The theme was probably suggested by the humanist Poliziano. It depicts Venus born from the sea foam, blown by the west wind, Zephyr, and the nymph, Chloris, towards one of the Horai, who prepares to dress her with a flowered mantle. The seascape, stunning for its metaphysical tone and almost unreal quality, is illuminated by a very soft, delicate light. The real meaning of this dreamlike vision is still under scholarly debate and investigation but is undoubtedly linked with the Neo-Platonic philosophy, widely cultivated in the Medici court.", "license": " "attribution": "N/A", "sequences": [ { "@id": " "@type": "sc:sequence", "label": [ { "@value": "Normal Sequence", "@language": "en" } ], "canvases": [ { "@id": " "@type": "sc:canvas", "label": "The Birth of Venus", "height": 18840, "width": 30000, "images": [ { "@context": " "@id": " "@type": "oa:annotation", IIIF Manifest

22 IIIF and Semantic Indexing

23 Proposed Semantic Tagging Method

24 IIIF Limitations Representing polygons with Image API Presentation API design No immediate support for semantic tagging Current specification based on Open Annotation No strict adherence to Semantic Web standards and ontologies
