Although astronomical guides were available in the early nineteenth century, they tended to come from continental presses and were rarely in English. This two-volume work by the clergyman and astronomer William Pearson (1767–1847) aimed, with brilliant success, to compile data from extant sources into one of the first English practical guides to astronomy. Most of the tables were updated and improved versions, and some were wholly reconstructed to streamline the calculation processes. Sir John Herschel dubbed it 'one of the most important and extensive works on that subject which has ever issued from the press', and for his efforts Pearson was awarded the gold medal of the Astronomical Society. First published in 1824, Volume 1 chiefly comprises extensive tables to facilitate the reduction of a range of astronomical observations, including solar and sidereal movements, alongside thorough instructions. In the history of science, Pearson's work reflects the contemporary challenges of celestial study.

William Pearson is a retired design engineer who for much of his life has been an amateur historian and archaeologist. Articles by him on these subjects have appeared in the journals of various societies in the north-east of England. He is a former Member of the Institute of Linguists and currently a member of the English Place-Name Society, the Cleveland and Teesside Local History Society and the Teesside Archaeological Society, having served as Chairman of the last. Decades ago, friendships were established with certain Danes in Stockton-on-Tees who were fellow employees of his company. This led to living abroad, including a period in Copenhagen. As a result of a growing awareness of the wider culture of Scandinavia, interest was aroused in the effects that the Viking interventions had on Britain.Erik Bloodaxe and Egil Skallagrimsson came to the fore, both for their narrative possibilities and examples of how events of the Viking period have come to be distorted and misunderstood. The eventual result is this book. The life of Erik begins with his background and career in Norway followed by his overseas adventures. After seizing power in northern England he met a violent death there. Also covered is much of the life of the Icelander Egil Skallagrimsson, who tried his best to be a thorn in the side of Erik and his wife Gunnhild. After Erik fell his kin fought desperately to maintain eminence. The western Viking movement was due to revive in a more organised form, but after sporadic outbursts of warfare eventually subsided to emerge as modern nations whose folk were still to be culturally productive like their Viking forebears, but without their collective tendency to violence.To obtain a complete account the sources were ransacked. Certain anomalies showed up involving the identities of some of the characters and the places where events are said to or are believed to have taken place. Attention was directed to solving these problems. Discrepancies in the relationship between three English kings in the mid tenth century and Scandinavians are particularly serious, but can be resolved with certain adjustments. For instance, students of these times have long disputed the location of the important Battle of Brunanburh. Yet another site is proposed, this being not so very far from York.Cover design is by Luke Pearson, the author's grandson and a prolific graphic artist. It is based on suggestions provided by the author. Apart from comic books, such as the popular "Hilda and the ...." series, his work has now been extended into the realm of animated film.
