k Ralegh also for material
assistance both with money and with advice in the compilation of his
celebrated collection of voyages. The manuscript, for example, of the
Portuguese narrative of de Gama's voyage in 1541 to the Red Sea had been
bought for L60 by Ralegh, who presented it to him. Ralegh again was 'at
no small charges' towards the production by the French painter, Jacques
Morgues, of a series of coloured illustrations of Florida, whither he
had accompanied Laudonniere. In 1586 the publisher of John Case's
_Praise of Music_ dedicated it to Ralegh, as a virtuoso. In 1588
Churchyard dedicated to him the _Spark of Friendship_. Hooker, the
antiquary, introduced the continuation of the Irish history of Giraldus
Cambrensis with a fervent encomium on the illustrious Warden of the
Stannaries, who was 'rather a servant than a commander to his own
fortune.' A medical treatise was inscribed to him as an expert. A list
which has been preserved of his signs for chemical substances and drugs,
shows that as early as 1592 he had paid attention to medicine. He
appears to have kept amanuenses to copy interesting manuscripts. Thus,
John Peirson who, in 1585, was in trouble in connexion with a tract
entitled _Reasons why the King of Scots is unacceptable to the People of
England_, deposed that he delivered one of the five copies he made to
'Sir Walter Ralegh, my master.'

Throughout life he befriended Hariot, the universal philosopher, as he
has been called. Hariot has been credited with the invention of the
system of notation in Algebra. He discovered the solar spots before, and
the satellites of Jupiter almost simultaneously with, Galileo. Hariot,
who numbered Bishops among his admirers, was accused by zealots of
atheism, because his cosmogony was not orthodox. They discerned a
judgment in his death in 1621 from cancer in the lip or nose. His ill
repute for free-thinking was reflected on Ralegh who hired him to teach
him mathematics, and engaged him in his colonizing projects. Ralegh
introduced him to the Earl of Northumberland, who allowed him a liberal
pension. But new ties did not weaken the old. Hariot and he remained
constantly attached. Hariot was the friend whose society he chiefly
craved when he was recovering from his wound in the Tower. During his
long imprisonment Hariot was the faithful companion of his studies.
Hariot brought to his notice another Oxford man, Lawrence Key
