Piacenza Cathedral

Piacenza Cathedral is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Piacenza Cathedral rather than just read about it. In short: Piacenza Cathedral (Italian: Duomo di Piacenza), fully the Cathedral of Santa Maria Assunta e Santa Giustina, is a Roman Catholic cathedral in Piacenza, Italy. The current structure was built between 1122 and 1233 and is one of the most valuable examples of a Romanesque cathedral in northern Italy.

Key takeaways

Piacenza Cathedral belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Piacenza Cathedral to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Piacenza Cathedral from memory before moving on to harder problems.

Reference excerpt

Piacenza Cathedral (Italian: Duomo di Piacenza), fully the Cathedral of Santa Maria Assunta e Santa Giustina, is a Roman Catholic cathedral in Piacenza, Italy. The current structure was built between 1122 and 1233 and is one of the most valuable examples of a Romanesque cathedral in northern Italy. The dedication is to the Assumption of the Virgin Mary and to Saint Justina. It is the seat of the diocese of Piacenza-Bobbio.

Architecture The cathedral has a total external length of 85 m, and a façade height of 32 m, dimensions which make it the largest Romanesque church in Emilia-Romagna. The façade, in Veronese pink marble and gilded stone, is horizontally divided by a gallery that dominates the three portals, decorated with capitals and Romanesque statues. The interior has a nave and two aisles, divided by twenty-five massive pillars. Its noteworthy frescoes were made in the 14th-16th centuries by Camillo Procaccini and Ludovico Carracci, while the frescos inside the dome are by Pier Francesco Mazzucchelli, "il Morazzone", and Guercino. The presbytery has a wooden sculpture from 1479, wooden choirstalls by Giangiacomo da Genova (1471) and 15th-century statues of the Lombard school. The crypt, on the Greek cross plan, has 108 Romanesque small columns and is home to the relics of Santa Justina, who was co-patron of Piacenza from the ninth century; to her was dedicated the first cathedral, Domus Justinae, which collapsed in 1117 after an earthquake.

History

Few remains can be traced of the earlier paleochristian basilica, as Piacenza was razed by Totila in 546, during the Gothic War. A document of 1123 describes Bishop Sigifredo of Piacenza (997–1031) as its "founder". During its history the cathedral was host to several minor composers as maestro di cappella including Francesco Maria Bazzani, and Giuseppe Nicolini.

Worked examples

Example 1 — a first encounter with Piacenza Cathedral

Start with the simplest possible case. Write down what Piacenza Cathedral claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Piacenza Cathedral before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Piacenza Cathedral ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Piacenza Cathedral

In research: Piacenza Cathedral appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Piacenza Cathedral in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Piacenza Cathedral is common in secondary-school and first-year university syllabi. It links to neighbouring topics 13th-century Roman Catholic church buildings in Italy, Buildings and structures completed in 1233, Cathedrals in Emilia-Romagna, so understanding it makes those chapters shorter.
In everyday life: Look for Piacenza Cathedral outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
