Two months after the end of the project, the members of the RUTTER team reflect on what working on the project – and on an @ERC_Research project – has meant to them, both personally and professionally. Find their stories here: https://t.co/KrECCreADz

Such a necessary book to clarify actual historical questions concerning #longitude—a topic that has been misleadingly presented as an English question, when in fact it has a long history and considerable developments with navigation in Early Modern Portugal. #Histsci

Tomorrow, at 19:00, Brotéria, Lisbon. Free participation! In collaboration with the Institute for Advanced Jesuit Studies. @IAJSBC @ciuhct @ERC_Research

New book! #Rutters and logbooks were more than navigation aids: they shaped #cartography, law, science and Europe’s global expansion. Essential reading on how #oceans connected the #EarlyModern world. Available at: https://t.co/wlAlXlAn0t #MaritimeHistory #GlobalHistory #histsci

Over the past six years, the RUTTER team published a total of 128 posts in the Reading Rutters blog, plus 59 in its sister Arabic Science and Philosophy blog. @aceved0villalba sums up this activity in the post https://t.co/4Hu3WdhYpL @ERC_Research @ciuhct

Henrique Leitão closing remarks: "The RUTTER project officially ended on 31 August 2025. It will take some time for RUTTER's contributions to percolate in the academic world, but their impact will be felt. It was a unique privilege to lead such an exceptional group of people."

Is it dangerous to mistake one fish for another? Yes, especially if your intention is to eat them. Read the post "Fish-Tasting and Toxic Navigation: Life and Death at Sea in 1526" by Luana Giurgevich about the case of poisoning onboard the ship Conceição. https://t.co/gZR8LNpEt9

In early modern #navigation, theory met practice at #sea. Cosmographers had the models, but #pilots had the skills—and they almost always won. Read the finale of Pilots Always Win by @JMMorenoMadrid at https://t.co/jIv2qIphPO @ciuhct @ERC_Research

“The chain of authorities is not hearsay and not mere bibliography, it is as if we ourselves had seen the fever abate under the crocodile's fang, and memories return under the hoopoe’s tongue”—a new post! https://t.co/F1ijCqEwP7 @ERC_Research @ErcRutter @ciuhct #histsci #philsci

You know an #internship on #rutters was a success when the intern, after finishing the activity, asks to see original #manuscripts! Thank you, Biblioteca de #Ajuda, for welcoming Francisco under the guidance of Luana Giurgevich. #CienciaVivaNoLaboratorio @ERC_Research @ciuhct

Pilots and cosmographers clashed over truth and accuracy: while cosmographers sought geographic precision, pilots saw #charts as practical tools for #navigation—not reflections of the Earth’s true form. Read more in the blogpost by @JMMorenoMadrid. https://t.co/MuMQXdqK8T #maps
