Neil MacGregor's world history as told through objects at the British Museum. This week he is exploring high status objects from across the world around 700 years ago. Today he has chosen an astronomical instrument that could perform multiple tasks in the medieval age, from working out the time to preparing horoscopes. It is called an astrolabe and originates from Spain at a time when Christianity, Islam and Judaism coexisted and collaborated with relative ease - indeed this instrument carries symbols recognisable to all three religions. Neil considers who it was made for and how it was used. The astrolabe's curator, Silke Ackermann, describes the device and its markings, while the historian Sir John Elliott discusses the political and religious climate of 14th century Spain. Was it as tolerant as it seems?

This week Neil MacGregor, the director of the British Museum, has chosen some of the great status symbols of the world around 700 years ago - objects with quite surprising links across the globe.

Today he is with one of the most familiar objects at the museum; a board game, found in the Outer Hebrides but probably made in Norway - the Lewis Chessmen. They are carved out of ivory and many of the figures are hugely detailed and wonderfully expressive. They take us to the world of Northern Europe at a time when Norway ruled parts of Scotland and Neil describes the medieval world of the chessmen and explains how the game evolved. The historian Miri Rubin considers the genesis of the pieces and the novelist Martin Amis celebrates the metaphorical power of the game of chess.

This week Neil MacGregor has been looking at objects from Japan, Britain, Java and central Europe, exploring the great arcs of trade that connected Africa, Europe and Asia a thousand years ago. Today he sifts through a selection of broken pots, found on a beach in East Africa, to see what they might tell us. Smashed pottery, it seems, can be astonishingly durable and can offer powerful historical insights. These ceramic bits - in a variety of glazes and decorations - were found on the island of Kilwa Kisiwani off Tanzania. Neil uses the fragments to tell the story of a string of thriving communities along the East African coast with links across the Indian Ocean and beyond. The historian Bertram Mapunda and the writer Abdulrazak Gurnah describe the significance of these broken pieces and help piece together the great cross-cultural mix that produced the Swahili culture and language.

A history of the World in one hundred objects arrives on the Indonesian island of Java. This is the series that offers a new history of humanity through the individual objects that time has left behind. These items are all in the British Museum and the series is presented by the museum's director, Neil MacGregor. Throughout this week Neil is tracing the great arcs of trade linking Asia, Europe and Africa around a thousand years ago. Today he has chosen a stone head of the Buddha that comes from one of the world's greatest monuments, the giant Buddhist stupa of Borobudur. Borobudur rises from a volcanic plain in the middle of Java, built from one and a half million blocks of stone and devised as an architectural aid to spiritual practice. Neil MacGregor reports from the various levels of Borobudur and describes the trade routes that brought Buddhism to South East Asia. He also explores the impact the discovery of Borobodur had on the founder of Singapore, Sir Stamford Raffles and his ideas about the importance of Javanese civilization. The anthropologist Nigel Barley celebrates the life and work of Stamford Raffles while the writer and Buddhist teacher Stephen Batchelor sums up the spiritual significance of Borobudur

The history of humanity as told through one hundred objects from the British Museum in London. This week Neil MacGregor is looking at objects from Tanzania, Britain, Java and central Europe, exploring the great arcs of trade that connected Africa, Europe and Asia around a thousand years ago. Today he arrives in Japan with an object that offers a dramatic twist on the week's theme. This small mirror from the bottom of a sacred pond comes from a time when the Japanese suddenly cut themselves off from the outside world and stopped all official contact with China, a country it had frequently borrowed ideas from. Neil tells the story of the Heian period of Japanese history, a moment of great cultural awakening in Japan, especially in literature. The object is a small mirror that was found at the bottom of a sacred pond. The writer Ian Buruma and the archaeologist Harada Masayuki help describe the Japan of this time.

This week Neil MacGregor is exploring life in the great royal courts across the world during Europe's medieval period, from the heart of Europe to Mexico and Sri Lanka. Today he is in China of the Tang Dynasty around 700 AD. He tells how the elite of the time chose to leave their mark on the world by writing or commissioning their own obituaries. He is with a curious troupe of ceramic figures that were found in the tomb of a Tang general along with a stone tablet proclaiming his achievements. The China scholar Oliver Moore explains the growing ambitions of the dynasty and journalist Anthony Howard describes the enduring power of the obituary.

The history of the world as told through one hundred of the objects. The objects are selected from the collection of the British Museum by its director, Neil MacGregor.

This week, Neil is exploring life in the great royal courts across the world during Europe's medieval period. It's easy to forget that the civilisations of Tang China, the Islamic Empire and the Maya in Mesoamerica were all at their peak during this time and today we discover what was happening in South Asia during this period. He tells the story through a beautiful statue of the female Buddhist deity, Tara, crafted for a powerful ruler in Sri Lanka 1,200 years ago. Richard Gombrich explains what Tara means to Buddhism and the historian Nira Wickramasinghe describes the powerful interaction between Hinduism and Buddhism, India and Sri Lanka at this time.

This week, Neil MacGregor is exploring life in the great royal courts around the world during Europe's medieval period. It's easy to forget that the civilisations of Tang China, the Islamic Empire and the Maya in Mesoamerica were all at their peak during this time. He is describing the life of these courts through individual objects in the British Museum's collection. In the last programme he was with the Abbasid court North of Baghdad and an exotic wall painting; today's object is an engraved rock crystal connecting a biblical tale to a real life story of royal intrigue at the heart of Europe.

The Lothair Crystal was made in the mid-ninth century and offers scenes in miniature from the biblical story of Susanna, the wife of a rich merchant who is falsely accused of adultery. The crystal was intended to exemplify the proper functioning of justice but, intriguingly, the king for whom the piece was made was himself trying to have his marriage annulled so he could marry his mistress! The historian Rosamond McKitterick explains what we know of the court of King Lothair and former senior law lord, Lord Bingham, describes the role of justice as portrayed in this exquisite work of art.
