Reddish Blonde Girl In A Spa

The term is derived from the name the town Spa, Belgium, whose name is known back to Roman times, when the location was called Aquae Spadanae, perhaps related to the Latin word "spargere" meaning to scatter, sprinkle or moisten.
Since medieval times, illnesses caused by iron deficiency were treated by drinking chalybeate (iron-bearing) spring water (in 1326, the ironmaster Collin le Loup claimed a cure, when the spring was called Espa, a Walloon word for "fountain").
In 16th century England, the old Roman ideas medicinal bathing were revived at towns like Bath, and in 1571 William Slingsby who had been to the Belgian town (which he called Spaw) discovered a chalybeate spring in Yorkshire. He built an enclosed well at what became known as Harrogate, the first resort in England for drinking medicinal waters, then in 1596 Dr Timothy Bright called the resort The English Spaw, beginning the use the word Spa as a generic description.
