Little is known of Crane’s origins, though the union of his sisters with minor Cornish gentlemen lends some credence to an undocumented claim that he came from Camborne in Cornwall.
When the duchy of Cornwall’s administration was reconstituted in 1616-17, Crane secured the post of auditor-general, with a broad oversight of all Prince Charles’s finances. His new status was confirmed by a knighthood in September 1617. Although Crane maintained his links to Lennox, who in about 1618 helped him with the financial provision for his marriage settlement, his career was increasingly shaped by his royal service. His proposal in 1619 to establish a tapestry factory at Mortlake depended on Crown backing, and was almost certainly a royal initiative, intended to emulate the works founded in 1607 by Henri IV of France. Crane’s visit in 1618 to Flanders, ostensibly to Spa, may in fact have been an exploratory mission for this project, since the first stage in setting up the Mortlake factory involved the importation of skilled Flemish tapissiers. The project was financed initially by the grant of the fees arising from the sale of three new baronetcies. Although by mid-1620 Crane was experiencing difficulties in collecting the money owed by Sir Samuel Tryon, work began that autumn on the first suite of tapestries, a Crown commission.
In the 1621 Parliament Crane again sat for Penryn. He presented the bankruptcy bill on 1 Mar., supported an import ban on Spanish tobacco (10 Apr.), and was named to a committee which was instructed to prepare bills on alehouse regulation, the sale of horsemeat and the clerk of the market’s regional jurisdiction (24 April).
The first suite of Mortlake tapestries, which depicted a conventional Flemish subject, the myth of Vulcan and Venus, was completed in June 1622. The Crown now acted to consolidate the project, and in 1623 the king hired a new designer, Francis Cleyn, while Prince Charles purchased Raphael’s famous designs for papal tapestries. However, the Mortlake finances remained precarious, and in the spring of that year Crane, as the factory’s director, appealed to James for fresh resources, claiming that he had personally sustained a loss of more than £13,500 on the project, and was therefore unable to raise further capital himself. Faced with the prospect that the works might collapse without Crown intervention, Prince Charles provided £500, while the king, under pressure from the duke of Buckingham, agreed to contribute an additional £2,500 in June 1623 by way of a grant of the fees arising from the creation of five serjeants-at-law. These measures eased Crane’s immediate problems, and in the following year he took steps to enhance production. Describing himself to Buckingham as ‘destined for adventures’, he explored the possibility of exports to Persia and in 1624 arranged for tapestries to be shipped out by the East India Company. However, he failed to secure his dividend payments from the Company in silk rather than money.
Crane’s continuing favour with Charles was confirmed by his promotion in early 1623 to the Prince’s Council, and he was returned to the 1624 Parliament for Launceston as the Council’s nominee. In the Commons Crane was mainly associated with Crown and duchy business. Among the subjects covered by the committees to which he was named were bills to facilitate leases of duchy property (9 Mar.), confirm a land transaction between Prince Charles and Lady Alice Dudley (23 Mar.), remove brewhouses from the vicinity of royal residencies, and allow the king to acquire York House (both 19 May). Another of his committee nominations related to the subpoena office, which was run by his duchy colleague Sir Henry Vane* (22 April). Crane was also named to a legislative committee reviewing the New River project (22 Mar.), and to conferences on bills concerned with recusancy and monopolies (3 and 7 April).
Prince Charles’s accession to the throne in 1625 brought a general enhancement of Crane’s position. In May he was granted an annuity of £2,000 for ten years, half of which was to serve as a part-payment for existing tapestries, with the remainder intended to encourage future work. Two months later the king also provided for repayment of a loan to the Crown which Crane had been required to make in 1624. At about the same time, he obtained a patent for making farthing tokens, which he held jointly with the dowager duchess of Lennox, widow of his old patron, though enforcement of this monopoly proved troublesome.
The late 1620s saw Crane’s career reach its peak. Mortlake was now producing the highest-quality tapestries in Europe, and purchasers included Buckingham and lord keeper Williams. The East Indies venture was not a great success, but the first consignment of tapestries eventually brought a return of £3,000, and by late 1628 Crane was contemplating a renewed assault on this market.
In 1630 Dru Burton, Crane’s deputy as duchy auditor-general, approached the government with allegations that royal projects and subsidies at Mortlake had resulted in undisclosed profits totalling as much as £12,255. Crane promptly dismissed Burton, and though there was apparently some substance to these claims, the Crown showed reluctance to act on his report.
In early 1636 the king owed £2,872 for tapestries, which may explain why Crane apparently had no difficulty in February in renewing his farthing token patent, this time in partnership with Lord Maltravers, who had taken over the duchess of Lennox’s interest. Crane had evidently consolidated his relationship with Arundel’s son, who assisted him with the Woodrising purchase and shared his new-found enthusiasm for fen drainage.
