Plutarch Pericles 21

[1] But Pericles was ever trying to restrain this extravagance of theirs, to lop off their expansive meddlesomeness, and to divert the greatest part of their forces to the guarding and securing of what they had already won. He considered it a great achievement to hold the Lacedaemonians in check, and set himself in opposition to these in every way, as he showed, above all other things, by what he did in the Sacred War. ¹

[2] The Lacedaemonians made an expedition to Delphi while the Phocians had possession of the sanctuary there, and restored it to the Delphians; but no sooner had the Lacedaemonians departed than Pericles made a counter expedition and reinstated the Phocians. And whereas the Lacedaemonians had had the promanteia, or right of consulting the oracle in behalf of others also, which the Delphians had bestowed upon them, carved upon the forehead of the bronze wolf in the sanctuary, he secured from the Phocians this high privilege for the Athenians, and had it chiselled along the right side of the same wolf.
