Exploring the History of the Helmdon Mantle-Tree
16 September 2025

TEP Principal Historic Environment Consultant, Amir Bassir, has recently been published in the Northamptonshire Past and Present Journal , contributing to a long-standing debate on the history of the Helmdon mantle-tree.

The Helmdon mantle-tree, once located in the parsonage house in Helmdon, Northamptonshire, has been the subject of academic interest since the 17th century. At the heart of the discussion is a date carved into the timber, which has been variously interpreted as evidence for the use of Arabic numerals in England as early as the 12th century. Over the centuries, scholars including John Wallis, John Ward, Samuel Denne and Henry Dryden have all offered competing interpretations, sparking a lively debate about medieval numeracy, architecture, and the reliability of antiquarian records.

In his article, Amir provides an overview of this historic debate and reconsiders the evidence in the context of regional architectural history. He examines how different interpretations of the date align with broader patterns in the adoption of Arabic numerals in England, as well as with the physical characteristics of the timber itself.

Amir’s contribution not only revisits an important episode in the history of mathematics and antiquarian study, but also reflects his expertise in historic building recording and vernacular architecture in the East Midlands.

For those interested in the full discussion, the article is available in the 2024 edition of Northamptonshire Past and Present (members only).

Delivering major infrastructure in sensitive environments requires a coordinated approach, bringing together a range of expertise to understand place, manage risk and support informed decision-making. Our work on the North Hykeham Relief Road (NHRR) in Lincolnshire is a strong example of this in practice, with teams from across TEP working together to support the delivery of this long-planned scheme. A long-planned piece of infrastructure The NHRR forms the final section of Lincoln’s ring road, a scheme that has been identified in Local Plans for around twenty years. As the project progressed, it required careful consideration of environmental constraints, historic assets and landscape character, alongside the practicalities of delivering a major new road. Working alongside Balfour Beatty and the wider project team, we provided a range of services spanning heritage and archaeology, planning, landscape, ecology and arboriculture. A coordinated programme of assessment and support underpinned the development of the scheme. Our Historic Environment team established the baseline through desk-based assessment, consultation and phased archaeological evaluation. This work identified areas of interest including sites of prehistoric activity, the important Roman road of Ermine Street, and a potential Roman villa complex, providing valuable insight into the long-term history of the site. These findings directly informed the design process, helping to shape the scheme in response to the site’s archaeological and historical context. The team also assessed potential impacts on sensitive heritage assets, including listed buildings and conservation areas, ensuring that the historic environment was fully considered as the project evolved.

TEP is proud to be partnered with the award-winning initiative Time for Geograph y, whic h showcases the importance of geography and the diverse careers it can lead to. Time for Geography is a free, online education platform reaching schools and universities across the UK. Through a series of engaging video resources, it brings geography to life in the classroom, connecting academic learning with real-world challenges such as sustainability, climate change, urban planning and environmental management. Our contribution to the initiative forms part of the platform’s Careers Collection, where our team shares insight into the varied and rewarding pathways geography can open up. These resources are designed to help students understand how their studies translate into professional roles, offering a clearer view of the opportunities available within the environmental sector. We’re delighted that this collaboration has been recognised with a Highly Commended Geographical Association Publishers Award , which celebrates the careers-focused videos and resources developed to guide students towards further education and careers in our industry. With an audience of over 2.5 million this year, Time for Geography is a powerful example of how education and industry can come together to inspire future talent, showing how a subject studied in the classroom can lead to meaningful, real-world careers. For many of our colleagues at TEP, that journey began with a simple interest in geography at school. Today, that interest has grown into careers spanning ecology, arboriculture, heritage, planning, landscape design and environmental management. By sharing these experiences, we hope to encourage the next generation to see geography not only as a fascinating subject, but as a pathway into work that makes a tangible difference. We’re proud to support an initiative that is helping shape the future talent pipeline for our sector, and to inspire the environmental specialists of tomorrow. Learn more and watch our video:
