Hallo everyone, hearing discussiong about symbols I thought again about mine specific symbols. While I have to admit I have perhaps not searched thoroughly, I have not found any included in therion. Well, I would be willing to design some. But it surely would be better to determine which symbols/areas would be needed first. Many of these are already in convention elsewhere, so work should be relatively straightforward. To begin I have the following suggestions. Unforunately my english is not good enough, so to avoid possible confusion I add the german words. I would be glad if a german speaker could name the translations. 1. Shaft / Schacht (up and down) 2. Sinking (?) / Gesenk 3. Weather (ventile) door / Wettertür 4. Doorway (for supporting) / Türstock (standing and ruined) 5. Where ore was mined / Abbau (up and down) 6. Hole for rolling ore downwards / Rolloch 7. Wagon rolling planks / Hundbretter 8. Hand driven wind / Haspel 9. Chamber for hand driven wind / Haspelkammer 10. Water flowing gutter / Gerinne 11. Lamp niche / Lampennische 12. Upraise / Aufhauen 13. Galley end (constr. end) / Ortsbrust 14. Hewn material / Versatz 15. Versturz 16. Special tool traces / Werkzeugspuren (Please add to the list) If I provide drawn symbols, would anyone help me converting these to metapost? It would also be nice if fellow miners would suggest symbols, too. Best greetings, and to my fellow miners a hearty Barbara's day!
