This poem was written by mystic Mechthild of Madgeburg in the 13th century. 

O burning mountain,

O chosen sun,

O perfect moon,

O fathomless well,

O unattainable height,

O clearness beyond measure,

O wisdom without end,

O mercy without limit,

O strength beyond resistance,

O crown of all majesty,

the humblest you created sings your praise,
