{"product_id":"al-biruni-measuring-the-world","title":"Al-Biruni - Measuring the World","description":"\u003cp\u003eThis artwork shows al-Biruni surrounded by instruments. A globe, geometric diagrams, celestial markings. The visual language of a man who measured the world with extraordinary precision.\u003c\/p\u003e\u003cp\u003eAl-Biruni calculated the radius of the earth in the early eleventh century using a method of his own devising, working from a single mountain and the angle of the horizon. His result was within one percent of the modern figure. He wrote on astronomy, geography, pharmacology, mineralogy, history, and comparative religion, producing over one hundred and forty known works. He studied Sanskrit to read Indian scientific texts in the original. He described the rotation of the earth four centuries before it became accepted in Europe.\u003c\/p\u003e\u003cp\u003eHe was rigorous, curious, and systematically accurate in ways that made his contemporaries uncomfortable and his successors dependent on him.\u003c\/p\u003e\u003cp\u003eEvery artwork in the Riwayah collection is available in four premium display formats, crafted to suit every home and interior style. Our canvas prints offer a rich, textured finish that brings depth and character to each piece, stretched on FSC-certified wooden bars for a refined gallery feel. For a minimalist and versatile look, our magnetic hangers use durable pine wood to hold your print securely without marking it, making it easy to change artwork whenever you like. Those seeking a classic, museum-style presentation can choose our premium wooden frames, crafted from responsibly sourced oak or ash with visible natural grain and protected with shatterproof plexiglass. And for a sleek, contemporary finish, our aluminium frames pair clean black metal with heavyweight matte paper for a polished, modern aesthetic. All prints use FSC-certified paper and high-quality inks, arrive ready to hang or assemble, and are produced on demand in the UK to reduce waste and ensure the highest standard of craftsmanship.\u003c\/p\u003e","brand":"Project Riwayah","offers":[{"title":"Framed Canvas \/ Black frame \/ 30x40 cm \/
