...Salomon de Bray’s skills at observation are evident as is the lighting which seems oddly fresh and vibrant for a Dutch painter. De Bray's artistic development is not well documented. In 1635 he seemed to favor half-length figures, which at that time had become rather old-fashioned. By about 1640, his work showed the influence of Rembrandt van Rijn's “chiaroscuro”. The term chiaroscuro refers to a strong, self-conscious juxtaposition of light and shade which results in a stunning visual effect in a work of art. The technique was initially pioneered by Leonardo da Vinci, further developed by Caravaggio, and finally perfected by Rembrandt.

Perhaps Salmacis from Ovid.
...But she would not pick up a javelin...
Instead she would bathe her beautiful limbs and tend to her hair,
with her waters as a mirror.
Ovid, Metamorphoses. Book IV, 306-312
