a lion or other large quadruped represented on a coat of arms) to rise or stand on the hind legs.
