Another one of the most famous one, Adoro te devote, written by Thomas Aquinas, also from the 13th century:
English translation:
I devoutly adore you, o hidden God,
Truly hidden beneath these appearances.
My whole heart submits to You,
And in contemplating You, it surrenders itself completely.
Sight, touch, taste are all deceived in their judgment of you,
But hearing suffices firmly to believe.
I believe all that the Son of God has spoken;
There is nothing truer than this word of Truth.
On the cross only the divinity was hidden,
But here the humanity is also hidden.
Yet believing and confessing both,
I ask for what the penitent thief asked.
I do not see the Holy Wounds as Thomas did,
But I confess that You are my God.
Make me believe much more in You,
Hope in you, and love You.
O memorial of our Lord's death,
Living Bread that gives life to man,
Grant my soul to live on You,
And always to savor your sweetness.
Lord Jesus, Good Pelican,
wash my filthiness and clean me with Your Blood,
One drop of which can free
the entire world of all its sins.
Jesus, whom now I see hidden,
I ask You to fulfill what I so desire:
That the sight of Your Face being unveiled
I may have the happiness of seeing Your glory. Amen.
