With its products, Calchèra San Giorgio always endeavors to meet the requests of monument authorities and designers. The raw materials used are natural and pure, selected according to time-honored traditions from classical literature and the craftsmanship of past centuries. All products are subject to strict production control, are CE certified and comply with European quality standards. By analyzing and studying ancient mortars, plasters and their formulas to produce specific materials for the restoration, reconstruction, consolidation of listed buildings and for sustainable, organic construction. Calchèra San Giorgio also provides trained specialists for analysis in the field of restoration. The studies are followed by detailed technical reports on the condition, damage and composition of the materials.

Calcedicampo base plaster is highly breathable, open to diffusion, very porous and hygroscopic, has thermal insulation properties, is mold-resistant and environmentally friendly. It is a product made from pure, recycled raw materials from the agricultural, food and brick industries. It is composed of pure, natural lime and granules from eggshells, amorphous ash from rice husks and cocciopesto – grit and flour in continuous grading and from bricks fired at low temperatures. The mortar is free of substances that are harmful to health and the environment. Calcedicampo base plaster is used to regulate and optimize the thermal and hygrometric situation in rooms. Condensation and mold form due to vapor-tight insulation materials on the outside, low diffusion capacity of the walls and/or thermal bridges. Thanks to its special composition and the resulting properties, Calcedicampo organic base plaster ensures a healthy indoor climate. It is ideal for sustainable, ecological, organic construction and renovation. Thanks to its excellent MBV value, Calcedicampo is a good substitute for clay plaster. This characteristic was tested and confirmed by measuring the Moisture Buffering Value Ideal (this parameter determines the amount of water vapor that is absorbed and released over a certain period of time in the event of fluctuations in relative humidity). The basecoat plaster also has high compressive strength and durability. The base coat is environmentally friendly, reduces CO2 emissions and reduces the consumption of raw materials. It is ideal for indoor and outdoor areas, on old and new masonry made of stone, brick, mixed masonry, concrete, aerated concrete, hemp bricks, rushes (reed mats), bamboo and straw. The plaster mortar has excellent compatibility with antique and historical materials and is therefore also recommended for the restoration of listed buildings. In the case of concrete and aerated concrete, the air, material and substrate temperature must be between +5°C and +35°C during application and the setting process. Concrete and aerated concrete must be primed in advance with Silifix – Calchèra San Giorgio to bind the water-soluble salts contained in these building materials and prevent these salts from blooming in the plaster. After a drying time of twelve hours, Fortis Vorspritz – Calchèra San Giorgio serves as a bonding bridge.

On Open Monument Day, 7,500 monuments across Germany opened their doors – 750 in Bavaria alone. The gate of the Old Mint in Munich was also wide open, with the Bavarian State Office for the Preservation of Monuments inviting visitors to view the exhibition in the Hall of Columns. Accompanied by guided tours and lectures, the exhibition “Großbaustelle 793” ran until October 10, 2014.

Under the title “Construction site 793: Charlemagne’s canal project between the Rhine and Danube”, the exhibition presents the latest results of research into Charlemagne’s moat, the “Fossa Carolina”, as a contribution to the 1200th anniversary of his death. Charlemagne’s moat was intended to connect the Altmühl and Rezat rivers – thus the Rhine and Danube – and thus overcome the European watershed. The text walls are mounted on steel grids and probably refer to the short duration of the exhibition, but at the same time to the large-scale archaeological construction site that is still ongoing. The confirmation of written, contemporary sources on the Karlsgraben using archaeological methods is remarkable. Sharpened oak planks, lateral boundaries of the approximately six-metre-wide moat, were excavated and can be seen in the exhibition in their original form as well as reconstructed in a “walk-in moat”. Franz Herzig carried out their dendrochronological examination in Thierhaupten – and confirmed the dates given in the imperial annals for the years 791 to 793, which report on the construction of the moat in 793.

The Day of the Open Monument in Bavaria was opened the day before at Thierhaupten Monastery. Read more about this in RESTAURO 7/2014.

Hermes – More than the messenger of the gods

Hermes appears in ancient mythology as a figure who organizes transitions and productively links opposites. As a divine mediator between gods and humans, between movement and order as well as between life and death, he embodies central cultural ideas of the Greek world. The mythological figure is particularly suitable for investigating interactions between cult, art and systems of meaning in the ancient world.

