The latin part uses text of Chritian scaldic poem, in honour of the Virgin Mary, by Anonymous author from 12th cenury:
Tua sun ubera
vino redolentia,
candor superat lac et lilia,
odor flores vincit et balsama.
(In english:
Your breasts are as fragrant as vine,
their whiteness whiter than milk and lilies,
their scent lovelier than flowers and balsam wood.)
