Jacopo Bassano freskomaalarina : Cartiglianon ja Enegon kirkkojen freskot: konteksti, rekonstruktio ja tulkinta

The object of this study is Jacopo Bassano (c. 1510 1592) as a fresco painter and the significance of frescoes in his late production. The research focuses on the only surviving cycle of frescoes of his later years in the Cartigliano parish church, bearing the date 1575. The other cycle studied here was painted for the 16th century parish church of Enego. It contained one of the most extensive fresco decorations executed by Jacopo Bassano together with his eldest son Francesco. However, nothing has survived of the fresco cycle and the ceiling paintings of the church, nor is any visual documentation of them left. Only the small altarpiece attributed to Jacopo Bassano and depicting Saints Justine, Sebastian, Anthony Abbott, and Roch (dated to c. 1555/1560) has been preserved. I have suggested that the frescoes of the Cartigliano parish church should be examined in the interpretational context of the spirituality of the post-Tridentine period. This period frames the historical context for the frescoes and functions as a basis for the iconographical interpretation that I have proposed. I have shown that the iconographic programme of the frescoes in the choir of the Cartigliano parish church has obvious points of contact with the Catholic doctrines reconfirmed by the Council of Trent (1545 1563). I also argue that the fresco cycle and the ceiling paintings of the Enego church should be placed in the same interpretational context as the frescoes of Cartigliano. I present a reconstruction of the frescoes in the choir attributed to Jacopo Bassano and of those on the walls of the nave attributed to his son Francesco Bassano. According to my reconstruction, the frescoes in the choir and nave walls formed a coherent cycle with a unitary iconographic programme which included the 28 paintings with Old Testament subjects in the nave ceiling. The reconstruction includes the dating and the iconography of the fresco programme and its interpretative basis. The reconstruction is based on visitation records and inventories from the 16th and 17th centuries as well as on the oldest relevant literature, namely the descriptions offered by Carlo Ridolfi (1648) and G. B. Verci (1775). I also consider the relationship of the large compositional sketches attributed to Jacopo Bassano and depicting Christological subjects to the lost frescoes in Enego. These studies have been executed with coloured chalks, and many of them are also dated 1568 or 1569 by the painter. I suggest in this study that these large studies in coloured chalks were preparatory drawings for the fresco cycle in Enego, depicting scenes from the life and suffering of Christ. All the subjects of the aforesaid drawings were included in the Enego cycle.

Kauppa, verkosto ja kaapparisota : Turkulaisen kirkonmiehen Paavali Scheelin ja Danzigin porvarin Hans Chonnertin kauppayhteydet 1509–1516

Työ on tapaustutkimus turkulaisen arkkidiakonin ja tuomiorovastin Paavali Scheelin ja Danzigin porvarin Hans Chonnertin sekä tämän pojan Hans Chonnert nuoremman kaupankäynnistä ja kaupan organisaatiosta. Työn pääasiallisena lähdeaineistona on käytetty Paavali Scheelin kirjekokoelmaa vuosilta 1509–1516. Suomen keskiajan lähteiden joukossa ainutlaatuinen kirjekokoelma mahdollistaa henkilötasolle ulottuvan tarkastelun sekä kaupassa ja henkilöverkostossa ilmenevien muutosten seuraamisen. Kirjekokoelman ohella on käytetty laajasti muita Itämeren piirin editoituja aikalaislähteitä. Aineiston lähiluvulla on hahmoteltu Scheelin ja Chonnertin kauppaverkosto: kaupan kannalta keskeiset henkilösuhteet ja henkilösuhteiden merkitys kaupassa. Verkoston kannalta olennaista on henkilöiden erilaisten roolien erottelu sekä kauppiaan, laivurin, lähetin ja velallisen roolien merkitys kauppaverkostossa. Scheelin ja Chonnertin kauppakontaktit osuvat osittain samalle ajalle Itämerellä 1500-luvun alussa käytyjen sotien kanssa. Tanskan ja Ruotsin unionikiistat sekä Tanskan ja Lyypekin (hansan) väliset kauppakiistat johtivat 1500-luvun alussa monivuotisiin sotiin, joiden yhteisenä piirteenä oli kaapparitoiminta vastustajan rannikoilla ja Itämeren keskeisillä kauppareiteillä. Itämeren kaapparisota muodostaa Scheelin ja Chonnertin kauppaverkoston kontekstin vuosina 1509–1512. Kaapparisodan loppuminen vuonna 1512 mahdollistaa Scheelin ja Chonnertin kauppaverkoston sodan- ja rauhanajan organisaation ja toiminnan vertailun. Scheelin ja Chonnertin kauppaverkoston ytimen muodosti pieni kauppiaiden ydinjoukko, johon kuului Turussa sekä kirkonmiehiä että porvareita. Ydinjoukon toiminta perustui luottamukseen, luottoihin, henkilökohtaisiin ystävyyssuhteisiin ja tiiviiseen informaation vaihtoon kirjeitse tai lähettien välityksellä. Vaikka purjehdus oli kaupankäynnin elinehto, laivureiden rooli kauppaverkostossa oli toissijainen. Sodan loppuminen Itämerellä johti laivureiden täydelliseen vaihtumiseen vuosien 1512–1513 aikana. Kauppaverkoston ydinryhmä sen sijaan säilyi samana, ja sen yhteistoiminta tiivistyi. Laajemmassa kontekstissa tapaustutkimus johtaa kolmeen päätelmään: 1) Paavali Scheelin omissa nimissään käymä kauppa oli normaali osa Turun tuomiokapitulin toimintaa; 2) turkulaiset kirkonmiehet ja porvarit tekivät kaupan saralla pitkälle menevää yhteistyötä, ja heidän kauppaverkostonsa olivat kytköksissä toisiinsa; 3) tanskalaisten monivuotinen kaapparitoiminta ei estänyt kaupankäyntiä Turun ja Danzigin välillä.

