Pinelli–Walckenaer Atlas

Pinelli–Walckenaer Atlas is a science 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 Pinelli–Walckenaer Atlas rather than just read about it. In short: The Pinelli–Walckenaer Atlas is a late 14th-century atlas of portolan charts, explicitly dated 1384, primarily composed by an anonymous Venetian cartographer, and held by the British Library. Background The Pinelli-Walckenaer atlas was primarily composed by an anonymous Venetian cartographer (although some suggest Genoese), probably the same person who made the similar Corbitis Atlas.

Key takeaways

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

Reference excerpt

The Pinelli–Walckenaer Atlas is a late 14th-century atlas of portolan charts, explicitly dated 1384, primarily composed by an anonymous Venetian cartographer, and held by the British Library.

Background

The Pinelli-Walckenaer atlas was primarily composed by an anonymous Venetian cartographer (although some suggest Genoese), probably the same person who made the similar Corbitis Atlas. The Pinelli-Walckenaer atlas is explicitly dated 1384 (according to its calendar), but some scholars believe it to have been made a little later (c. 1410). Two of the charts in the atlas (the specific charts for the Aegean and the Adriatic) were definitely later additions by someone else and not part of the original atlas. One suggestion is that the latter two charts were made by the Venetian cartographer Francesco de Cesanis around 1434. The calendar itself might date from 1458. The name of the atlas refers to its previous owners. It was in the possession of the Pinelli family of Venice, which owned the atlas for many years, until it was purchased in 1790 by the Baron Charles Athanase Walckenaer of Paris. The Pinelli-Walckenaer atlas is currently held by the British Library (Add MS, 19510) in London.

Features The Pinelli-Walckenaer atlas is composed of seven sheets:

astronomical calendar South Atlantic (Iberian Peninsula and northwest Africa) North Atlantic and west Mediterranean (incl. British isles) East Mediterranean and Black Sea Central Mediterranean Adriatic Sea Aegean Sea The first calendar sheet explicitly dates the atlas 1384. Sheets 1-5 were made by the same anonymous person in the late 14th or early 15th century, while sheets 6-7 were made by someone else (possibly Cesanis) in the second quarter of the 15th century.

Worked examples

Example 1 — a first encounter with Pinelli–Walckenaer Atlas

Start with the simplest possible case. Write down what Pinelli–Walckenaer Atlas claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Pinelli–Walckenaer Atlas 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 Pinelli–Walckenaer Atlas 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 Pinelli–Walckenaer Atlas

In research: Pinelli–Walckenaer Atlas appears in science 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 Pinelli–Walckenaer Atlas 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: Pinelli–Walckenaer Atlas is common in secondary-school and first-year university syllabi. It links to neighbouring topics Atlases, so understanding it makes those chapters shorter.
In everyday life: Look for Pinelli–Walckenaer Atlas 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.
