John III Crispo

John III Crispo 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 John III Crispo rather than just read about it. In short: John III Crispo (Italian: Giovanni III Crispo) was the eighteenth Duke of the Archipelago, ruling from 1480 when he succeeded his brother, Giacomo III Crispo (r. 1463–1480). Shortly after this, he reincorporated Santorini, which had been ruled by Domenico Pisani, husband of his niece Fiorenza Crispo, into the Duchy.

Key takeaways

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

Reference excerpt

John III Crispo (Italian: Giovanni III Crispo) was the eighteenth Duke of the Archipelago, ruling from 1480 when he succeeded his brother, Giacomo III Crispo (r. 1463–1480). Shortly after this, he reincorporated Santorini, which had been ruled by Domenico Pisani, husband of his niece Fiorenza Crispo, into the Duchy. His raising of taxes made him very unpopular among the Greek population of Naxos, however. They rebelled under their own magnates (archontes), and the Crispi and the other Catholic families loyal to them were shut in the island's citadel (Kastro) and were besieged by the rebels. Only the timely arrival of galleys from the Knights Hospitaller of Rhodes rescued Crispo and put an end to the revolt. The discontent did not subside, however, and in 1494 John was killed, apparently by poison, by the locals, who sent an embassy to Venice requesting for the Republic to assume control of the island, as John's sole heir, his son Francesco III Crispo, was underage. In the end, Francesco assumed his father's position in 1500.

Family He was married to a Morosini and had issue:

Francesco III Crispo Giovanni (John) also had a Mistress, his cousin, Maria Crispo, daughter of Anthony Crispo Lord of Syros (Sira). They had issue:

A daughter, name currently unknown. A son, Nicholas Antonio Crispo de Syra (Sira). married to Taddea Sommaripa fled to Rhodes Island circa 1520. 1.6 Giorgio Crispo de Syra (de Sira), de Jure Signore di Syra, (1540 -), Official of the Order of St John in Malta 1550, married (1) (c. 1550) to Norella de Fantino, married Malta (2) (c. 1585) to Leonora N, with issue.

Worked examples

Example 1 — a first encounter with John III Crispo

Start with the simplest possible case. Write down what John III Crispo 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 John III Crispo 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 John III Crispo 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 John III Crispo

In research: John III Crispo 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 John III Crispo 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: John III Crispo is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1494 deaths, 15th-century people from the Republic of Venice, Deaths by poisoning, so understanding it makes those chapters shorter.
In everyday life: Look for John III Crispo 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.