Agronomic challenges for organic crop husbandry

With respect to resource management and environmental impact, organic farming offers rationales for agricultural sustainability. However, agronomic productivity is usually higher with conventional farming. This work aimed at investigating two factors of major importance for the agronomic productivity of organic crop husbandry, nitrogen (N) supply through symbiotic N fixation (SNF) and weed occurrence. Perennial red clover-grass leys and spring cereal crops subjected to regular agricultural practices were studied on 34 organic farms located in the southern and the north-western coastal regions of Finland. Herbage growth, clover content as a proportion of the ley and extent of SNF in perennial leys, and the occurrence of weed species and weed-crop competition in spring cereal stands were related to climate conditions, soil properties, and management measures. The herbage accumulated from the first and the second cut of one- and two-year-old leys averaged 7.5 t DM ha-1 (SD ± 1.7 t DM ha-1); the clover content averaged 43.9% (SD ± 18.8%). Along with the clover content, herbage production decreased with ley age. Radiation use efficiency (RUE) correlated positively with clover proportion but despite low clover contents, three-year-old leys were still productive with regard to RUE. SNF in the accumulated annual growth of one- and two-year-old leys averaged 247.5 kg N ha-1 yr-1 (SD ± 114.4 kg N ha-1 yr-1). It was supposed that if red clover-grass leys constituted 40% of the rotation, then the mean N supply by SNF would be able to sustain two or three succeeding cereal crops (green manure and forage ley, respectively), yielding 3.0 to 4.0 t grain ha-1. Being a function of clover biomass, the SNF increased from the first to the second cut and thereafter declined with ley age. Coefficients of variation of clover contents (and SNF) between and within fields were around 50%, which was about twice as high as those of herbage production. The lower were the clover contents, the higher were the within-field variations of clover as a proportion of the ley. Low clover contents in one-year-old leys and increasing variability with ley age suggested that red clover growth was limited by poor establishment and poor overwintering. The proportions of clover in leys were lower and their variability was higher in the northwest than in the south. Soil properties, primarily texture and structure, had a major impact on clover proportion and herbage production, which largely explained regional differences in ley growth. Within-field variability of soil properties can be amended through site-specific measures, including drainage, liming, and applications of organic manures and mineral fertilizers. Overwintering and the persistence of leys can be improved by the choice of winter-hardy varieties, careful establishment and the appropriate harvest regime. Mean grain yields of spring cereal crops amounted to 3.2 t ha-1 in the south and 3.6 t ha-1 in the northwest. At 570 and 565 m-2 for the south and northwest respectively, mean weed densities did not differ between the regions, whereas the respective mean weed biomass of 697 and 1594 kg dry weight ha-1, respectively did differ. Weed abundance varied remarkably between single fields. The number of weed species was higher in the south than in the northwest. For example, Fumaria officinalis and Lamium spp. were found only in the south. Frequencies and abundances of Lapsana communis, Myosotis arvensis, Polygonum aviculare, Tripleurospermum inodorum, and Vicia spp. were higher in the south, whereas those of Elymus repens, Persicaria spp. and Spergula arvensis were higher in the northwest. The number of years since conversion to organic farming, i.e. long-term management, was one of the variables that explained the abundance of single weed species. E. repens was the weed species whose biomass increased most with the duration of organic farming. Another significant variable was crop biomass, which was affected by short-term management. The presence of different weed species was related to the duration of organic farming and to low crop yield. This finding demonstrated that it was not the organic farming regime per se, which resulted in high weed infestation and low yielding crops, but failures in the understanding and the management of organic farming systems. Successful weed control relies on farm- and field-specific long- and short-term management approaches. The agronomic productivity of ley and spring cereal crops managed by full-time farmers with an interest in organic farming was on the same level as of the mean for conventional farming. Given the many options for further improvements of the agronomic performance of organic arable systems, organic farming offers foundations for the development of sustainable agriculture. The main threat to the sustainability of farming in Finland, both conventional and organic, is the spatial separation of crop production and animal husbandry by region, along with the simplification of associated crop rotations.
