Over the impressionable Alexander I.

He was anxiously sensitive about the opinion of others, eager for their sympathy and regard, and, in general, impressionable to their influence.

A programme so stupendous awoke in Alexander's impressionable mind an ambition to which he had hitherto been a stranger.
