Gos"sa*mer (?), n. [OE. gossomer, gossummer, gosesomer, perh. for goose summer, from its downy appearance, or perh. for God's summer, cf. G. mariengarr gossamer, properly Mary's yarn, in allusion to the Virgin Mary. Perhaps the E. word alluded to a legend that the gossamer was the remnant of the Virgin Mary's winding sheet, which dropped from her when she was taken up to heaven. For the use of summer in the sense of film or threads, cf. G. Madchensommer, Altweibersommer, fliegender Sommer, all meaning, gossamer.]
