An artistic representation of Genesis 25:1. Depict the scene with the mood and tone of a renaissance painting, crafting each element meticulously to be respectful and devotional to Christianity. The composition should avoid the use of text or words and focus purely on visual storytelling. In this scene, Abraham should be marrying Keturah, with viewers witnessing the holy sanctity of their union. The ambiance should emanate spirituality, piety, and solemnness prevalent in Renaissance-era Christian religious arts. Attention should be given to clothing, architecture and facial expressions to transport viewers to that era.
