Our Lady of Mount Carmel is a name given to Holy Mary who is the Patron of the Carmelite Order (religious institution that was founded around 12th century on Mount Carmel in Israel). There are many artworks that are associated with Our Lady of Mount Carmel.
There is also something called the Scapular of Our Lady of Mount Carmel which is a garment (usually brown one) that goes around someone’s neck or waist (depending where you place it). The Scapular is usually used for devotional purposes. It is said that Holy Mary came to St. Simon Stock on July 16th, 1251, and she showed him the Scapular and said:
“Receive, my beloved son, this scapular of thy Order; it is the special sign of my favor, which I have obtained for thee and for thy children of Mount Carmel. He who dies clothed with this habit shall be preserved from eternal fire. It is the badge of salvation, a shield in time of danger, and a pledge of special peace and protection.”
From then, the Carmelites became an Order dedicated to the helping the poor and sick. Also, St. Simon Stock was elected the Superior-General of the Order in 1254. Additionally, there are typically two types of Scapulars: monastic and devotional, but there are also different types of other Scapulars that have been approved by Popes and are used for devotional purposes.
There are very beautiful paintings and statues done to honor Our Lady of Mount Carmel. I included one painting and two statues, though there are many more that are absolutely stunning. There are also some more statues on the wiki page.
