Andrea Pozzo e il Venerabile Collegio Inglese a Roma
This paper outlines the work of Andrea Pozzo for the Venerable English College in Rome. It explores the context of his work there facilitated by the Jesuit, Francesco Eschinardi, who was a member of the College staff

St Joseph, St Peter, Jean Gerson and the Guelphs
The representation of St Joseph in Renaissance art has attracted scholarly attention in recent years, but not that of St Peter. Considering his prevalence in late antique and medieval art, Peter's artistic representation in the early modern period is remarkably rare. This article finds that the two saints were inextricably linked, particularly after the period of councils in the first half of the fifteenth century. It examines the significance of their conflation through the writings of Jean Gerson at the Council of Constance when the role and nature of a single pope to replace the three of the Great Schism was being debated. Joseph, as protector of the Holy Family and of the infant Jesus, was paralleled with Peter who accompanied the adult Christ: Joseph's marriage to the Virgin Mary was a model for the metaphorical marriage of Christ to his Church which he delegated Peter to look after as his vicar. Therefore Joseph was a model for the successors of Peter – the popes – to follow. The imagery was particularly relevant in a Guelph context, which ensured its prevalence until the period of the Italian Wars
Weaving the Edinburgh Seven
In 2019 Scottish contemporary artist, Christine Borland, was commissioned to design work in collaboration with Dovecot Tapestry Studios in Edinburgh. The three tapestries go on show at the Victoria and Albert Museum in London on 8 March before their display at the Edinburgh Futures Institute in June 2024
Mitochondrial DNA Diversity and Population Structure of Spotted Seatrout (Cynoscion nebulosus) in Coastal Waters of the Southeastern United States
Restriction-site variation in mitochondrial (mt)DNA was examined among 470 spotted seatrout (Cynoscion nebulosus) sampled from eight localities in the northern Gulf of Mexico (Gulf) and two localities along the southeastern (Atlantic) coast of the United States. mtDNA fragment patterns generated 81 distinct mtDNA haplotypes (genotypes), three of which were found in 64% of the individuals assayed. Nucleotide sequence divergence among mtDNA haplotypes ranged from 0.148 to 1.808% and averaged (±SD) 0.676 ± 0.296%. Significant heterogeneity in mtDNA haplotype frequencies was detected between regions (i.e., Gulf vs Atlantic) and among sample localities from the northern Gulf. The latter appears to stem primarily (but not exclusively) from heterogeneity among samples from the western Gulf. Frequency plots of two of the common mtDNA haplotypes revealed strong east-west clines across the northern Gulf, with distinctive frequency discontinuities ( steps ) between Gulf and Atlantic samples and between the westernmost sample in the Gulf (the lower Laguna Madre in Texas) and the next-most geographically proximate sample to the east. Spatial autocorrelation analysis of mtDNA haplotype frequencies among samples from the northern Gulf revealed a strong isolation-by-distance effect. These results support the hypothesis that spotted seatrout are spatially subdivided into discrete subpopulations or stocks. Divergence between Gulf and Atlantic subpopulations is likely related to historical vicariance, stemming from climatic changes occurring during glacial times. Other factors likely reduce present-day gene flow between subpopulations in the two regions. Divergence among subpopulations in the northern Gulf is more likely due to behavioral factors that limit (female) dispersal from a natal bay or estuary. The latter is consistent with studies of life history and returns from mark-and-recapture experiments. mtDNA diversity, an index of evolutionary effective (female) population size, also differed significantly among samples, with spotted seatrout from the lower Laguna Madre possessing appreciably reduced mtDNA diversity. This indicates a reduction in the effective number of females in the lower Laguna Madre and suggests that careful monitoring of spotted seatrout in the estuary may be warranted
