During the course of browsing through diocesan archives at the National Library of Wales some years ago, I noticed an abrupt change of policy in the commissioning of stained glass in the Diocese of Llandaff in the late 1950s. The change was from the endorsement of quite conservative design, and the avoidance of additional background detail and ornament, to a much more colourful and modern approach to stained glass design. There was also a concerted encouragement to commission stained glass by Welsh artists, which chiefly benefited the firm of Celtic Studios, in Swansea, and John Petts.
I noted this in Stained Glass from Welsh Churches (p. 268–9), and expanded upon it in a lecture given in Cambridge in 2016. This has now been published in my first article for the Journal of Stained Glass (vol. 42, 2018), and illustrates windows that I would have liked to have included in Stained Glass from Welsh Churches but didn’t have the space for.
One of the striking things about the distribution of stained glass by Celtic Studios is that, although their windows are found widely across the whole of south Wales, few were commissioned for churches in Cardiff. I pointed this out in a footnote to Stained Glass from Welsh Churches on p. 248, noting that windows by the firm in Cardiff were limited to two Anglican churches, a Presbyterian church and a synagogue. As a result of some recent fieldwork, one of these Anglican churches can be crossed off the list. A ‘major early window’ of theirs is mentioned by John Newman in the Pevsner (The Buildings of Wales: Glamorgan, 1995, p. 313) at St Mary’s, Whitchurch, and although it is not listed in the appendix of Maurice Broady’s study of the firm (A Vision Fulfilled, 2010), I did not question Newman’s reference as the window was described as ‘signed and dated 1948’.
I recently arranged to visit St Mary’s, which is usually locked, and discovered that this impressive window is in fact signed and dated, but by Powell’s of Whitefriars, and not by Celtic Studios at all.
Reflecting on this, and looking again at post-war commissions for stained glass in and around Cardiff, I feel that perhaps I should have given a little more weight to the number of these commissions that went to Powell’s in the 1940s and 50s, which included the replacement east window for St Margaret’s, Roath (Cardiff), a major work alongside that at Whitchurch and others. These are enumerated in Dennis Hadley’s list of works by Powell’s, compiled from their archives at the V&A in London. But, strangely, the west window at Whitchurch is not among them, although two earlier windows by them at the church are listed.
