O rex gencium & desideratus earum, lapisque angularis, qui facis vtraque unum, veni [et salva] hominem quem de limo formasti.
O Rex Gentium, whom all people desire
To honour and love with hearty affection,
The corner-stone that skilfully brought nigher [i.e. nearer]
The two testaments, making them one,
Old and new madest lawfully union,
Save, Lord, mankind, thy most noble creature,
Made of vile earth to resemble thy fair figure.
