Rare first edition of Horrebow's textbook on astronomy. “(Horrebow) was a personal assistant to Ole Römer for four years. In 1714 he was made professor at the university and director of the observatory he held this position for fifty years, although two of his sons had to take care of his professional duties during his last years. He was a member of the academies of Copenhagen, Berlin, and Paris. Horrebow’s scientific life was shaped by two major influences. The first was his daily association during his youth with Römer, of whom Horrebow later spoke with the greatest devotion. Second, in the great fire in Copenhagen in 1728 nearly all of Römer’s papers and unpublished observations were destroyed together with Horrebow’s own observations" and from that time on it remained a matter of personal honor for Horrebow to describe fully Röer’s scientific achievements in order to preserve them for posterity. Throughout his lifetime Horrebow was a fertile author. He wrote several textbooks on astronomy, mathematics, and navigation which had a considerable influence at the university and at Danish schools.""

Rare first edition of Horrebow’s textbook on natural philosophy with a focus on astronomy. When young Horrebow had intensively studied Casper Bartholin’s work “Specimen philosophiae naturalis” and wanted to revise and possibly expand it:“When during the period 1747-53 the ageing professor of astronomy, Peder Horrebow, held the chair of physics, too, he felt the need for revising the praiseworthy ‘Specimen’, the 56 years old, from which he had himself in his youth acquired his knowledge of natural philosophy. And after having in vain tried to comment upon the ‘specimen’ and to change its text as well as its ordering of subjects he finally produced a completely new text-book [The present].” (Dobrzycki, The Reception of Copernicus’ Heliocentric Theory).
