There are 2 hymns I know of that pay respects to her:
''I sing of golden-throned Hera whom Rhea bare. Queen of the Immortals is she, surpassing all in beauty : she is the sister and wife of loud-thundering Zeus,--the glorious one whom all the blessed throughout high Olympos reverence and honour even as Zeus who delights in thunder''
''O royal Hera, of majestic mien, aerial-formed, divine, Zeus' blessed queen, throned in the bosom of cerulean air, the race of mortals is thy constant care. The cooling gales they power alone inspires, which nourish life, which every life desires. Mother of showers and winds, from thee alone, producing all things, mortal life is known : all natures share thy temperament divine, and universal sway alone is thine, with sounding blasts of wind, the swelling sea and rolling rivers roar when shook by thee. Come, blessed Goddess, famed almighty queen, with aspect kind, rejoicing and serene.''
They are found in temples and texts that describe followers singing them as they made offerings in her temples
