A 2300 year old bark shield found in Enderby, Leicestershire, in 2015 is the only known example of its type. Made from the bark of a willow tree, it has a woven basket boss, a roundwood handle, and a rim of split roundwood edging and lime bast bindings. Pre-Roman shields made from organic materials rarely survive in Britain and Ireland and those without metal components are exceptionally rare. Contemporaneous wooden shields are known from anaerobic environments in Scandinavia but, unlike Enderby, none of these has a body of tree bark. The complexity of the design of the Enderby shield, the skill with which it was made, and the similarities between this and metal examples suggests it was a tried and tested design, rather than a one-off. With no other example against which to compare it, experiments in reproducing the shield have been used as a tool for interpretation and have proved vital to understanding the original design. As a result of this research, it is proposed that this single artefact represents a more commonly available form of shield in the 1st millennium bc than does any metal enhanced version.

In 69 ce, the emperor Vitellius presented to dinner guests his ‘Shield of Minerva’, a platter filled with pike livers, pheasant and peacock brains, flamingo tongues, and lamprey milt. Just as Vitellius’ passion for food has been distorted into gluttony, so the Shield of Minerva has been misrepresented as a culinary abomination and the worst of the emperor's excesses. Modern scholarly reception of the Shield owes much to hostile ancient sources, but is also influenced by some modern culinary preferences. Critical reading of our sources reveals the dish as a mix of ingredients carefully chosen for their gustatory and visual appeal and for their political and military symbolism. Vitellius’ association of the platter with Minerva evokes her status not only as a martial deity, but also as a goddess of craft. The Shield of Minerva is revealed to be an intellectual exercise, not a symbol of gluttonous self-indulgence.

The bronze spearhead at the end of a long shaft is traditionally seen as a thrusting or throwing weapon, as seen in the movies. By examining the damage on a group of Late Bronze Age spearheads from Britain, and replicating their use in combat, the author shows that the spear was an even more versatile weapon — for throwing, thrusting and slashing (with a short shaft). The research puts a spotlight on the formidable skills developed in a Bronze Age life-time.

The Nebra disc is one of the most sensational European discoveries of the decade. It appears to carry symbols of the sun, moon and stars wrought in gold on a flat bronze disc just over a foot across (320mm). It is not only very strange, but, famously, appears to be winking, initially raising the suspicion that it may be a hoax. Scholars have, however, claimed it firmly for the Bronze Age, and the debate now moves to the matter of its meaning. Here the authors offer a subtle interpretation that sees it as the shamanistic device of a local warrior society.

This technical note describes a hinged lead alloy shielding block that could be used, in certain circumstances, for shaping a megavoltage X-ray field. The construction of the shield is described and the results of transmission and penumbra measurements are given.

1. Under laboratory conditions (25 to 27°C), female Cydia ptychora (Meyrick) laid an average of 44 eggs. 2. The egg incubation period was 5 days, while the larval developmental period lasted 7 to 10 days, and the pupal period 12 days. Thus, the total developmental period (egg to adult) lasted 24 to 27 days. The adult longevity averaged 10 days (13 to 15 days). 3. Descriptions of the different life stages and setal maps of the different larval instars are provided.
