Hieronymus Bosch

The art of Hieronymus Bosch has challenged and fascinated viewers since the 15th century. His hybrid creatures and creative monstrosities seem unprecedented in the art historical canon and therefore mysterious to 21st-century viewers. Adding to this general sense of bafflement is the fact that we know perhaps less about Bosch than any other artist of his era. Unlike his famous contemporaries, Albrecht Dürer and Leonardo da Vinci, who documented their lives and works in copious letters and writings, Bosch left us nothing in his own words. His date of birth is unknown, and we cannot say if he ever left his birthplace, the town of ‘s-Hertogenbosh (the modern city of den Bosch, the Netherlands), from which he took his professional name. For the most part, the art itself is all that is left us, although ironically documentation does exist for several lost paintings. Today, only about twenty-five works are accepted as by Bosch’s hand, and his name appears on only seven of these. None shows a date. With the advent of sophisticated means of technical examination of panels, even these few are being disputed. No less important is the question of meaning in Bosch’s works, which were produced at a time when artists delighted in veiling content within layers of enigma and symbolism. As scholars continue to delve into the historical and artistic contexts from which Bosch evolved, the inscrutable painter emerges as a man of his time, conversant in the historical, intellectual, and religious controversies of his day. His works reflect a tumultuous era, different from, but no less complex than, our own.

Abstract Objective To investigate systematically the presence of the Babinski sign in paintings of the Christ Child by the greatest painters of the Renaissance. Design Observational analysis. Setting Large collection of paintings depicting the Christ Child from Flemish, Rhenish, and Italian schools between 1400 and 1550 CE, searched using published catalogues and Google. Study sample 302 Renaissance paintings (by 19 painters) depicting the Christ Child. Main outcome measure Babinski sign, defined as a hallux extension with an amplitude greater than 30°. The presence of foot sole stimulation was also noted. Results An unquestionable upgoing toe was apparent in 90 (30%) of the 302 paintings. The Babinski sign was present in more than 60% of Christ Child paintings by Rogier van der Weyden, Hans Memling, Martin Schongauer, and Matthias Grünewald. A bilateral Babinski sign was observed in three paintings. Stimulation of the sole was noted in 48/90 (53%) paintings and was always present in paintings by Andrea del Verrocchio, Leonardo da Vinci, and Giorgione. No association existed between the presence of the Babinski sign and the period during which the painter was active. Conclusions Four main factors were noted in relation to the representation of the Babinski sign in paintings of the Christ Child: the physiological toe phenomenon in infants, the representation of the nudity of the Christ by painters during the 15th century to demonstrate the incarnation, Renaissance painters’ need for precise observation of anatomy, and the desire of some Rhenish and Flemish painters to depict very realistic details. Italian Renaissance painters, whether Mannerist or not, tended to idealise the beauty of human body, and they often did not reproduce the Babinski sign.

The 5th European-African Conference of Wind Engineering is hosted in Florence, Tuscany, the city and the region where, in the early 15th century, pioneers moved the first steps, laying down the foundation stones of Mechanics and Applied Sciences (including fluid mechanics). These origins are well reflected by the astonishing visionary and revolutionary studies of Leonardo Da Vinci, whose kaleidoscopic genius intended the human being to become able to fly even 500 years ago… This is why the Organising Committee has decided to pay tribute to such a Genius by choosing Leonardo's "flying sphere" as the brand of 5th EACWE.

At the end of the 15th century, Italian painters explored the new effects made possible by the use of the oil medium. They created a sense of depth and relief by following the Flemish technique of glazes, which allowed the spreading of very thin and translucent layers, rich in medium and with low pigment content. A striking example is given by the realization of the shadows in the paintings of Leonardo da Vinci: the Master used the so-called ‘sfumato’ technique based on the use of glazes to obtain a ‘smoky’ aspect for the creation of flesh tones, with very subtle contours that seem to have no hard edges. Since the 16th century, his technique was famous due to the perfection of the works of art that glazes have allowed artists to reach. Analytical characterizations of painting materials have helped us to improve our knowledge about this technique. X-ray fluorescence measurements were carried out on seven paintings by Leonardo da Vinci preserved in the Louvre museum. This technique is widely used for qualitative determination of the pigments but it is very difficult to interpret the data quantitatively in the case of layered structures such as easel paintings. As well as the characterization of the palette, we obtain in-depth information on how Leonardo modelled his shadows. Comparisons between the different paintings of Leonardo highlight the specific features in the Leonardo technique.

Ancestral Light Capture: Camera Obscura -...light rays entering the eye and light rays entering the glass globe placed inside a small camera obscura - Codex Atlanticus, fol 337, ca 1500 Leonardo Da Vinci..".I select cast off materials to create my cameras, and with them, construct an imagery that interprets the humanity of a cast off people". "A Second of Your Time" Prospect 1.5 Biennial 2010, New Orleans. I found fragments of glass bottles and glass shards, through wanderings in the back spaces of buildings behind the town square in Marion, Alabama and in the East Smithfield community in Birmingham. a community erased through highway construction. Those glass fragments (Da Vinci's" Glass Globe"), functioned as a lens for allowing the light to pass through, capturing the spiritual memories of those black folks who last touched the glass. The passage of the light from the glass fragments was embedded onto the film, which had been placed inside my small camera obscura/pinhole camera.

Leonardo da Vinci in the 16th century, used injection replica techniques to study internal surfaces of the cerebral ventricles. Developments in replicating media have made it possible for modern morphologists to examine injection replicas of lung and kidney with the scanning electron microscope (SEM). Deeply concave surfaces and interrelationships to tubular structures are difficult to examine with the SEM. Injection replicas convert concavities to convexities and tubes to rods, overcoming these difficulties.Batson's plastic was injected into the renal artery of a horse kidney. Latex was injected into the pulmonary artery and cementex in the trachea of a cat. Following polymerization the tissues were removed by digestion in concentrated HCl. Slices of dog kidney were aldehyde fixed by immersion. Rat lung was aldehyde fixed by perfusion via the trachea at 30 cm H2O. Pieces of tissue 10 x 10 x 2 mm were critical point dried using CO2. Selected areas of replicas and tissues were coated with silver and gold and examined with the SEM.

Recycling of sewage sludge will soon no longer be possible in The Netherlands, or will be possible only to a very limited degree. For that reason, part of the sewage sludge will have to be incinerated. This will happen particularly in those areas where tipping space is very limited. A sludge incineration plant is planned to be built in the town of Dordrecht, with a capacity of 45,000 tonnes dry solids per year. The plant will be subject to the very strict flue gas emission requirements of the Dutch Guideline on Incineration. The Guideline demands a sophisticated flue gas purification procedure.
