In Norse mythology, there is a war between the Winilers and the Vandals. Odin takes the side of the Vandals and his wife Frigga takes the side of the Winilers. Odin says he will help whoever he sees first the next morning. Frigga makes a plan that the women tie their long hair under their chins like a beard to disguise themselves as men and she moves the bed so Odin faces the window the women are standing near. He names them Long-Beards (Lombards) and helps them to victory.

Many decorating techniques used today do not require elaborate cookie cutters. The simplest of shapes can be quite versatile in serving various themes. For example, a star-shaped cutter can be used for Christmas, 4th of July, and messages of congratulations. A circle can be decorated as a sun, ball, flower, spider web, or smiley face. This cutter is in the shape of a four leaf clover.

This figure represents a crystal of iron pyrite showing representatives of all the forms of the isometric system except the rhombic dodecahedron: ∞O∞ {100} (P); O, {111} (d); [∞O2/2], π{102} (e); [4O2/2], π{214} (s); 2O2, {211} (o); and 3O, {133} (t). It is shortened in the direction of one of the principal axes, which, together with the fact that only two of the three faces belonging to the forms s, o, and t are developed in each octant, gives to it a decidedly orthorhombic habit.

Cubes of Iron Pyrites frequently show a striation of their planes in one direction, which is perpendicular to the striation  on all contiguous faces, owing to oscillatory combination with the pentagonal dodecahedron. This would not be possible in a holohedral cube.

Curvature of crystal planes is quite a constant property of some substances. It may be due to a very fine oscillatory combinations or to an irregularity of growth and a want of perfect parallelism between sub-individuals. A common instance is the Diamond, whose faces, except those of the octahedron, are almost always curved.

"And they arose before the morning on the five and twentieth day of the ninth month (which is the month of Casleu) in the hundred and forty-eighth year. And they offered sacrifice according to the law upon the new altar of holocausts which they had made. According to the time, and according to the day wherein the heathens had defiled it, in the same was it dedicated anew with canticles, and harps, and lutes, and cymbals. And all the people fell upon their faces, and adored, and blessed up to heaven, him that had prospered them. And they kept the dedication of the altar eight days, and they offered holocausts with joy, and sacrifices of salvation, and of praise." 1 Maccabees 5:52-56 DRA

"And there were in the same country shepherds abiding in the field, keeping watch over their flock by night. And, lo, the angel of the Lord came upon them, and the glory of the Lord shone round about them: and they were sore afraid. And the angel said unto them, Fear not: for, behold, I bring you good tidings of great joy, which shall be to all people. For unto you is born this day in the city of David a Saviour, which is Christ the Lord. And this shall be a sign unto you; Ye shall find the babe wrapped in swaddling clothes, lying in a manger. And suddenly there was with the angel a multitude of the heavenly host praising God, and saying, Glory to God in the highest, and on earth peace, good will toward men." Luke 2:8-14 KJV
