Visually translate the scene from Exodus 15:20-21 into a stained-glass masterpiece respectful to Christianity. Picture Miriam, identified as a Middle Eastern woman wearing traditional biblical attire, with a timbrel in her hand, leading a group of diverse women - including South Asian, Black, Caucasian, Hispanic, all in similar attire. They follow her in a dance, their movements fluent and full of joy. Each lady also carries a timbrel. Refrain from adding any text or words in the composition. Incorporate symbolic visual elements suggesting the triumph of the Lord, such as the representation of a horse and its rider emerging from the sea.
