Keble wrote a number of hymns and these are probably how he is likely to be known by the average Anglican. The following translation of Phos hilaron, made from the Greek in 1834, gives a taste of his talent as a hymnographer.
Hail, Gladdening Light
Hail, gladdening Light, of His pure glory poured,
Who is immortal Father; heavenly blest;
Highest and holiest--Jesus Christ our Lord!
Now are we come to the sun's hour of rest;
All times are ordered in Thy Word alone,
Therefore the day and night Thy glories own.
The lights of evening now around us shine;
We hymn Thy blest humanity divine;
Worthiest art Thou at all times to be sung,
By grateful hearts, with undefiled toungue,
Son of our God, Giver of life, alone!
Therefore shall all the worlds Thy glories own.
