Ryoanji

Ryoanji (Ryōan-ji) is a Zen Buddhist temple in Kyoto, Japan which is today most famous for its Zen rock garden with its enigmatic arrangement of stones. Founded in the 15th century CE, the temple is one of the most visited tourist spots in Japan and is listed by UNESCO as a World Heritage Site.

Foundation

The site of Ryoanji, located in the northern hills of Kyoto (Heiankyo) in the district of Ukyo-ku, was converted into a Buddhist temple in 1473 CE. Before that, it was a private estate, created in 1450 CE and owned by the influential Hosokawa family. The gardens were modelled during the ownership of Hosokawa Katsumoto (1430-1473 CE), who retired there, and when the famous general and one of the deputies to the shogun Ashikaga Yoshimasa (r. 1449-1473 CE) died, the buildings were converted for use as a Zen Buddhist temple site.

Zen was introduced to Japan from China in the 12th-13th century CE, and it became especially popular from the mid-15th century CE. Zen thought reduces the significance of studying sacred texts and instead emphasises the importance of contemplation (son) in order to reach enlightenment. Certain things may assist an individual in their process of contemplation and one of these, as we shall see, is the use of minimalist rock gardens.

The Hojo Hall in the complex was once the abbot's residence and its interior is today divided into six rooms by painted sliding screens (fusuma) which include several fine depictions of dragons. There is another building next to the Hojo Hall which is today used as living quarters by the monks of Ryoanji.

Roman Glass

Roman glassware includes some of the finest pieces of art ever produced in antiquity and the very best were valued higher than wares made with precious metals. However, plain glass vessels such as cups, bowls, plates, and bottles were also used as everyday containers, in particular, for storing and serving food and drinks. Glass was also used by the Romans for its decorative qualities and could be incorporated in mosaics and decorative panels in both walls and furniture. The material was also used for windows, to create jewellery, mirrors, game pieces, magnifying glasses, sculpture and, in the form of powder, even as a medicine and toothpaste.

Materials

The use of the man-made material called glass - a mix of soda, silica, and lime - pre-dates the Romans by over 1,500 years, but even they seem not to have fully understood the complexity of the component mix and the necessity for lime to make the glass impervious to water and much more durable to the ravages of time and use. Lime can be found naturally, for example, as part of the silica component in the form of sand which contains a significant percentage of crushed sea shells. Indeed, two areas became noted for the high quality of their glass - along the Belarus River in Phoenicia and the Volturnus River in Campania - not coincidentally, areas where the sand was particularly rich in lime. However, some Roman glassmakers, perhaps without knowing exactly why, did understand that the addition of small pebbles and shells could affect the final quality of the glass produced.
