Pins and even more so needles are an archaeological problem - because... yes, you have guessed it: they are so small. This means that unless there is a nest of pins or needles (like we once discovered in a church excavation on the women's side of the aisle, pins upon pins upon pins, probably lost during service and not retrievable, because they fell through the spaces between wooden floorboards) or unless there is a huge stroke of luck, these tiny metal rods will never be found. If they ever survived the corrosive surroundings in damp soil, that is - something that iron or steel might not take as kindly as copper alloy. And then these rare items are so much overlooked - because duh, of course they had needles, that's an everyday item, isn't it? - that there is no collation of needle articles or archaeological needle knowledge yet.
So LH folks today are faced with a problem: What to sew with? Which time knew what kinds of needles or other sewing implements? (And archaeologists as well, should they want to write about needles.)
We have two possible ways to find out what needles were in use. One way is to find surviving specimens, analyse them, and if possible make some replicas and try them out. That, of course, is a really nifty way - only quite difficult because of the scarcity of finds and (you know the sad song by now) because it's oh-so-hard to find published needles.
The other way is by deduction. Nobody can tell me that medieval people (or people in what age soever) bought extremely costly materials like gold thread and fine silk to weave enormously fine fabrics and embroider them all over with beautiful, awe-inspiring motifs using a (needle) bodkin (for the Germans: "Nähdolch" is the term. The term.) and dragging this huge metal abnormity through their costly fine fabric! Fine fabrics require fine tools, after all. And at least I have not had much fun running my well-beloved copper alloy sewing needles through linen or silk instead of wool; they are just not suited to these. So fabric type makes a difference, too.
Deduction, though, will only tell us that some fine needles must have been there, out of due necessity, but no more than they must have been suitable for this or that work and material. So it's back to no. 1 for harder evidence.
There are a few needles in my picture collection, so I bring to you: The Needle Parade!
First, from the glorious and long-past 3rd and 4th century, needle boxes and needles on one of my bad photographs, taken in the Historical Museum Oslo, viking section.
Next finds from Konstanz (Lake Constance), from the 14th century, an array of small things including sewing needles. From LANDESDENKMALAMT BADEN-WÜRTTEMBERG und STADT ZÜRICH (Hrsg.): Stadtluft, Hirsebrei und Bettelmönch. Die Stadt um 1300. Stuttgart 1992. P. 433.
Everybody knows this copper needlecase missing its lid, from the late 14th century London. It still contained an iron needle - and that needle size would match a modern sewing needle. From CROWFOOT, ELISABETH, PRITCHARD, FRANCES und STANILAND, KAY: Textiles and Clothing c. 1150-c.1450. Medieval Finds from Excavations in London:4. London 1992. P. 151. There you go:
From a special exhibition in the Alamannenmuseum Ellwangen, a needle from the graves at Kirchheim/Ries. My photo, taken with kind permission. It lacks scale, but I would use a needle like that in daily life without finding it special. Graves at Kirchheim/Ries date to the early middle ages, between 6th and 8th century if I remember correctly.
Again from the 14th century: Needles and thimbles from Copenhagen, National Museum, photo taken in the Medieval Section. If you come to Copenhagen, make double sure you visit that wonderful museum - reserve a full day for it, if you can. It is worth it.
That's all I have gathered together during the years - but at least it shows steel sewing needles from as early as at least the early middle ages. If any of you have more needles, please give me a hint - I'm collecting evidence ; )
