Sherburn’s Sphere is a majestic rendering of the first book of the Astronomica, a celestial journey that lays the ground for understanding the celestial framework of astrology. It starts by explaining the construction, division and revolution of the sky (essential knowledge for an ancient astrologer, since drawing up an astrological ‘chart’ requires knowledge of what is being charted). It introduces and places the constellations, defines the celestial circles, explains how to find, monitor and measure the stars and planets, and offers a poet’s tour of awesome phenomena such as the Milky Way and the ominous lights of comets and fiery meteors.
Sherburne’s Sphere is accompanied by Mireille Crossley’s biographical account of the poet Manilius, with a focused, digestible timeline for his work’s rediscovery, transmission and reproduction. This pieces together a feasible biography with plausible details, allowing – for the first time – the figure of Manilius to emerge as a relatable, full-bodied character.
