Coign of vantage

...it seemed as if the traders had occupied with nests, bearing the same proportion to the building, every buttress and coign of vantage, as the martlet in Macbeth’s Castle.

...a spacious gallery, from which latter coign of vantage an excellent view of the stage is afforded

The enclosure was encircled by a dense and perfect sea of faces. Every coign of vantage had been monopolised, windows and house tops not excepted

…the task of utilising the Duma rostrum and turning all the semi-legal and legal organisations of the working class into coigns of vantage.

That feeling of being alone, in a strange place, and of being silently looked at, inspected, taken stock of, from some coign of vantage of which one knows nothing, is one of the most trying experiences, one of the most severe nerve-tests, which a human being can go through.
