Camelio was born either at Venice or Vincenza. He was a fine engraver and medallist, and is considered by Nägler to have invented the process of striking coins and medals from steel dies. He was especially noted for light steel armour of high temper. He was granted a patent or concession for the sole working of his invention by the Senate of Venice from 1509 for five years. [Sidenote: _Bartolomeo Campi_, Pesaro, Venice, Paris, 1573.] Campi was born at Pesaro, but the exact date of his birth is unknown. He was a goldsmith, and engraver and maker of arms and armour of such merit that they elicited the highest praise from Pedro Aretino in his letters from Venice to Bartolomeo Egnazio in 1545. About this date he made a magnificent pageant suit of pseudo-Roman armour for Guidobaldo II, Duke of Urbino, who presented it to Charles V. The cuirass is superbly modelled on the human torse and is decorated with a Medusa’s head and bands of gold with silver flowers. The shoulder-pieces are of blackened steel in the form of masks with golden eyes, and the lambrequins hanging from the cuirass end in medallions and masks. The helmet is decorated with a crown of golden leaves. On the cuirass is the inscription: “BARTOLOMEVS CAMPI AVRIFEX TOTIVS OPERIS ARTIFEX QVOD ANNO INTEGRO INDIGEBAT PRINCIPIS SVI NVTVI OBTEMPERANS GEMINATO PERFECIT.” If this inscription is not an exaggeration, it is little short of miraculous that this suit should have been made in one year. It is now at Madrid (A, 188). In 1547 Campi directed the fêtes held in honour of the marriage of Guidobaldo II and Vittoria Farnese at Pesaro. He was military engineer to the Republic of Siena, to that of Venice, and to the King of France between the years 1554 and 1560. He assisted the Duc de Guise at the siege of Calais in 1562, and in 1568 served with the Duke of Alba in Flanders, where he was given a commission as chief engineer of fortifications at a salary of 500 escudi. The Duke, writing to the King on June 3, 1569, says: “I tell your Majesty that you have a good man in Captain B. Campi, because in truth he is a soldier and has art, although not so well founded as Pachote ... and he is the best man I have met with since I have known men--I do not say only engineers, but men of any sort--very happy and steady in his work.” Campi was killed by an arquebus shot at the siege of Haarlem on March 7th, 1573, to the great grief of the Duke and the whole army. His brother was an armourer about 1555, but we have no records of his work. The magnificent specimen of Bartolomeo’s work at Madrid is the only example of his craft as an armourer that has come down to us (Plate XIV).
