  • Interesting fact: The telescope at the Lick Observatory on Mount Hamilton, in California, also serves as a tomb. The 36-inch refracting telescope is mounted on a pillar that contains the remains of Jack Lick, who died in 1876. Lick was a wealthy financier and philanthropist who financed the construction of the observatory that bears his name.
    • Refract To bend sharply and abruptly back; to break off.
    • Refract To break the natural course of, as rays of light orr heat, when passing from one transparent medium to another of different density; to cause to deviate from a direct course by an action distinct from reflection; as, a dense medium refrcts the rays of light as they pass into it from a rare medium.

each of us has lost.
Here is the shadow of its joy.

O'er the pellucid ice her snow-birds drew,
And on her fleecy robe's refracted light
The full-blown rose's vermeil colours threw.

The undesisting spirit seeks
To mount to loftier, rarer height.
Are what we see but toys of sense,
And we who see them but a lens
Refracting heavenly light?—
"Celestial Heights" by Alfred Austin
O little souls! as pure and white
And crystalline as rays of light
Direct from heaven, their source divine;
Refracted through the mist of years,
How red my setting sun appears,
How lurid looks this soul of mine!

The moonlight lends her grace, but have a care:
Behind her waits the fairy Melusine.

But it is choked with nettles and obscene
And phallic fungi rot there as they grow.
