In this essay, the children’s picture book Hilma af Klint: maps of invisibility by Ylva Hillström and Karin Eklund is analyzed with the aim of exploring the picture book as a medium and tool for art history writing. The analysis examines how the artist Hilma af Klint is portrayed and how art history is presented, as well as placing a particular focus on analyzing the interaction between image and text. The content is examined with semiotic image analysis, an inductive literature study as well as reception aesthetics analysis. The analysis concludes that Hilma af Klint as an artist is portrayed as fearless, curious and serious, and her artistic ambition is described as the desire to understand the universe. The design of the picture book and the ability to freely place and combine images and texts in different ways means that it is possible to convey the history of the art in several ways. With the picture book, sometimes several parallel stories are told; sometimes picture and text work together to complement each other, other tims the same thing is presented in both text and picture, or the pictures tell a story of their own or provide additional information that does not appear in the text. Depending on the experience of the viewer/reader, it is possible to derive different things from the picture book, and gaps can be filled as well as be left empty, which creates excitement and curiosity about the rest of the art world. Through the illustrations representation of af Klint's work and Eklund's way of illustrating the works the images in the book relate back to the children's/viewer's own world. The design of the picture book functions as a gateway to what it is like to look at art and art books and it works to create images within the viewer.

The coastline along Högklint and Gråberget, Gotland, Sweden, was examined in order to establish therate of cliff erosion, erosion patterns, as well as some of the driving factors of the erosional processes in the area. Picture comparisons of the coastline reveal some major geomorphological changes in the area over the last 100 years, and the coast is still changing. At present, gardens are slowly disappearing over the cliff edge, and during storms Buske fishing place is threatened to be destroyed.Cliff retreat values could be obtained on two locations with the help of a Light Detection and Ranging (LiDAR) system. Scans were made with the LiDAR in January and May 2013. The scans were latercompared in CloudCompare and a mean erosion rate of 0.159 m/a was obtained for the Högklint siteand 0.123 m/a for the Gråberget site. The cliffs were also studied with a Schmidt hammer that clearly showed how that the cliff face was more eroded below the visible groundwater table than above it. With Gemini Tinytag data loggers temperatures were measured from October 2012 to May 2013 at the surface of the cliff face and inside the cliff at a depth of 4.5 cm and 9.5 cm. It could be concluded that tempera- tures were within the frost-cracking window (-10 to -3 ºC) for 19.7 Julian days, not consecutive. Due to the visibly high water content in the cliff and temperatures within the frost-cracking window, ice segre- gation within the cliff is a possible eroding factor in the area.The cliffs are subjected to erosion caused by ground-, melt-, and rainwater in a significant degree, possibly even more so than by the impact of breaking waves. It is important that the municipality ofGotland takes action to prevent further damage on personal property and to prevent personal injury. Todo this further studies needs to be done on how future climate change will effect the coast and rate oferosion. / Kuststräckan längs med Högklint och Gråberget, Gotland, Sverige, undersöktes för att etablera erosionshastighet,erosionsmönster och de drivande erosionsprocesserna i området. Genom återfotografering ochbildjämförelse av kuststräckan konstateras stora geomorfologiska förändringar de senaste 100 åren.Kustförändringarna är en pågående process. I dagsläget försvinner trädgårdar bit för bit över klintkantenoch vid varje storm hotas Buske fiskeläge att förstöras.Med en Light Detection and Ranging (LiDAR) radar erhölls data över hur mycket som försvunnitfrån klinten på två platser längs området. LiDAR- skanningarna gjordes i januari och maj 2013. Mätningarnajämfördes sedan i CloudCompare och visade på ett medelvärde av erosionshastigheten på0,159 m/a för platsen vid Högklint och 0,123 m/a för platsen vid Gråberget. Klintarna undersöktes ocksåmed en Schmidt-hammare. Resultatet visar hur klippväggen är mer eroderad under den synliga grundvattennivånän över den. Mellan oktober 2012 och maj 2013 mättes temperaturen på klintväggen, samt4,5 cm och 9,5 cm inne i berget, med hjälp av Gimini Tinytag datainsamlare. Resultatet visar att temperaturenlåg inom spannet för frostsprängning, dvs -10 till -3 ºC, i sammanlagt 19,7 dygn. Dessa lågatemperaturer tillsammans med den höga andelen synligt vatten i klinten möjliggör för bildandet avsegregationsis inne i klinten. Detta kan vara en bidragande orsak till uppluckring av klintväggen ocherosion i området.En betydande del av klinterosionen längs med kusten sker på grund av grund-, smält-, och regnvatten,kanske till och med i högre grad än brytande vågor. Det är viktigt att Gotlands kommun vidtar åtgärderför att förhindra skada på egendom och personskador. Mer studier behövs för att ta reda på hur framtidaklimatförändringar kommer att påverka klintarna och erosionshastigheten längs med kusten.
