Back to João Rodrigues “Tçuzu”, the Jesuit who sent his readers “to the koyomi of Japan”. A nanban byōbu of around 1600 shows the people he lived among at Nagasaki: Jesuits in black cassocks, Japanese onlookers, the bustle of the Portuguese trade.

Prepping a talk for Beijing, I spent the morning with these—Japanese printed almanacs (koyomi) from the Bunsei years, 1819–21, from an Edo publisher. Every day gets its planet, its sexagenary name, its lucky and unlucky notes. A whole way of ordering time on one folded sheet.

I keep coming back to João Rodrigues, the Jesuit who wrote the first grammar of Japanese at Nagasaki (1604) and closed it with a treatise on Japanese time. When he needed the small calendar detail, he sent his reader “to the koyomi of Japan.” Sheets like these are what he meant.

🌎 ¿Exploración náutica o estrategia geopolítica global? En el siglo XVI, el piloto Juan Ladrillero conectó los «pasajes-mundo» de Panamá y el estrecho de Magallanes desentrañando los «secretos de la tierra» para el Imperio español. Ni azar cartográfico, ni simple navegación. 👇

Hac intellegentiae artificialis aetate, urgens fit humanam artem ab iis distinguere, quae machinis efficiuntur. Ars enim et ea, quae machina ex innumeris alienis imaginibus statisticae ope computationis generare potest, ontologice, prius etiam quam aesthetice, inter se differunt. Algorithmis humani deest favilla. Quapropter Ecclesia cum artificibus et humani cultus institutis foedus renovare cupit: foedus scilicet ad humanum custodiendum.

Un estudio de la Universidad Javeriana que concluye que “Airbnb llega donde ya era caro vivir [Medellín], no es que lo vuelva caro”, y que fue replicado en medios en pleno debate por la actualización del POT, fue pagado por Airbnb. Así se mueve el lobby de esa plataforma en la ciudad: 👇 elarmadillo.co/investigacion…

🐒 ¡La familia #UdeA tiene un nuevo integrante! Se trata de la primera cría de tití gris que nace en Ciudad Universitaria, Campus Medellín. 🤓 Este nacimiento ocurre dos años después de la llegada al campus de la hembra de tití gris, rescatada del tráfico ilegal. Su llegada y reproducción hacen parte de los procesos de conservación que adelanta la Alma Máter para esta especie, que se encuentra en peligro de extinción. 💚 Ya que #NuestraNaturalezaEsCuidarnos, la mejor manera de aportar al cuidado de la fauna que habita en este y los demás campus de la UdeA es no alimentarla y admirarla desde la distancia para evitar perturbarla. #UdeALaCasaDeTodos

In c. 1510, Andrés de Li's Reportorio de los tiempos explained the autumn equinox with a pair of scales: Libra, holding twelve ounces like the twelve months of the year. But for Li the Sun entered Libra on 14 September, not the 22nd. The calendar was drifting. #histsci #almanacs

Today is the equinox. For Andrés de Li it fell on 14 September, when the Sun entered Libra and made the days equal to the nights. A few days apart from ours, and a calendar reform still to come. #histsci #almanacs ⚖️

The Old English word for equinox is 'emniht', from 'efen' and 'niht', when night and day are evenly balanced. Today is the 'hærfestlice emniht', autumnal equinox; after this (says Byrhtferth of Ramsey) 'langað seo niht and wanað se dæg', 'the night lengthens and the day wanes'.
