Marten was born in the parish of St. Michael, Bassishaw, the younger son of a prosperous baker. His parents have elsewhere been given as Anthony Marten, citizen and grocer of London, and Margaret, daughter of John Yate of Lydford in Berkshire; however, this identification is unlikely. The families may well have been more distantly related, but the latter had only one son, whereas our Member was certainly the younger of two brothers. He has also sometimes been confused with his wife’s kinsman, Henry Martyn*, though they do not seem to have been related by birth.
Although active as an advocate in the London courts by 1596, Marten maintained his household at Oxford for some years after his marriage to the sister of John Harding, a fellow of Magdalen College.
Marten became known for his vigorous enforcement of ecclesiastical discipline as chancellor to the bishop of London; as judge of the Admiralty, a member of the High Commission, judge of the Prerogative Court of Canterbury and dean of the Arches, he was once aptly described by James as ‘a mighty monarch in his jurisdiction over land and sea, the living and the dead’.
Buckingham’s client (Sir) John Eliot*, secured Marten a seat in the first Caroline Parliament at St. Germans, recommending him to the borough as a man of ‘great years, great knowledge, great experience, and great abilities of nature to support them’.
When the Parliament reconvened at Oxford on 1 Aug., Marten made a lengthy speech against the pardons given to Catholics at the suit of the French ambassadors.
Marten was again returned for St. Germans in 1626, this time with Eliot himself as his colleague. On 13 Feb. he spoke against a bill to subject the moral conduct of the clergy to the secular courts.
On 25 Feb. Marten was granted privilege in a Chancery suit against the bishop of Oxford.
In the impeachment proceedings against Buckingham, Marten was appointed, on 9 May, to consider how the Commons’ case should be presented to the Lords.
From the following September onwards Marten distanced himself, by agreement, from Eliot.
From 18 Apr. Marten engaged in a series of clashes with Sir Edward Coke* and other champions of the Common Law over the key issue of martial law. Marten believed that where there were soldiers there must be martial law. In such circumstances, he argued, the speedy administration of justice was of prime importance, a need which he illustrated by reference to his own office, where if he did not on occasion settle the demands of 500 sailors for their wages in a few hours, ‘I think they would tear me out of my chamber’.
Marten was appointed to attend a conference with the Lords on the liberty of the subject (23 Apr.), and to consider various bills concerning maritime and ecclesiastical measures.
In the debate of 21 May on the subscription bill, Marten declared his adherence to the Book of Common Prayer, and expressed his satisfaction at belonging to a Church which was ‘made by supreme authority, and so was no other’.
Three days later Marten was appointed to help report the outcome of a further conference with the Lords on the Petition.
On 18 June Marten and Sir Edward Coke found themselves in agreement over a petition concerning the father-in-law of Sir Edward Wardour*, William Bowdler, who had died intestate in 1625. Administration of the estate had been granted to the relatives by Marten, only to be claimed by the Exchequer on the ground that Bowdler was a bastard. In 1627 Marten had petitioned the king, together with several bishops, against this interference with the jurisdiction of the ecclesiastical courts. He now pointed to the difficulty of showing whether or not Bowdler had been a bastard, and Coke denied the Crown’s right in any case. Both were named to the committee to consider the petition (18 June).
During the second session Marten was named to bill committees for measures concerning preaching (23 Jan. 1629), judicial corruption (23 Jan.), and recusancy (28 January).
As bishop of London, Laud was convinced that Marten was ‘a schismatical puritan in his bosom’, and on the great prelate’s promotion to Canterbury, Marten lost his post as dean of the Arches.
