Global tree-ring response and inferred climate variation following the mid-thirteenth century Samalas eruption

The largest explosive volcanic eruption of the Common Era in terms of estimated sulphur yield to the stratosphere was identified in glaciochemical records 40 years ago, and dates to the mid-thirteenth century. Despite eventual attribution to the Samalas (Rinjani) volcano in Indonesia, the eruption date remains uncertain, and the climate response only partially understood. Seeking a more global perspective on summer surface temperature and hydroclimate change following the eruption, we present an analysis of 249 tree-ring chronologies spanning the thirteenth century and representing all continents except Antarctica. Of the 170 predominantly temperature sensitive high-frequency chronologies, the earliest hints of boreal summer cooling are the growth depressions found at sites in the western US and Canada in 1257 CE. If this response is a result of Samalas, it would be consistent with an eruption window of circa May–July 1257 CE. More widespread summer cooling across the mid-latitudes of North America and Eurasia is pronounced in 1258, while records from Scandinavia and Siberia reveal peak cooling in 1259. In contrast to the marked post-Samalas temperature response at high-elevation sites in the Northern Hemisphere, no strong hydroclimatic anomalies emerge from the 79 precipitation-sensitive chronologies. Although our findings remain spatially biased towards the western US and central Europe, and growth-climate response patterns are not always dominated by a single meteorological factor, this study offers a global proxy framework for the evaluation of paleoclimate model simulations.

Abruptly Dogen

In the thirteenth century Dogen brought Zen to Japan. His tradition flourishes there still today and now has taken root across the world. Abruptly Dogen presents some of his pith writings—startling, shifting, funny, spilling out in every direction. They come from all seventy-five chapters of his masterwork, the Eye of Real Dharma (Shōbōgenzō 正法眼藏), and roam through mountains, magic, everyday life, meditation, the nature of mind, and how the Buddha is always speaking from inside our heads. An excerpt from chapter 1, “A Case of Here We Are”: Human wisdom is like a moon roosting in water. No stain on the moon, nor does the water rip. However wide and grand the light, it still finds lodging in a puddle. The full moon, the spilling sky, all roosting in a single dewdrop on a single blade of grass. A man of wisdom is uncut, the way a moon doesn’t pierce water. Wisdom in a man is unobstructed, the way the sky’s full moon is unobstructed in a dewdrop. No doubt about it, the drop’s as deep as the moon is high. How long does this go on? How deep is the water, how high the moon?

Saleroom Fiction versus Provenance

This article examines a group of twelve fragments in different languages and different scripts previously held in the Schøyen collection in London and Oslo. After they first emerged on the market in 1993, these fragments received colourful hypothetical and/or fictional pseudo-provenances. However, a consideration of the material logic of these parchment fragments (including folding lines and sewing holes) as well as an examination of the Arabic marginal manuscript notes they carry allows us to re-establish their historical trajectory from the seventh/thirteenth century onwards. At this point, they became part of Muslim Damascene manuscript culture and were reused as wrappers for small booklets in the scholarly field of ḥadīth. In the late ninth/fifteenth century, these booklets were subjected to a massive binding project and the fragments went into new large volumes. This article thus suggests approaches to use provenance research in order to re-historicize decontextualized fragments in modern collections.

Hanging Matters: Petty Theft, Sentence of Death, and a Lost Statute of Edward I

This article discusses an important aspect of the law relating to theft in thirteenth-century England, and one of the ways in which that law developed. Central to it is the argument that the treatise The Mirror of Justices and references in court records and reports show that a short statute enacted early in the reign of Edward I, probably in 1278, categorically defined 12d. as the amount, whether in goods or money, at which larceny became a capital felony, incurring judgment of death. As well as setting out the evidence for this hitherto overlooked ordinance, the article also argues that the statute can be associated with some significant developments in the way petty theft was treated subsequently. In particular it had the effect of promoting the development of penal imprisonment, while since the task of valuation was given to trial juries, it further enhanced the leading role of the latter in determining the fates of the men and women whose lives depended on their verdicts.

Attributing Another Song to Maroie de Diergnau de Lille

Maroie de Diergnau is a recognized thirteenth-century woman trouvère to whom one song has been attributed. This article argues that another Old French lyric, Jherusalem grant damage (RS 191, L 265–939), found in the Chansonnier du roi (Paris, Bibliothèque nationale de France, fr. 844, known as trouvère chansonnier M) should also be attributed to the songstress.
