Task: Question Answering
Input (English): Passage: However, slaves did belong to their master's household. A newly-bought slave was welcomed with nuts and fruits, just like a newly-wed wife. Slaves took part in most of the civic and family cults; they were expressly invited to join the banquet of the Choes, second day of the Anthesteria, and were allowed initiation into the Eleusinian Mysteries. A slave could claim asylum in a temple or at an altar, just like a free man. The slaves shared the gods of their masters and could keep their own religious customs if any.Slaves could not own property, but their masters often let them save up to purchase their freedom, and records survive of slaves operating businesses by themselves, making only a fixed tax-payment to their masters. Athens also had a law forbidding the striking of slaves: if a person struck what appeared to be a slave in Athens, that person might find himself hitting a fellow-citizen, because many citizens dressed no better. It astonished other Greeks that Athenians tolerated back-chat from slaves. Athenian slaves fought together with Athenian freemen at the battle of Marathon, and the monuments memorialize them. It was formally decreed before the battle of Salamis that the citizens should "save themselves, their women, children, and slaves".Slaves had special sexual restrictions and obligations. For example, a slave could not engage free boys in pederastic relationships ("A slave shall not be the lover of a free boy nor follow after him, or else he shall receive fifty blows of the public lash."), and they were forbidden from the palaestrae ("A slave shall not take exercise or anoint himself in the wrestling-schools."). Both laws are attributed to Solon. Fathers wanting to protect their sons from unwanted advances provided them with a slave guard, called a paidagogos, to escort the boy in his travels.
The sons of vanquished foes would be enslaved and often forced to work in male brothels, as in the case of Phaedo of Elis, who at the request of Socrates was bought and freed from such an enterprise by the philosopher's rich friends. On the other hand, it is attested in sources that the rape of slaves was prosecuted, at least occasionally. 
Question: What is the name of the man who put forth a law preventing slaves from engaging free boys in pederastic relationships?
Output (English): Solon.
