What did Edmund Burke mean by stating that after the French revolution, "the glory of Europe" was extinguished forever?

I believe he was lamenting the death of Marie Antoinette.

Here is some insight into th man and the quote in question:

Edmund Burke (1729-1797), born in Dublin, Ireland, was a member of the British House of Commons. After the French Revolution, Burke became an important critic of the Revolution and the effective founder of modern conservative political ideology. Although he had serious reasons for his politics, there is also an element of nostalgia about in his perspectives.

In this brief speech he laments the death of the Queen and the passing of an era.

"But the age of chivalry is gone; that of sophisters, economists, and calculators has succeeded, and the glory of Europe is extinguished forever.

Never, never more, shall we behold that generous loyalty to rank and sex, that proud submission, that dignified obedience, that subordination of the heart, which kept alive, even in servitude itself, the spirit of an exalted freedom!

The unbought grace of life, the cheap defense of nations, the nurse of manly sentiment and heroic enterprise is gone. "

Although Burke had supported the American War for Independence, which he saw as an appropriate response to the situation regarding the American colonists, he condemned the French Revolution in his Reflections on the Revolution in France in November 1790.[6] With it, Burke became one of the earliest and fiercest critics in Britain of the French Revolution. He saw it, not as movement towards a representative, constitutional democracy, but rather as a violent rebellion against tradition and proper authority and as an experiment disconnected from the complex realities of human society. Burke argued that the new doctrines of France were simple and abstract, that since they did not recognize the nature and orders of people, it could never replace the present ones. As such, he predicted, it would end in disaster.
