5. Lieve Verschuier’s ‘Tail Star (Comet) over Rotterdam’
By Lavinia Gambini (https://cambridge.academia.edu/LaviniaGambini)
For early modern contemporaries, comets were not only associated with the birth of Christ. Comets possessed an eschatological dimension and had often been considered signs of imminent catastrophes, such as the Thirty Years’ War. The celestial phenomenon also retained its apocalyptic dimension in the ‘Scientific Revolution’, when in Cambridge the Lucasian Professor for Mathematics, William Whiston, announced in A New Theory of the Earth (1696) that the Earth would soon collide with a comet, finally initiating the Millennium of Christ’s rule.
However, the early modern period was also the age of wonder, an epistemic process of cognitive appropriation and response to marvellous natural phenomena. In Lieve Verschuier’s painting of the Great Comet of 1680 over Rotterdam, we see a crowd marvelling at the magnificent sight. Many spectators hold a Jacob’s staff (a tool used in navigation), probably to measure the length of the comet’s tail, while, in the lower right corner, a woman and a child turn away crying from fear. I like to think that these opposite reactions represent the artist’s incorporation of a contemporary scientific discourse about the legitimacy of fear of comets taking place in the Netherlands. Following the sighting, natural philosophers such as the Voetian circle, Christiaan Huygens, and Balthasar Bekker battled over the possibility of interpreting comets according to scripture and comets’ incorporation into the ‘Book of Nature’ – that is to say, whether comets were natural or supernatural. Still, they all agreed that comets were not ominous signs but a glorious expression of God’s majesty, that should not be feared but marvelled at. Verschuier’s painting thus does not only reflect this epistemic shift – with his figures bravely holding Jacob’s staffs towards the sky – but also proves that the early modern sciences cannot be thought about without religion.