The Greek world of gods is characterized by clearly defined responsibilities, but not all deities can be clearly defined. It is precisely those figures that combine several functional areas that open up a differentiated view of ancient worlds of thought and life. In archaic times, Hermes developed into a central figure of such transitional zones, whose effectiveness manifested itself in everyday religious life, in narrative myths and in visual culture. His significance is not explained by a single field of activity, but by his ability to symbolically bundle movement, exchange and mediation – from travel and trade to the guidance of souls. This makes it a key to understanding the cultural logics that shaped the Greek polis.

Mythological roles and cultic anchoring

In the Homeric hymns, Hermes appears as an early autonomously acting deity whose characteristics are already programmatically developed in the myth. The famous theft of Apollo’s cattle is to be read less as a moral transgression than as a narrative demonstration of intelligence, agility, knowledge of rules and rhetorical skill. These characteristics point to a deity who does not negate orders, but shifts and readjusts them according to the situation. In addition to his function as a messenger of the gods, Hermes clearly emerges in Greek religion as a psychopompos who guides souls on their way to Hades after death. This accompanying function connects the sphere of the living with the underworld and makes Hermes a mediator at one of the most radical boundaries of human existence.
This role found a concrete counterpart in cult practice: herms – cuboid pillars with the head of the god and often a phallic relief – were erected at crossroads, property boundaries, doorsteps and city gates, offering protection, orientation and legal markings at the same time. Such objects combined religious worship with social order, marked borders and paths, protected travelers and traders and made crossings visible and controllable. The cult of Hermes was particularly widespread in Arcadia and Attica in the Archaic and Classical periods; Mount Kyllene in Arcadia was considered the time-honored birthplace, from where its worship spread to other regions. The importance of the herms for the functioning of the polis is dramatically demonstrated by the famous desecration of the herms in Athens in 415 BC, when numerous public herms were mutilated in one night and a political-religious scandal arose that shook confidence in the order, omens and security of the city. The violent reaction of the Athenians – including trials, exile and political purges – illustrates how closely religious symbols, public space and polis-communal identity were linked.

Pictorial representation and artistic concepts

A comparatively stable iconographic repertoire developed in the visual arts of antiquity. Hermes was often depicted as a youthful, athletic body, equipped with winged sandals, a traveling hat (petasos) and the herald’s staff (kerykeion) as a sign of mediation. These attributes refer to speed, communication, trade and protection, but at the same time to a controlled, idealized physicality. Classical sculptures in particular, such as the “Hermes with the Dionysus Boy” from Olympia, which has been attributed to Praxiteles since antiquity, show Hermes as a resting figure with latent potential for movement, emphasizing the balance between dynamism and order. Attic vase painting from the 6th and 5th centuries BC also takes up these pictorial formulas, for example in scenes of soul guidance, errands between gods and humans or the accompaniment of other deities. In funerary iconography, Hermes Psychopompos appears as a discreet but present figure who frames the moment of farewell and structures the transition to the sphere beyond; his travel attributes no longer merely mark profane movement, but emphasize his ability to move safely between different worlds.

Transformations and cultural repercussions

In Roman antiquity, Hermes merged with Mercury, whereby the focus of his responsibilities shifted more towards trade, transportation, economic exchange and the urban economy, without completely displacing older functions such as the role of messenger and psychopompos. This adaptation illustrates how mythological figures remained adaptable to new social, political and economic contexts. In the European Renaissance, the ancient deity – now mostly under the name of Mercury – was received as an allegory of eloquence, learned mediation, inspiration and rapid intelligence. Humanist pictorial programmes drew on him to symbolize intellectual agility, diplomatic skill and rhetorical competence, for example in emblem books, ceiling paintings or courtly allegories. The figure thus became part of a long-term traditional context in which ancient systems of meaning were repeatedly reinterpreted, recoded and functionalized.
Even today, Hermes – often conveyed through the figure of Mercury – stands for mobility, communication, trade and the productive handling of borders, which is why his symbolism remains understandable even in modern cultural contexts. In art and cultural history, the figure proves to be a connecting element between religious practice, visual design and social order. Its enduring presence shows that ancient myths are less to be understood as rigid traditions than as flexible interpretations that can be adapted to changing cultural issues and constantly updated.
