 kneeling human skeleton, with the words ‘Ne reminiscaris domine delicta nostra nec delicta nostrorum parentum.’ The figure is supposed to be a memorial of Sir Henry, whose arms are figured in the glass.

 HEYDON, JOHN (d. 1653), military commander and mathematician, was the second son of Sir Christopher Heydon [q. v.] According to Wood, he was a distinguished soldier, and also an eminent scholar, being especially skilled in mathematics. In 1613 he was keeper of the stores in Sandown Castle, Deal, Kent. He was knighted in August 1620. In 1627 he was appointed lieutenant of the ordnance in the place of his brother Sir William, who was killed in the Isle of Rhé. Between 1627 and 1643 he was actively occupied in furnishing men, provisions, arms, guns, and ammunition for the service of the king (Cal. State Papers, Dom. 1627–43). When Charles I raised his standard at Nottingham 22 Aug. 1642, Heydon was in charge of cannon and ammunition at York. He soon joined the king, and accompanied the royalist army from Shrewsbury towards London in October 1642 (, Hist. ed. Macray, ii. 293, 346). He acted as lieutenant-general of the ordnance with Charles's forces, and joined his privy council. He was made D.C.L. at Oxford on 20 Dec. 1642. Heydon suffered much for the king's cause. His goods were sequestrated, and there is an inventory of them in the British Museum, entitled ‘Inventarye of part of the Goods and Chattells of Sr John Hayden, knight, taken the 28 of Julye 1643,’ and also of ‘the goodes of Edward Stevens, seruant of Sir John Hayden, knight’ (Add. MS. 28191 d). Heydon died on 16 Oct. 1653.

 HEYDON, JOHN (fl. 1667), astrologer and attorney, son of Francis Heydon of Sidmouth in Devonshire, by Mary Chandler of Worcestershire, was born at his father's house in Green Arbour, London, 10 Sept. 1629, and baptised at St. Sepulchre's Church. His father belonged to the Devonshire branch of the family of Heydon of Norfolk. According to his own account (Introduction to the Holy Guide) he was educated at Tardebigg in Worcestershire among his mother's friends at first by John Dennis and afterwards by the Rev. George Linacre. In consequence of the outbreak of the civil war he did not go to the university, but is said to have joined the king's army; the statement that he commanded a troop of horse at Edgehill cannot be accepted if he has given the date of his birth correctly. In 1651 he went abroad, and of the next few years he gives the following account: ‘It was,’ he says, ‘my fortune to travel into other countreys, first with a merchant, as factor; he dyed; afterwards I was forced to exercise myself in martial disciplines in Spain and Turkey,’ and after many adventures ‘went to Zant, from thence carried to Sevel, and then to the Spaw, and when I came to England I followed the law, and gave a very ignorant fellow five-and-thirty pounds to instruct me in that honourable profession; he, like a duns, took my money and left me as ignorant as when I came to him; it was my good hap to meet with an honest man, and by his instructions I came to be what I am’ (Introd. to the Prophetical Trumpeter). He was ‘indented a clark’ 20 June 1652. In 1655 he was living in Clifford's Inn, practising as an attorney and casting nativities, but probably about that time he was imprisoned by the Protector's order in Lambeth House and his books burnt. The reason Heydon assigned was that he had foretold the date of Cromwell's death by hanging (cf., Ormonde, ed. 1851, iv. 293). He continued in confinement for two years. In 1659 he complains he was ‘vext with law suites,’ and he hints that it was on his wife's account.

Heydon was intimate with all the astrologers of the Restoration. In 1662 he fell out with Lilly, whom he termed ‘sterquilini filius,’ but in 1664 he made offers of friendship, attributing the misunderstanding to the insinuations of John Gadbury [q. v.], formerly a friend of Heydon, who had recently cheated him out of 10l.

In 1663 Heydon was arrested and confined for a few weeks in the Gatehouse during his examination on a charge of putting treasonable matter into books which he took to Lillicraft to be printed. He also seems in 1664 to have suffered imprisonment for debt, from which he said he was released by the good offices of the Duke of Buckingham. Heydon's house after 1658 was ‘in Spittalfields, near Bishopsgate, next door to the Red Lion.’ In 1667 he was again in prison, this time accused of ‘treasonable practices in sowing sedition in the navy, and engaging persons in a conspiracy to seize the Tower.’ It was alleged that his patron Buckingham had
