                                            "Generate an image of Diarmait Mac Murchada, the High King of Ireland, in a realistic medieval style. Depict him as a regal, authoritative figure in his mid-40s, wearing a crown and ornate Celtic-inspired attire, with a backdrop of the Irish landscape, possibly with a subtle hint of the Norman invasion in the distance. Incorporate elements that reflect his role as a king, such as a scepter or a sword, and consider including symbols of his alliances with the Normans, like a subtle nod to the presence of Richard de Clare or Robert FitzStephen."
